Description
Field of the Invention
[0001] The present invention relates to a test module for measuring system electronic components of a basic module of a (modular) electronic vibration measurement system and / or an electronic vibration measurement system electrically connected to the basic module, and a test device. The present invention also relates to a method for starting up and / or checking / testing a (modular) electronic vibration measurement system using such a test module or such a test device. Background Art
[0002] Modular electronic vibration measurement systems are disclosed in WO 2019 / 017891 A or WO 2021121867 A and (not pre-published) German patent applications DE102021105397.8, DE 102020133614.4, DE 102020132685.8, DE 102020133851.1, DE102020133566.0, DE 102020132986.5, DE 102020132686.6, DE 102020132685.8, DE102020131452.3, DE 102020132223.2, DE 102020127356.8, DE 102020114519.5 or DE102020112154.7. The system consists of a basic module, an electronic vibration module mechanically connected to the basic module, and measurement system electronic components electrically connected to the basic module, and is used to detect at least one measured variable of a fluid measured substance flowing in a (measured substance) pipeline, that is, to determine the measured value of one or more measured variables. For example, the mass flow rate, volume flow rate, density and / or viscosity of the measured substance.
[0003] The basic module of such a (modular) electronic vibration measurement system has a (protective) housing having at least one chamber at least partially enclosed by the housing wall, and one or more electrical coils, such as cylindrical and / or designed as air coils, which are placed in the chamber of the (protective) housing at a certain distance from each other and are at least indirectly mechanically connected to the housing wall. Each coil is also electrically connected to the measurement system electronics. The measurement system electronics can be at least partially mounted in the (protective) housing and / or at least partially mounted outside the (protective) housing, for example in a separate electronics housing. In particular, the basic module is also configured to receive the electronic vibration module of the measurement system and to be mechanically firmly connected to it (forming a vibration-type measurement transducer), but still detachably connected to it, in particular to form a vibration-type measurement sensor or the electronic vibration measurement system itself; in particular, this is also achieved in such a way that the electronic vibration module is locked in the basic module or cannot move. The electronic vibration module of the corresponding measurement system is also designed to be replaceable, such that it can be inserted into the chamber, in particular on-site from outside the (protective) housing of the basic module or through an (insertion) opening provided in the housing wall; and it can be removed from the basic module again in a non-destructive manner, possibly even without tools, in particular from outside the housing and / or through a (sliding-in) opening of the housing, or without manipulating or removing the basic module itself from the (process) equipment. Furthermore, this also makes it possible to subsequently insert an electronic vibration module into a basic module already installed on-site or to replace a defective or worn-out electronic vibration module on-site with a new and intact one, where the new electronic vibration module is designed for single use or only for use within a specified time period ("disposable").
[0004] The electronic vibration module also has one or more permanent magnets, such as cylindrical permanent magnets, and is also configured to be mounted in the basic module such that each permanent magnet is placed in the aforementioned chamber but spaced apart from the housing wall, in particular such that each permanent magnet is held in a static mounting position where the orientation and / or minimum distance relative to one of the electrical coils in the basic module is predetermined in each case, and the respective imaginary longitudinal axes of each permanent magnet and at least one electrical coil are aligned with each other or extend parallel to each other.
[0005] In the measurement system under discussion, each electronic vibration module also has at least one (measurement) tube, for example at least partially straight and / or at least partially curved, the tube wall forming the housing surface of the tube, especially made of metal or plastic, and having a lumen enclosed by the same tube wall, especially two substantially identical parallel (measurement) tubes, and each of the permanent magnets mentioned above is mounted on the outside of the tube wall, especially at the ends of the first section and the second section, i.e., two substantially identical parallel (measurement) tubes, and each of the permanent magnets mentioned above is fixed on the outside of the tube wall, especially fixed on the central section of the tube wall, which central section extends between the end of the first section and the second section remote from that section end, especially connected to the tube wall by means of a material bond. Furthermore, the electronic vibration module or at least one of its (measurement) tubes is designed to be installed in the housing without tools, such that the tube is at least partially (especially completely) placed in the chamber, but still spaced apart from the housing wall; and, each of the permanent magnets forms a voice coil together with a corresponding electric coil at the respective installation position - especially serving as an electrodynamic oscillation exciter, and / or a plunger coil - especially serving as an electrodynamic oscillation sensor. In the case of an at least partially curved (measurement) tube, the above-mentioned central section can be, for example, substantially U-shaped or V-shaped.
