[0001] This application relates to the field of flow meter measurement technology, and in particular to a transducer position adjustment method for an ultrasonic flow meter and an ultrasonic flow meter. Background Technology

[0002] The installation direction of the transducer of an ultrasonic flow meter is a crucial step in ensuring its measurement accuracy. If the direction is reversed, it may cause the flow rate to be displayed as negative or the measurement value to be seriously inaccurate.

[0003] In existing technologies, if the transducer is found to be in the wrong position after installation, it needs to be disassembled and redeployed to install the transducer correctly, which leads to problems such as low maintenance efficiency, high fault tolerance, and unstable quality. Summary of the Invention

[0004] The purpose of this application is to provide a method for adjusting the transducer position of an ultrasonic flow meter, as well as the ultrasonic flow meter itself, to achieve transducer position adjustment without disassembly, thereby improving maintenance efficiency, fault tolerance, and stability.

[0013] In one possible embodiment, the first transducer and the second transducer are detachably provided with position markers, which are used to indicate whether the transducer is an upstream transducer or a downstream transducer.

[0014] After changing the target velocity calculation module to the velocity calculation module corresponding to the case where the first transducer and the second transducer are in a second relative position, the method further includes:

[0015] The third information is displayed, which prompts the user to swap the position markers on the first transducer and the second transducer.

[0016] In a second aspect of this application, a transducer position adjustment device for an ultrasonic flow meter is provided, applied to the ultrasonic flow meter, the ultrasonic flow meter including a transducer pair consisting of a first transducer and a second transducer, the device comprising:

[0017] The measurement module is used to input the ultrasonic signal detected by the transducer pair to the target flow velocity calculation module when the transducer pair is installed on the pipeline, so as to obtain and display the flow rate of the fluid in the pipeline; the target flow velocity calculation module is initially the flow velocity calculation module corresponding to the first transducer and the second transducer being in a first relative position;

[0018] An adjustment module is used to, in response to a position adjustment command for the displayed flow input, change the target flow rate calculation module to the flow rate calculation module corresponding to the case where the first transducer and the second transducer are in a second relative position.

[0019] In one possible embodiment, the device further includes a verification module for driving the measurement module to return to the step of inputting the ultrasonic signal detected by the transducer pair to the target flow velocity calculation module to obtain and display the flow rate of the fluid in the pipe when the transducer pair is set on the pipe, after the target flow velocity calculation module is changed to the flow velocity calculation module corresponding to the case where the first transducer and the second transducer are in a second relative position, until the flow rate is positive.

[0020] In one possible embodiment, the adjustment module changes the target flow rate calculation module to the flow rate calculation module corresponding to the case where the first transducer and the second transducer are in a second relative position, including:

[0021] The display position configuration interface shows first information and second information in different styles.

[0024] The device further includes a prompting module for displaying third information after the target flow rate calculation module is changed to the flow rate calculation module corresponding to the first transducer and the second transducer being in a second relative position.

The target flow velocity calculation module can be changed to the flow velocity calculation module corresponding to the first transducer and the second transducer being in different relative positions, thereby indirectly achieving the adjustment of the transducer position. Furthermore, the adjustment of the transducer position does not require disassembly and redeployment of the transducers, thus improving maintenance efficiency, fault tolerance, and stability.

[0033] Of course, implementing any product or method of this application does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0048] See Figure 1 , Figure 1 The diagram shown is a first flowchart of a transducer position adjustment method for an ultrasonic flow meter provided in this application. This method is applied to an ultrasonic flow meter, which includes a transducer pair consisting of a first transducer and a second transducer. The method includes:

[0049] Step S101: With the transducer pair installed on the pipeline, the ultrasonic signal detected by the transducer pair is input to the target flow velocity calculation module to obtain and display the flow rate of the fluid in the pipeline.

[0050] The target flow velocity calculation module is initially the flow velocity calculation module corresponding to the first transducer and the second transducer being in the first relative position.

[0051] Step S102, in response to the position adjustment command for the displayed flow input, the target flow rate calculation module is changed to the flow rate calculation module corresponding to the case where the first transducer and the second transducer are in a second relative position.

[0052] By using this embodiment, the target flow rate calculation module can be changed to the flow rate calculation module corresponding to the case where the first transducer and the second transducer are in different relative positions, thereby indirectly realizing the adjustment of the transducer position. Moreover, the adjustment of the transducer position does not require disassembly and redeployment of the transducer, thereby improving maintenance efficiency, fault tolerance and stability.

[0053] Steps S101 to S102 will be explained below:

[0054] In step S101, after the transducers are installed on the pipe, the first and second transducers will respectively transmit ultrasonic signals to each other. The ultrasonic signals are received by the other transducer after passing through the pipe. Based on the time when the first and second transducers transmit and receive the ultrasonic signals, the following times can be obtained: the time t1 for the ultrasonic signal to travel from the first transducer to the second transducer is 2, and the time t2 for the ultrasonic signal to travel from the second transducer to the first transducer is 1.

[0055] It is understandable that when the fluid in the pipe is stationary, since the distance the ultrasonic signal travels from the first transducer to the second transducer is equal to the distance it travels from the second transducer to the first transducer, if the fluid in the pipe is stationary, then t1→2 should be equal to t2→1.

