Description

Technical Field

[0001] This invention relates to the field of Coriolis mass flow technology, and in particular to a Coriolis mass flow meter with installation angle and wall thickness monitoring functions. Background Technology

[0002] Coriolis mass flow meters offer numerous advantages, including safety, high efficiency, and environmental friendliness, leading to their widespread adoption and application in liquid media monitoring. However, existing Coriolis mass flow meters have stringent installation requirements, such as upright, flag-mounted, and inverted installations, necessitating a perfectly vertical installation posture. Due to limitations in on-site installation conditions, achieving the desired installation results with existing Coriolis mass flow meters is difficult, which to some extent affects the device's detection accuracy.

[0003] Furthermore, after prolonged operation, Coriolis mass flow meters experience losses in the internal media pipelines used to conduct liquid media due to factors such as vibration, media erosion and corrosion. Existing Coriolis mass flow meters often fail to detect these losses. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and defects of the prior art and to provide a Coriolis mass flow meter with installation angle and wall thickness monitoring functions.

[0005] A Coriolis mass flow meter with installation angle and wall thickness monitoring functions includes at least one medium pipeline, at least one excitation module, at least one sensing module, and a signal processing module. The signal processing module is used to control the excitation module to realize the oscillation excitation of the medium pipeline by the excitation module. When the medium passes through the medium pipeline, the vibration information of the medium pipeline will change. The sensing module is used to obtain the oscillation deviation of the medium pipeline so that the signal processing module can analyze the mass flow parameters of the medium based on the oscillation deviation.

[0006] It also includes the installation of an angle monitoring module;

[0007] The installation angle monitoring module is communicatively connected to the signal processing module and is used at least to obtain the actual installation direction of the Coriolis mass flow meter, and / or the direction during installation and the real-time direction change after installation.

[0008] The signal processing module is at least further configured to compensate for the angle deviation of the mass flow parameters of the medium obtained by the Coriolis mass flow meter based on the deviation between the actual installation direction and the preset direction; and / or to record and monitor the actual installation direction of the Coriolis mass flow meter, the real-time direction change after installation, calculate the angle difference between the real-time direction change after installation and the preset direction, and continuously compensate for the angle deviation of the mass flow parameters of the medium.

[0009] Specifically, compensation values ​​corresponding to the changes in mass flow parameters of the Coriolis mass flow meter at different tilt angles are obtained based on the query of the pre-experiment, thereby achieving compensation for the mass flow parameters of the medium.

[0010] The installation angle monitoring module includes at least a MEMS sensor.

[0011] Among them, MEMS sensors include one of accelerometers, gyroscopes, or inclinometers.

[0012] The medium pipeline is equipped with at least one wall thickness monitoring module to determine the health status and lifespan prediction of the Coriolis mass flow meter based on the wall thickness of the medium pipeline, to issue alarms for thinning wall thickness, and to compensate for the mass flow parameters of the medium.

[0013] The wall thickness monitoring module is communicatively connected to the signal processing module and is at least used to emit a measurement signal. The measurement signal penetrates the outer wall of the medium pipeline from the emission point and reaches the interface between the medium pipeline and the medium. The measurement signal is reflected at the interface between the medium pipeline and the medium to generate a reflected signal. The reflected signal passes through the medium pipeline and is received by the wall thickness monitoring module. The wall thickness monitoring module determines the wall thickness of the medium pipeline based on the time difference between the measurement signal and the reflected signal.

[0014] The signal processing module is also used to obtain the wall thickness of the medium pipeline, compare it with the original wall thickness of the medium pipeline, determine the instrument health status and predict the service life of the Coriolis mass flow meter, perform wall thickness reduction alarm, and compensate for wall thickness deviation of the mass flow parameters of the medium.

[0015] The method of triggering a wall thickness reduction alarm includes setting a wall thickness alarm threshold. When the actual wall thickness threshold is detected to be lower than the wall thickness alarm threshold, an alarm is triggered.

[0016] The wall thickness monitoring module includes one of an ultrasonic wall thickness monitoring module, an electromagnetic induction wall thickness monitoring module, or an eddy current wall thickness monitoring module.

[0017] The wall thickness monitoring module includes an ultrasonic probe, which may be an integrated transceiver ultrasonic probe or a separate transceiver ultrasonic probe.

[0018] The wall thickness monitoring module is installed at a non-vibration part of the medium pipeline, in direct contact with the medium pipeline, or installed outside the vibration part of the medium pipeline, in a non-contact arrangement with the medium pipeline.