[0006] In such an electronic vibration measurement system, each of the above-mentioned (measurement) tubes is also configured to carry, during operation, the fluid under test flowing within the lumen of the tube, in particular having a predefinable flow direction and / or a flow direction pointing from the end of the first section towards the end of the second section, and to vibrate simultaneously to generate a measurement effect related to one or more measured variables of the substance under test, in particular in such a way that the central section performs an oscillatory movement about a static rest position and / or the (measurement) tube is driven by at least one of the above-mentioned (energized) voice coils and / or an (alternating) voltage representing the oscillatory movement of at least one tube, thus serving as an oscillation signal, generated by the above-mentioned plunger coil. The measurement system electronics of such a measurement system are then correspondingly configured with the aid of an electrical drive signal, in particular by applying an alternating current and / or applying an (alternating current) frequency which essentially corresponds to the resonance frequency of at least one tube, feeding electrical power into at least one electrical coil forming the above-mentioned voice coil and / or by means of an (alternating) voltage generated by at least one electrical coil forming the above-mentioned plunger coil, to determine the measured value of one or more measured variables of the substance under test flowing through the (measurement) tube. In the case of a measurement system designed as a Coriolis mass flowmeter or a measurement system designed as a Coriolis mass flow / density meter, for example, a (mass flow) measured value representing the mass flow is generated based on the (measured) phase difference between the above-mentioned two oscillation signals caused by the Coriolis force and on the phase difference-versus-measured value characteristic function set in the measurement system electronics. The phase difference-versus-measured value mass flow characteristic function can be, for example, a (linear) parametric function, the (scale) zero point of which corresponds to the (measured) phase difference between the two oscillation signals, which can be measured when the substance under test is at rest or when the mass flow is zero; its slope corresponds to the (measurement) sensitivity of the measurement system or to the change in the (measured) phase difference associated with the change in mass flow. Since the one or more resonance frequencies of at least one tube also depend in particular on the instantaneous density of the respective substance under test, it is thus possible, with the aid of such a measurement system, to directly measure, in addition to the mass flow, the density of the respective substance under test flowing through the tube by means of the (alternating current) frequency of the drive signal and / or by means of the (signal) frequency of at least one oscillation signal. The measurement system electronics of the measurement system of the type under discussion are therefore usually also equipped to generate a (density) measured value representing the density based on the (alternating current) frequency of the above-mentioned drive signal and / or based on the corresponding signal frequency of at least one oscillation signal, for example, using the operating frequency-versus-measured value characteristic curve function correspondingly configured in the measurement system electronics. In addition, it is also possible to directly measure the viscosity of the substance under test flowing through, for example, based on the excitation energy or excitation power required to maintain a useful oscillation and / or based on the decay of the excitation (resonance) oscillation caused by the dissipation of oscillation energy, or by using the decay-versus-measured value characteristic curve function correspondingly set in the measurement system electronics.Furthermore, with such an electronic vibration measurement system, other measured variables originating from the above-mentioned flow rate and / or substance parameters, such as the Reynolds number, can be easily determined.
[0007] To simplify the commissioning of the measurement system formed in this way, the electronic vibration module can also have at least one identification element that involves or bears identification information about the electronic vibration module, for example, a bar code, QR code, or RFID tag attached to at least one tube, and / or the base module can have at least one light-emitting semiconductor element located within the (protective) housing and connected to the measurement system electronics, for example, a light-emitting diode (LED), and / or one or more radio transmitters / receivers (RF transceivers) and / or optoelectronic sensors, for example, one or more CCD optoelectronic sensors and / or one or more CMOS optoelectronic sensors, each located within the (protective) housing and connected to the measurement system electronics.
[0008] It is also necessary to regularly check the functional efficiency of the electronic vibration measurement system of the type under discussion or any deviation from a predetermined corresponding reference state, for example, in the state determined by the manufacturer or at the manufacturer's factory and / or during on-site calibration or commissioning of the corresponding measurement system, for example, in order to be able to detect at an early stage any reduction in the functionality or measurement accuracy of the measurement system associated with an increasing deviation from the reference state, and map the measured variables that the measurement system will ultimately record, especially the mass flow rate and density, into the corresponding measured values. A reduction in the functionality or measurement accuracy of such a measurement system may manifest as, for example, an almost irreversible change in the impedance of the above-mentioned oscillating coil and / or immersion coil, and / or a permanent reduction in the mechanical connection stability between the base module and the electronic vibration module, or a permanent reduction in the positioning accuracy of the electronic vibration module within the base module, or may be caused by thermal overload and / or mechanical overload, for example, due to too high or too low temperature within the base module (i.e., especially temperatures outside the specifications), aging, an increase in moisture or condensation within the base module, and / or wear of the base module components caused by frequent replacement of the electronic vibration module. Other influencing factors that at least indirectly and / or at least temporarily impair the functionality of the measurement system include multi-frequency and / or high-frequency electromagnetic (external) radiation or fields (EMC) propagating within the base module, or (external) sound waves propagating within the base module, for example, in the form of structure-borne sound.
[0009] Therefore, it must generally be assumed that one or more system functions (transfer functions) inherent in the measurement system have also changed compared to the (reference) system function inherent in the corresponding original measurement transducer, where each system function characterizes the functional dependence of the above-mentioned oscillation signal on the corresponding drive signal, or one or more functional dependencies of the oscillation signal on the drive signal and the corresponding flow rate and / or material parameters of the substance being measured. Examples of such system functions of the measurement system include the mass flow rate and phase difference system function, according to which the above-mentioned (measured) phase difference of the oscillation signal depends on the mass flow rate, or the density and resonance frequency system function of the transducer, according to which the resonance frequency or frequencies of at least one tube depend on the density of the substance being measured. Thus, such (over)loading of the measurement transducer will also affect the measurement functions of the measurement system that involve the above-mentioned system functions, according to which the measurement system as a whole converts the corresponding measured variable to be recorded into a corresponding measured value. For example, the characteristic curve function composed of the above-mentioned mass flow rate and phase difference system function and the phase difference and mass flow rate measured value characteristic curve function, i.e., the characteristic function implemented in the measurement system electronics, according to which a determined phase difference is converted into a mass flow rate measured value, i.e., the mass flow rate and measured value measurement function of the measurement system, according to which the determined mass flow rate measured value depends on the mass flow rate. The phase difference and mass flow rate measured value characteristic curve function can be, for example, a (linear) parametric function, whose (scale) zero point corresponds to the (measured) phase difference measured when the substance being measured is at rest, and whose (measured) sensitivity corresponds to the change in the (measured) phase difference associated with the change in the mass flow rate (the slope of the characteristic curve function). Other examples of such system functions may also be affected by interference or the resulting measurement functions, which include the density and resonance frequency system function of the transducer, or the density and measured value (measurement) function of the measurement system involved therein, and the resonance frequency and density characteristic function of the measurement system electronics, and / or the viscosity and damping system function of the transducer, or the viscosity and measured value (measurement) function of the measurement system involved therein, and the damping and viscosity measurement characteristic function of the measurement system electronics. The change in the corresponding system function may thus have, for example, the following effects: one or more of the corresponding characteristic curve parameters of one or more of the above-mentioned characteristic curve functions drift, for example, in the case of a linear parametric function, resulting in a drift of its zero point and / or its slope. The irreversible changes that may occur in one or more of the system functions or measurement functions of the measurement system sometimes also cause the entire measurement system to malfunction, such that the high measurement accuracy typically envisioned for such a measurement system can no longer be guaranteed, which means that the functionality of the measurement system is significantly impaired and may even be suspended, or the affected measurement system experiences a corresponding serious failure.