[0019] The Coriolis mass flow meter also includes a temperature monitoring module;

[0020] The temperature detection module is installed on the medium pipeline and is communicatively connected to the signal processing module, and is used at least to acquire the temperature information of the medium pipeline.

[0021] The signal processing module is at least further configured to compensate for the wall thickness of the medium pipeline measured by the wall thickness monitoring module based on the temperature information of the medium pipeline to obtain a calibrated wall thickness, and to judge the instrument health status and predict the service life of the Coriolis mass flow meter, alarm for wall thickness reduction, and compensate for wall thickness deviation of the mass flow parameters of the medium based on the comparison between the calibrated wall thickness and the original wall thickness of the medium pipeline.

[0022] The Coriolis mass flow meter also includes a display module;

[0023] The display module is communicatively connected to the signal processing module and is at least used to display, under the control of the signal processing module, the installation process direction of the Coriolis mass flow meter, the actual installation direction, the real-time direction change after installation and / or the angle difference between the actual installation direction and the preset direction, the thickness of the medium pipeline, the temperature of the medium pipeline, the alarm signal for reduced wall thickness, and the mass flow parameters of the compensated medium.

[0024] The Coriolis mass flow meter of the present invention includes an installation angle monitoring module, which is used to acquire at least the installation direction of the Coriolis mass flow meter during installation, and / or the actual installation direction and the real-time direction change after installation; and a signal processing module, which, based on the deviation between the real-time direction change after installation and a preset direction, performs angle deviation compensation on the mass flow parameters of the medium obtained from the signal processing module, and / or records and monitors the actual installation direction and the real-time direction change after installation, calculates the angle difference between the real-time direction change after installation and the preset direction, and continuously performs angle deviation compensation on the mass flow parameters of the medium. This enables angle deviation compensation of mass flow based on different directions of the flow meter, thereby improving the measurement accuracy of the Coriolis mass flow meter to a certain extent.

[0025] The Coriolis mass flow meter of the present invention, by incorporating a wall thickness monitoring module, is at least used to emit a measurement signal. The wall thickness of the medium pipeline is determined based on the time difference between the measurement signal and the reflected signal. A signal processing module obtains the wall thickness of the medium pipeline and compares it with the original wall thickness of the medium pipeline to determine the instrument's health status and predict its service life. It also provides alarms for thinner wall thickness and wall thickness deviation compensation for mass flow parameters when the wall thickness is lower than the monitored thickness. This allows for more accurate wall thickness data of the medium pipeline and enables the determination of the medium pipeline's health status, life prediction, and alarms for thinner wall thickness. This benefits users by allowing them to understand the instrument's health status and predict its service life. Furthermore, it enables wall thickness deviation compensation for mass flow based on wall thickness, thereby further improving the measurement accuracy of the Coriolis mass flow meter to a certain extent.

[0026] The Coriolis mass flow meter of the present invention acquires the temperature information of the medium pipeline through a temperature detection module; the signal processing module compensates for the wall thickness of the medium pipeline measured by the wall thickness monitoring module based on the temperature information of the medium pipeline to obtain a calibrated wall thickness. By comparing the calibrated wall thickness with the original wall thickness of the medium pipeline, the instrument health status and service life prediction of the Coriolis mass flow meter are judged, and wall thickness deviation compensation is performed for the mass flow parameters of the medium when the wall thickness is too small or lower than the monitored wall thickness. This results in more accurate measurement data of the Coriolis mass flow meter, and more accurate judgment of the instrument health status and prediction of the service life of the Coriolis mass flow meter.

[0029] Figure 3 This is a schematic diagram of a Coriolis mass flow meter with installation angle and wall thickness monitoring functions according to the third embodiment of the present invention. Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0031] like Figure 1As shown in the figure, a Coriolis mass flow meter with installation angle and wall thickness monitoring functions according to an embodiment of the present invention includes at least one medium pipeline, at least one excitation module, at least one sensing module, and a signal processing module. The signal processing module is used to control the excitation module to realize the oscillation excitation of the medium pipeline by the excitation module. When the medium passes through the medium pipeline, the vibration information of the medium pipeline will change. The sensing module is used to obtain the oscillation deviation of the medium pipeline so that the signal processing module can analyze the mass flow parameters of the medium based on the oscillation deviation. The medium pipeline includes an inlet and an outlet. If there are multiple medium pipelines, the multiple medium pipelines can share the inlet and outlet. The medium pipeline contains flowing medium. The excitation module generally includes an excitation coil and a magnet. When the current flow direction in the excitation coil changes, the polarity of the excitation coil will change accordingly, which is manifested as the excitation coil and the magnet attracting or repelling each other. The oscillation excitation of the medium pipeline can be realized by controlling the frequency of the change of the current flow direction in the excitation coil through the signal processing module.