[0010] Taking this into account, measurement systems of this type usually need to undergo corresponding (re)checks, for example, at fixed time intervals during regular predictive maintenance; such that the functionality of the electronic vibration module or the entire measurement system is checked on-site during a time-controlled (self-)diagnosis process of the measurement system and / or triggered by corresponding control commands transmitted to the electronic components of the measurement system, approximately so that appropriate repair or replacement measures can be initiated as soon as necessary, especially when a fault in the measurement system is detected. For electronic vibration measurement systems of the type under discussion, such (repair or replacement) measures regularly involve replacing a faulty electronic vibration module with a new one, which can also be done quickly and easily on-site. However, a disadvantage of such a test process is that only the functionality of the entire measurement system can be verified, or conversely, any detected fault cannot be precisely located within the measurement system, i.e., it cannot be assigned to the basic module, the electronic vibration module, or the electronic components of the measurement system. In particular, such (self-)diagnostic methods cannot easily identify faults in the basic module or the electronic components of the measurement system electrically connected thereto that only impair the measurement accuracy, in such a way that during such an inspection of a measurement system of the type under discussion, it can also be determined whether the basic module and / or the electronic components of the measurement system need to be replaced.

[0064] Figure 1 and 2 Figures 3a and 3b schematically show exemplary embodiments of a (modular) electronic vibration measurement system, which is particularly intended for detecting at least one measured variable of a fluid to be measured flowing in a (measured substance) pipeline, i.e., for determining the measured values of one or more measured variables, such as the mass flow rate, volume flow rate, density, and / or viscosity of the measured substance. For this purpose, the measurement system includes a basic module M1, an electronic vibration module M2, and, for example, programmable measurement system electronics ME. The measurement system electronics ME can be formed, for example, by means of one or more microprocessors (µC), and / or have display and operating elements, for example, formed by means of a touch display screen, for example, for displaying the measured values and / or operating data of the measurement system. The basic module M1 has a (protective) housing 11, which has at least one chamber 11* at least partially enclosed by a housing wall 11+; and has at least one first electric coil 12, for example, cylindrical and / or designed as an air coil, which is placed in the chamber 11* of the (protective) housing and is at least indirectly mechanically connected to the housing wall 11+ and electrically connected to the measurement system electronics ME; and the electronic vibration module M2 has at least one, for example, cylindrical first permanent magnet 22. As is common in measurement systems of the type under discussion, the measurement system electronics ME can also be at least partially accommodated in the chamber 11* and / or at least partially outside the chamber 11*, in particular in the electronic housing 100 of the measurement system, or designed in a modular manner. The measurement system can be designed, for example, as a modular Coriolis mass flowmeter and / or corresponding to the patent applications WO 2019 / 017891A1, WO 2021121867A1, DE 102021105397.8, DE102020133614.4, DE 102020132685.8, DE 102020133851.1, DE 102020133566.0, DE102020132986.5, DE 102020132686.6, DE 102020132685.8, DE 102020131452.3, DE102020132223.2, DE 102020127356.8, DE 102020114519.5, and DE 102020112154.7 mentioned at the beginning.
[0065] As Figure 3a and 3b shown in the schematic diagram, or from Figure 1 and 2、In the combination of 3a and 3b, it can be easily seen that the basic module M1 is specifically configured to receive the electronic vibration module M2 and be connected to it in a mechanically fixed but detachable manner, for example, such that the electronic vibration module M2 is locked in the basic module M2, and / or such that the electronic vibration module can also be (subsequently) inserted on-site, that is, inserted into the already installed basic module (in the device). In particular, the basic module M1 and the electronic vibration module M2 are further configured to be assembled or assembled to form a vibration-type measurement sensor (of the measurement system), such that the electromechanical oscillation exciter and / or (electrodynamic) oscillation sensor of the measurement system are formed by means of the electric coil 12 (connected to the measurement system electronics ME) and by means of the permanent magnet 22. According to another embodiment of the present invention, the electronic vibration module is specifically configured to be installed in the basic module such that its permanent magnet 22 is