[0032] The Coriolis mass flow meter also includes an installation angle monitoring module and a display module;

[0033] An installation angle monitoring module is connected to the signal processing module to acquire, at least, the actual installation direction of the Coriolis mass flow meter, and / or the direction during installation and the real-time direction change after installation. The signal processing module is also used to compensate for the angle deviation of the mass flow parameters of the medium obtained from the actual installation direction of the Coriolis mass flow meter based on the deviation between the actual installation direction and the preset direction. Furthermore, the module records the actual installation direction of the Coriolis mass flow meter and the real-time direction change after installation, calculates the angle difference between the real-time direction change after installation and the preset direction, and continuously compensates for the angle deviation of the mass flow parameters of the medium.

[0034] The installation process direction refers to the change of the tilt angle of the Coriolis mass flow meter in different dimensions of three-dimensional space during the installation process. The actual installation direction refers to the instantaneous tilt angle of the Coriolis mass flow meter in different dimensions of three-dimensional space after installation. The real-time direction change after installation refers to the change of the tilt angle of the Coriolis mass flow meter in different dimensions of three-dimensional space due to external forces during normal measurement operation after installation.

[0035] In the above technical solution, when compensating for the angular deviation of the mass flow rate parameter of the medium, the compensation value corresponding to the change of mass flow rate parameter of the Coriolis mass flow meter at different tilt angles can be obtained based on the query of the pre-experiment. This achieves the compensation of the mass flow rate parameter of the medium. In actual application, the user can obtain the changes of mass flow rate and other parameters of the Coriolis mass flow meter at different tilt angles based on the pre-experiment, for example, in the form of parameter comparison table, characteristic formula, characteristic curve, etc. Then, in actual application, the user can directly query the corresponding compensation value from the parameter comparison table, characteristic formula, characteristic curve, etc. based on different tilt angles, and finally achieve the angular deviation compensation of the mass flow rate and other parameters of the medium.

[0036] The Coriolis mass flow meter of the present invention includes an installation angle monitoring module, which is used to acquire at least the actual installation direction of the Coriolis mass flow meter, and / or the direction during installation and the real-time direction change after installation; and a signal processing module, which, based on the deviation between the actual installation direction and a preset direction of the Coriolis mass flow meter, performs angle deviation compensation on the mass flow parameters of the medium obtained from the signal processing module, and / or records and monitors the actual installation direction and the real-time direction change after installation of the Coriolis mass flow meter, calculates the angle difference between the real-time direction change after installation and the preset direction, and continuously performs angle deviation compensation on the mass flow parameters of the medium. This enables angle deviation compensation of mass flow based on different directions of the flow meter, thereby improving the measurement accuracy of the Coriolis mass flow meter to a certain extent.

[0037] In this application, the installation position of the installation angle monitoring module can be at the primary instrument (a module consisting of a medium pipeline, an excitation module, and a sensing module), at the secondary instrument (i.e., a signal processing module), or at other installable positions.

[0038] In some implementations, the signal processing module may include a power supply unit that provides power to all components of the Coriolis mass flow meter for operation. The power supply unit may be powered by a rechargeable battery, a non-rechargeable battery, or an external DC power source, whichever is more specific.

[0039] In some implementations, the mounting angle monitoring module includes at least a MEMS sensor or other available sensors, wherein the MEMS sensor may be one of an accelerometer, a gyroscope, or an inclinometer.

[0040] like Figure 2 As shown, in some implementation schemes, at least one wall thickness monitoring module is provided on the medium pipeline to determine the instrument health status and predict the service life of the Coriolis mass flow meter based on the wall thickness of the medium pipeline, to trigger an alarm for reduced wall thickness, and to compensate for the mass flow parameters of the medium.

[0041] In some implementation schemes, the wall thickness monitoring module, mounted on the Coriolis mass flow meter and communicatively connected to the signal processing module, is at least used to emit a measurement signal. The measurement signal penetrates the outer wall of the medium pipeline from the emission point and reaches the interface between the medium pipeline and the medium. The measurement signal is reflected at the interface between the medium pipeline and the medium, generating a reflected signal. The reflected signal passes through the medium pipeline and is received by the wall thickness monitoring module. The wall thickness monitoring module determines the wall thickness of the medium pipeline based on the time difference between the measurement signal and the reflected signal. The signal processing module is also used at least to acquire the wall thickness of the medium pipeline, compare it with the original wall thickness of the medium pipeline, determine the instrument health status and predict the service life of the Coriolis mass flow meter, perform wall thickness reduction alarm, and compensate for wall thickness deviation in the mass flow parameters of the medium.

[0042] The Coriolis mass flow meter of the present invention, by incorporating a wall thickness monitoring module, is at least used to emit a measurement signal. The wall thickness of the medium pipeline is determined based on the time difference between the measurement signal and the reflected signal. A signal processing module acquires the wall thickness of the medium pipeline and compares it with the original wall thickness of the medium pipeline to determine the instrument health status and predict the service life of the Coriolis mass flow meter. It also provides alarms for wall thickness reduction and wall thickness deviation compensation for mass flow parameters when the wall thickness is lower than the monitored thickness. This allows for more accurate wall thickness data and enables the determination of the medium pipeline's health status, lifespan prediction, and alarms for wall thickness reduction. This benefits users by allowing them to understand the instrument health status of the Coriolis mass flow meter and predict its service life. Furthermore, it enables wall thickness deviation compensation for mass flow based on wall thickness, thereby further improving the measurement accuracy of the Coriolis mass flow meter to a certain extent.

[0043] In some implementations, the method of triggering a wall thickness alarm includes setting a wall thickness alarm threshold. When the actual wall thickness threshold is detected to be lower than the wall thickness alarm threshold, an alarm is triggered. Wall thickness monitoring can determine the health status and lifespan prediction of the mass flow meter. For example, based on the monitored wall thickness change data and change rate, the wall thickness change can be predicted, thereby achieving lifespan prediction and health status monitoring.

[0044] For example, when compensating for wall thickness deviation in the mass flow rate parameter of a medium, in practical applications, users can obtain the changes in parameters such as mass flow rate of the Coriolis mass flow meter under different wall thicknesses based on pre-experiments, such as in the form of parameter comparison tables, characteristic formulas, characteristic curves, etc. Then, in practical applications, users can directly look up the corresponding compensation value from the parameter comparison tables, characteristic formulas, characteristic curves, etc., based on different wall thicknesses, and finally realize the wall thickness deviation compensation of the monitored wall thickness for parameters such as mass flow rate of the medium.

[0045] In some implementations, the wall thickness monitoring module includes one of the following: ultrasonic wall thickness monitoring module, electromagnetic induction wall thickness monitoring module, or eddy current wall thickness monitoring module. That is, wall thickness monitoring can be carried out using available monitoring methods under current technology, such as using ultrasonic technology to monitor wall thickness, using eddy current technology to monitor wall thickness, or using electromagnetic induction technology to monitor wall thickness. Other wall thickness monitoring technologies are also possible and are not limited to these.

[0046] In a preferred embodiment, the wall thickness monitoring module includes an ultrasonic probe that uses ultrasonic technology to monitor the wall thickness. The ultrasonic probe may be an integrated transceiver ultrasonic probe or a separate transceiver ultrasonic probe, etc., and is not limited to any specific type.

[0047] To obtain stable wall thickness measurement data, preferably, the wall thickness monitoring module is installed on a non-vibrating part of the medium pipeline, directly contacting the medium pipeline, or installed on the outside of a vibrating part of the medium pipeline, without direct contact with the medium pipeline. For example, it can be installed on the outside of the medium pipeline via a bracket. When installed on a vibrating part, the wall thickness monitoring module directly contacts the medium pipeline for wall thickness detection. If installed on a vibrating part, the wall thickness monitoring module does not directly contact the medium pipeline, thus not affecting the vibration of the medium pipeline. Furthermore, the wall thickness of the medium pipeline can be periodically checked when not in operation. For example, when periodically checking the wall thickness of the medium pipeline, the same medium is poured into the medium pipeline each time, and the results of each test are compared with the initial test results (e.g., comparing the signal amplitude) to determine the wall thickness of the medium pipeline.