placed within the chamber 11*, but at a certain distance from the housing wall 11+, that is, specifically in a static (first) installation position E1 predetermined with respect to the orientation and / or minimum distance of the electric coil 12, and / or maintained such that the imaginary longitudinal axis of the first permanent magnet and the imaginary longitudinal axis of the electric coil 12 are aligned with each other or extend parallel to each other. In particular, the permanent magnet 22 is further configured to form a voice coil together with the electric coil 12 in the installation position E1, for example, used as an electrodynamic oscillation exciter, and / or a plunger coil, for example, used as an electrodynamic oscillation sensor. According to another embodiment of the present invention, the electronic vibration module M2 and the basic module M1 are further configured to be assembled and / or disassembled without tools, especially non-destructively, especially also on-site, such that the electronic vibration module can be non-destructively removed from the basic module M1 again. Alternatively or additionally, the electronic vibration module M2 is designed to be replaceable or configured to be removable, especially non-destructively, especially also removable on-site from the outside of the housing and / or through the (insertion) opening provided in the housing wall 11+ of the (protective) housing 11; and / or the electronic vibration module M2 is also configured to be installed in the basic module M1 especially on-site, especially such that it can be inserted into the chamber 11* from the outside of the (protective) housing 11 or through the (insertion) opening. For example, this can be done without manipulating the basic module M1 itself or removing it from the corresponding (processing) device. If necessary, the above-mentioned (sliding-in) opening can also be sealed with a suitable lid after the installation of the electronic vibration module, for example, a dust-proof, strong water jet-proof, and / or explosion-proof lid. Therefore, it is also possible to easily replace a defective or worn (old) electronic vibration module, which can only be used once or only within a specified period ("disposable"), with a new and intact electronic vibration module on-site. To support the correct installation of the electronic vibration module M2 into the basic module M1, the electronic vibration module M2 and the basic module M1 can each have corresponding guiding structures or elements, for example, a corresponding (guiding) groove on one of the two modules (M1, M2), and a (guiding) spring and / or (guiding) pin on the other of the two modules, which slide during assembly.To further simplify the commissioning of the measurement system, the electronic vibration module M2 can further include at least one identification element 28, such as a bar code, QR code or RFID tag (RFID TAG), which relates to or bears identification information about the electronic vibration module M2, and / or the basic module M1 can have at least one light-emitting semiconductor element 19a, such as a light-emitting diode (LED), located within the (protective) housing and connected to the measurement system electronics (into chamber 11*), for reading the identification element 28, and / or one or more radio transmitters / receivers (RF transceivers), each located within the (protective) housing and connected to the measurement system electronics, and / or a photosensor 19b (sensitive to the light illuminating chamber 11*), such as one or more CCD photosensors and / or one or more CMOS photosensors.
[0066] According to another embodiment of the invention, the electronic vibration module M2 has at least one second permanent magnet 24, which is located at a certain distance from the permanent magnet 22 and is specifically cylindrical and / or has the same structure as the permanent magnet 22. In addition, the basic module M1 correspondingly has at least one second electric coil 14, which is located within the chamber 11* of the (protective) housing, for example, cylindrical and / or designed as an air coil and / or has the same structure as the first electric coil 12. The second electric coil 14 (away from the electric coil 12) is at least indirectly mechanically connected to the housing wall 11+ and is also electrically connected to the measurement system electronics. The basic module is further configured to receive the electronic vibration module such that the permanent magnet 24 is held in a second mounting position, in particular with respect to the orientation and / or distance from the first mounting position, or the imaginary longitudinal axes of the permanent magnet 24 and the electric coil 14 are aligned with each other or extend parallel to each other. In addition, the electronic vibration module M2 can also have more than two permanent magnets (22, 24) arranged at a certain distance from each other, and thus has at least one third permanent magnet 26; and the basic module M1 can also have more than two electric coils (12, 14) arranged at a certain distance from each other within the chamber 11*, and thus has at least one third air coil 16.