[0048] like Figure 3 As shown, in some implementations, the Coriolis mass flow meter further includes a temperature monitoring module; the temperature detection module is installed on the medium pipeline and is communicatively connected to the signal processing module, and is at least used to acquire the temperature information of the medium pipeline; the signal processing module is at least also used to compensate the wall thickness of the medium pipeline measured by the wall thickness monitoring module according to the temperature information of the medium pipeline to obtain a calibrated wall thickness (i.e., an accurate wall thickness), and to judge the instrument health status and predict the service life of the Coriolis mass flow meter by comparing the calibrated wall thickness with the original wall thickness of the medium pipeline, and to perform wall thickness deviation compensation for the mass flow parameters of the medium.

[0049] Since the transmission speed of the measurement signal and reflected signal emitted by the wall thickness monitoring module in the outer wall of the medium pipeline is affected by temperature, the temperature of the medium pipeline can be obtained by the temperature detection module, and the aforementioned transmission speed can be corrected by the temperature, thereby obtaining the accurate wall thickness.

[0050] For example, when compensating for wall thickness deviation in the mass flow rate parameter of a medium, in practical applications, users can obtain the changes in parameters such as mass flow rate of the Coriolis mass flow meter under different wall thicknesses based on pre-experiments, such as in the form of parameter comparison tables, characteristic formulas, characteristic curves, etc. Then, in practical applications, users can directly look up the corresponding compensation value from the parameter comparison tables, characteristic formulas, characteristic curves, etc., based on different wall thicknesses, and finally realize the wall thickness deviation compensation of the monitored wall thickness for parameters such as mass flow rate of the medium.

[0051] In summary, the Coriolis mass flow meter of the present invention, by incorporating a temperature detection module to acquire temperature information of the medium pipeline, and a signal processing module, by compensating the wall thickness of the medium pipeline measured by the wall thickness monitoring module based on the temperature information of the medium pipeline to obtain a calibrated wall thickness, and by comparing the calibrated wall thickness with the original wall thickness of the medium pipeline, performs instrument health status judgment and service life prediction of the Coriolis mass flow meter, wall thickness reduction alarm, and wall thickness deviation compensation for the mass flow parameters of the medium when the wall thickness is lower than the monitored wall thickness, can obtain more accurate measurement data of the Coriolis mass flow meter, and at the same time, the judgment of the instrument health status and the prediction of the service life of the Coriolis mass flow meter are more accurate.

[0052] In some implementation schemes, such as Figure 1 , Figure 2 , Figure 3 As shown, the Coriolis mass flow meter also includes a display module; the display module is communicatively connected to the signal processing module and is used, at least under the control of the signal processing module, to display the installation process direction, actual installation direction, real-time direction change after installation and / or the angle difference between the actual installation direction and the preset direction, the thickness of the medium pipeline, the temperature of the medium pipeline, the alarm signal for reduced wall thickness, and the mass flow parameters of the compensated medium. This facilitates the intuitive display of relevant monitoring parameters to the user or the output of alarm information, allowing the user to promptly grasp the status of the Coriolis mass flow meter.

[0053] As can be seen from the above description, the Coriolis mass flow meter of the present invention can monitor at least the installation process direction, actual installation direction, real-time direction change after installation, and / or the angle difference between the actual installation direction and the preset direction, and / or the thickness and temperature of the medium pipeline. Based on the deviation between the actual installation direction and the preset direction of the Coriolis mass flow meter, it compensates for the angle deviation of the mass flow parameters of the medium obtained from the measurement. It also records and monitors the actual installation process direction and the real-time direction change after installation, calculates the angle difference between the real-time direction change after installation and the preset direction, continuously compensates for the angle deviation of the mass flow parameters of the medium, and / or obtains the wall thickness of the medium pipeline. The original wall thickness of the medium pipeline is compared to determine the instrument health status and lifespan prediction of the Coriolis mass flow meter. Wall thickness reduction alarms and wall thickness deviation compensation for mass flow parameters below the monitored wall thickness are implemented. Alternatively, based on the temperature information of the medium pipeline, the wall thickness measured by the wall thickness monitoring module is compensated to obtain a calibrated wall thickness. The calibrated wall thickness is then compared with the original wall thickness of the medium pipeline to determine the instrument health status and lifespan prediction of the Coriolis mass flow meter, and wall thickness reduction alarms and wall thickness deviation compensation for mass flow parameters below the monitored wall thickness are implemented. This improves the detection accuracy of the Coriolis mass flow meter and helps users understand the instrument health status and predict the lifespan of the Coriolis mass flow meter.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

Thus, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within the invention.