[0067] According to another embodiment of the invention, the electronic vibration module M2 has at least one (first) tube 31, the wall of which forms the outer shell surface of the tube 31, for example, made of metal or plastic, and has a lumen 21* wrapped by the same wall, and the permanent magnet 22 is fixed to the outside of the wall, for example, connected thereto by a material adhesive. As Figure 1 Schematically shown, at least one tube 31 can be at least partially straight and / or at least partially curved, for example, such that the central section of the wall extending between the first end and the second end away from the first end of the wall is designed as a U-shape or a V-shape, and / or as Figure 1Schematically shown, at least one permanent magnet 22 is attached to the outer side of the above-mentioned central section. The permanent magnet 24 of the electronic vibration module M2 and / or other permanent magnets (26) can also be attached to the outer side of the central section, for example. In addition, at least one tube 31 is also particularly intended to be incorporated into the basic module M1 in the above-mentioned manner and also into the line of the (substance to be measured) pipeline - for example, a hose pipeline or a pipe pipeline. In addition, at least one tube 31 is specifically configured to carry a fluid substance to be measured in its lumen, and the fluid substance to be measured particularly flows at least temporarily in a predetermined flow direction, for example, from the end of the aforementioned first section to the end of the aforementioned second section, for example, via the aforementioned (substance to be measured) pipeline, and vibrates during this process; in particular, it is also made such that at least one tube 31 performs forced bending or resonance oscillation around a static rest position, and / or moves at least one permanent magnet 22 relative to the electric coil 12. Such mechanical oscillation of at least one (measurement) tube 31 or its central section can be excited or maintained, for example, by means of the oscillation exciter formed by the permanent magnet 22 and the coil 12 as mentioned above, and / or detected by the above-mentioned oscillation sensor specifically formed (by means of the permanent magnet 22 and the coil 12), so that at least one oscillation signal representing the same oscillation of the tube 31 or its central section is provided by the oscillation sensor. In particular, in order to enable at least one (measurement) tube 31 - especially the above-mentioned central section - to perform such vibration, the electronic vibration module M2 according to another embodiment of the present invention is further configured to be installed in the basic module M1 or its (protective) housing 11, so that also as Figure 3a Schematically shown, the at least one (measurement) tube 31 is at least partially - for example, also completely - placed within the chamber 11*, however, at least its above-mentioned central section is spaced apart from the housing wall 11+.
[0068] Similar to such an electronic vibration module or an electronic vibration measurement system constituted thereby, the electronic vibration module M2 may further have at least one second (measurement) tube 32. For example, its structure and / or function are also the same as those of the first tube. Its tube wall forms the outer shell surface of the second tube, particularly made of metal or plastic, and its lumen is also wrapped by the same tube wall. In this case, the aforementioned second permanent magnet 24 can be fixed to the second tube relative to the permanent magnet 22 fixed to the first tube 31, particularly, connected to it by material connection. For example, the imaginary longitudinal axis of the permanent magnet 24 can also be aligned with or extend parallel to the imaginary longitudinal axis of the permanent magnet 22. The first (measurement) tube 31 and the second (measurement) tube 32 can also be fluidly connected to each other by means of a first diverter on the inlet side and a second diverter on the outlet side, which is very common in an electronic vibration measurement system of the type under discussion and can also be integrated into the circuit of the aforementioned (substance to be measured) pipeline during the operation of the measurement system. Especially for the case where the above-mentioned electronic vibration module M2 is formed by means of two tubes (31, 32), the electronic vibration module M2 can also have more than three permanent magnets arranged at a certain distance from each other, for example, at least six permanent magnets in total. Correspondingly, the basic module M1 can have more than three electric coils arranged at intervals in the chamber 11*, for example, at least six electric coils in total. For example, each electric coil is also designed as an air coil.
[0069] In order to excite and maintain the mechanical oscillation of at least one (measurement) tube 31 or the electronic vibration module M2 formed therewith, according to another embodiment, the measurement system electronic component ME is further configured to provide a first electrical (measurement system) drive signal and introduce it into at least one electric coil (12, 14) of the basic module M2, for example, the coil 12 and / or the aforementioned coil 14, so as to feed the electric power required for the aforementioned mechanical oscillation into at least one electric coil. In particular, in such a way that at least one (measurement system) drive signal has an applied alternating current and / or at least one signal frequency corresponding to the mechanical resonance frequency of the electronic vibration module M2, particularly its at least one (measurement) tube 31. In the above case, in addition to the electric coil 12, the basic module M1 further includes at least the electric coil 14. The measurement system electronic component ME can be further configured to feed electric power into the second electric coil 14 by means of a second electrical (measurement system) drive signal, particularly by an applied alternating current and / or a signal frequency corresponding to the mechanical resonance frequency of the electronic vibration module or its at least one (measurement) vane and / or simultaneously with the first drive signal.
[0070] According to another embodiment of the present invention, the measuring system electronic component ME is further configured to, for example, detect and evaluate a first electrical (alternating current) voltage induced, for example, by the electrical coil 12 (14) in the electrical coil 12 and / or the aforementioned coil 14, and, for example, use the (alternating current) voltage to determine a (parameter) measured value of at least one parameter of the (alternating current) voltage, such as, for example, amplitude, frequency, and / or phase angle, and / or calculate a measured value of at least the measured variable detected by the measured substance based on the (alternating current) voltage or the (parameter) measured value determined therefor. In addition, the measuring system electronic component ME may further be configured to calculate a measured value of the inductance of the electrical coil based on the (AC) voltage or the (parameter) measured value determined therefor, for example, in order to correspondingly consider these measured values when checking the functionality of the measuring system, or in order to compare the determined inductance of the first electrical coil 12 with a previously determined (inductance) reference value and / or one or more thresholds predetermined therefor. Alternatively or additionally, the measuring system electronic component ME may further be configured, for example, to compare one or more of the above (parameter) measured values with one or more (parameter) reference values determined in advance therefor and / or one or more thresholds predetermined therefor in order to check the functionality of the measuring system. In the above case, in addition to including the electrical coil 12, the basic module M1 further includes at least the electrical coil 14, and the measuring system electronic component may further be configured to detect and evaluate a second electrical (alternating current) voltage induced by the second electrical coil in the coil 14, for example, calculate a (parameter) measured value of at least one parameter of the second (alternating current) voltage and / or a phase difference established between the first (alternating current) voltage and the second (alternating current) voltage based on the second (alternating current) voltage, for example, in order to calculate a measured value of at least one measured variable to be detected by the measured substance. According to another embodiment of the present invention, the measuring system electronic component is further particularly configured to use the phase difference established between the first (alternating current) voltage and the second (alternating current) voltage to obtain a measured value of at least one measured variable - particularly the mass flow rate - of the flowing fluid, and / or the measuring system electronic component is configured to determine and evaluate the (parameter) measured value of the aforementioned phase difference, for example, by comparing one or more (parameter) measured values of the phase difference with a previously determined (parameter) reference value and / or one or more thresholds predetermined therefor. Alternatively or additionally, the measuring system electronic component may further be configured to determine a measured value of the inductance of the second electrical coil.
[0071] In order to be able to very easily check or verify the functionality of the basic module M1 itself and / or the measuring system electronic component ME electrically connected thereto or the subsystem formed thereby, if necessary, also during commissioning and / or cyclically on-site (check or verification), according to the present invention, a corresponding Test module PM ( Figure 4to 7), which has, for example, a monolithic and / or plate-shaped and / or tubular carrier element 41 and at least one first test element 42 for generating a magnetic field, which test element is in particular electrical and / or magnetic and / or electronic and / or is arranged on a printed circuit board of the test module PM and is mechanically connected to the carrier element 41 - for example, a permanent magnet. The carrier element 41 can be composed of or made of, for example, metal and / or plastic, for example, at least partially embedded in at least one test element 41 or the above-mentioned printed circuit board, and, for example, an outer protective layer of the carrier element 41 can also be formed by means of the above-mentioned plastic. The above-mentioned plastic can be, for example, a chemically resistant and / or high-strength plastic, such as polycarbonate (PC) or polyether ether ketone (PEEK).
[0072] According to the present invention The test module PM is further particularly intended or designed to form Test device (PM + M1; PM + M1 + ME) , that is, to be inserted (instead of the electronic vibration module M2) into the basic module M1 and detachably mechanically connected to the basic module M1 such that the carrier element 41 and the first test element 42 are placed within the chamber 11+; in particular, in the same manner as the electronic vibration module M2, or in such a way that the test module PM is locked in the basic module M1 or immovable. In particular, the test module PM is further configured to be installed in the basic module M1 such that the first test element 42 is held at a first test position P1 predefined by the first electrical coil 12 of the basic module, or corresponding to the above-mentioned first installation position, and, for example, further such that the first test element 42 held at the first test position P1 has a predefined orientation and / or predefined minimum distance from the first electrical coil 12, and / or the imaginary longitudinal axis of the first test element is aligned with or extends parallel to the imaginary longitudinal axis of the first electrical coil 12. In the case where the test element 42 has an electrical coil, the test element 42 can, for example, form a transformer together with the electrical coil 12 of the basic module M1, and in another case where the test element 42 has a permanent magnet, the test element 42 can also form, for example, a magnetic coil together with the electrical coil 12 of the basic module M1. To support the correct installation of the test module PM into the basic module M1, the test module PM can also have guiding structures or elements corresponding to or corresponding to the above-mentioned guiding structures or elements of the electronic vibration module M2 of the basic module M1.
[0073] In particular, for the case where the above-described basic module M1 has a number of electric coils - for example, at least coil 14 - the test module PM can further have, in a corresponding manner: at least one test element 44, which is mechanically connected to the carrier element 41 and is, for example, identical and / or spaced apart from the first test element 42 in terms of structure and / or function; a second test element for generating and / or detecting a magnetic field; furthermore, it can also have at least one third test element 46 for generating and / or detecting a magnetic field, which is mechanically connected to the carrier element 41 and is, in particular, identical and / or spaced apart from the first test element and / or the second test element in terms of structure and / or function. In addition, the test module PM can be configured to be inserted into the first basic module M1 and detachably mechanically connected thereto, such that each of the above-described test elements is placed within the chamber 11+, for example, such that the second test element 44 is held in a second test position, which is predetermined with respect to the orientation and / or minimum distance of the second electric coil 14, and / or is spaced apart from the first test position P1, and / or corresponds to the above-described second mounting position, and / or such that the imaginary longitudinal axis of the second test element 44 and the imaginary longitudinal axis of the second electric coil 14 are aligned with each other or extend parallel to each other.
[0074] In particular, for the above case, where the basic module M1 together with the measurement system electronics ME is configured to be able to read the identification element 28 of the electronic vibration module M2, the test module can further include at least one identification element 48, in particular carrying information related to the test module or information for identifying the test module, which is mechanically connected to the carrier element to simplify the commissioning of the test device thus formed, such as a barcode label, a QR code label, or a radio tag (RFID TAG), and furthermore, the measurement system electronics ME can also be configured to read the information carried by the identification element 48 of the test module PM, in particular to evaluate it, for example, in order to verify whether the test module PM is compatible with the basic module M1 and / or the measurement system electronics ME or whether it is authorized to form a test device.
[0075] Figure 4A test module 41 is shown, which is substantially similar to or designed identically to the electronic vibration module according to the invention. The pipes 31 and 32 are configured to carry a medium whose mass flow rate, volume flow rate, density, and / or viscosity are determined. The first test element 42, in the form of a permanent magnet, forms a coil drive system in combination with the first electric coil of the basic module, via which the pipe 31 can be set into mechanical oscillation. The second test element 44 and the third test element 46 are also provided on the carrier element 41. These two test elements, in combination with the second or third electric coil, form a coil sensor system configured to detect the mechanical oscillation of the pipe 31. The test module is a pre-calibrated (gold standard) electronic vibration module, with which the basic module and / or the electronic components of the measurement system can be checked using at least one measured value determined by the electronic components of the measurement system, as well as a reference value associated therewith and / or at least one threshold value predetermined therefor.

The illustrated embodiment exactly includes two substantially parallel planar plates 51a, 51b, with three test elements provided on each planar plate.
[0078] Figure 7a -d shows four embodiments of the test module, which are designed such that when used for the basic module, during measurement, the mass flow is simulated, or the phase difference between the two measurement signals of at least two sensor systems is detected. In the embodiment according to Figure 7a , an asymmetric weight distribution is achieved by providing plates of different lengths. The plate 51a has a length l1, and the plate 51b has a length l2. The length l1 is different from the length l2. In the illustrated embodiment, the length l1 is greater than the length l2. The structure of the test elements is substantially the same.

In the illustrated embodiment, this is achieved by the different sizes of the test elements (i.e., permanent magnets in this example). The first test element 41 has a significantly smaller diameter than the first test element 41*. The lengths of the plates are substantially the same. The difference in the generated magnetic field strength is at least 5%, particularly at least 15%, and preferably at least 50%.