[0056] When the fluid in the pipe is not stationary, for example, assuming the fluid flows from the first transducer to the second transducer (i.e., the first transducer is upstream of the second transducer), the ultrasonic signal emitted by the first transducer to the second transducer will be accelerated because it flows in the same direction as the fluid, thus decreasing t1→2. Conversely, the ultrasonic signal emitted by the second transducer to the first transducer will be decelerated because it flows in the opposite direction to the fluid, thus increasing t2→1. The magnitude of the decrease in t1→2 and the magnitude of the increase in t2→1 depend on the fluid flow rate. Therefore, t2→1 - t1→2 can be calculated, and the fluid flow rate can be estimated based on the difference. If the mapping relationship between the difference and the flow rate is denoted as f(·), and the flow rate is denoted as Q, then the flow rate can be calculated according to formula (1):

[0057] Q= f(t2→1-t1→2) … (1)

[0058] Similarly, if the fluid flows from the second transducer to the first transducer (i.e., the first transducer is downstream of the second transducer), t1→2 - t2→1 can be calculated, and the fluid velocity can be deduced based on the difference. That is, the flow rate at this time can be calculated according to formula (2):

[0059] Q= f(t1→2-t2→1)…(2)

[0060] It can be seen that if the first relative position is that the first transducer is upstream of the second transducer, the flow rate should be calculated using formula (1), while if the first relative position is that the first transducer is downstream of the second transducer, the flow rate should be calculated using formula (2). That is to say, if the first relative position is that the first transducer is upstream of the second transducer, the velocity calculation module corresponding to the first and second transducers being in the first relative position (i.e., the initial target velocity calculation module) calculates the flow rate of the fluid in the pipe using the above formula (1). If the first relative position is that the first transducer is downstream of the second transducer, the velocity calculation module corresponding to the first and second transducers being in the first relative position (i.e., the initial target velocity calculation module) calculates the flow rate of the fluid in the pipe using the above formula (2). For ease of description, the velocity calculation module corresponding to the first and second transducers being in the first relative position will be referred to as the velocity calculation module corresponding to the first relative position. Similarly, the velocity calculation module corresponding to the second relative position of the first transducer and the second transducer is simply referred to as the velocity calculation module corresponding to the second relative position.

[0061] The flow velocity calculation module corresponding to the first relative position and the flow velocity calculation module corresponding to the second relative position can be either a software module or a hardware module deployed in the ultrasonic flow meter.

[0062] In step S102, the second relative position is the opposite of the first relative position. Specifically, if the first relative position is that the first transducer is upstream of the second transducer, then the second relative position is that the first transducer is downstream of the second transducer; if the first relative position is that the first transducer is downstream of the second transducer, then the second relative position is that the first transducer is upstream of the second transducer.

[0063] The target flow rate calculation module can be replaced by adjusting the input position of the displayed flow rate. Users can input the position adjustment command whenever they want to replace the target flow rate calculation module.

[0064] In one possible implementation, the position adjustment command is input when the displayed flow rate is negative. In this embodiment, based on physics, the aforementioned f(·) is an odd function, with a positive value in the feasible region (0, +∞) and a negative value in the feasible region (-∞, 0). For example, the expression for f(·) can be as shown in formula (3):

[0065] … (3)

[0066] Where x is the independent variable of f(·), C is the speed of sound in the fluid, L is the length of the propagation path of the ultrasonic signal in the fluid, and θ is the angle between the propagation path and the axis of the pipe.

[0067] For the case where the relative position corresponding to the target velocity calculation module is that the first transducer is upstream of the second transducer, the flow rate is calculated according to the aforementioned formula (1). If the first transducer is indeed upstream of the second transducer, then t2→1 is greater than t1→2, and therefore the flow rate is positive. However, if the first transducer is actually downstream of the first transducer, then t2→1 is less than t1→2, and therefore the flow rate is negative. Since the target velocity calculation module is initially the velocity calculation module corresponding to the first relative position, the initial relative position corresponding to the target velocity calculation module is the first relative position.

[0068] Similarly, for the case where the relative position of the target flow velocity calculation module is that the first transducer is downstream of the second transducer, the flow rate is calculated according to the aforementioned formula (2). If the first transducer is indeed downstream of the second transducer, then t1→2 is greater than t2→1, so the flow rate is positive. However, if the first transducer is actually upstream of the first transducer, then t1→2 is less than t2→1, so the flow rate is negative.

[0069] As can be seen, when the relative position of the target flow rate calculation module is inconsistent with the actual relative position, the calculated flow rate will be negative. Since the position adjustment command is input when the displayed flow rate is negative, it can be assumed that the relative position of the target flow rate calculation module is inconsistent with the actual relative position upon receiving the command. In this case, the relative position of the target flow rate calculation module is changed by replacing it with the flow rate calculation module corresponding to the second relative position, thus aligning the changed relative position with the actual relative position. In other words, in the example where the position adjustment command is input when the displayed flow rate is negative, changing the target flow rate calculation module will ensure that its relative position matches the actual relative position, allowing for accurate flow rate calculation subsequently based on the changed target flow rate calculation module.

[0070] In another possible implementation, the location adjustment command can also be entered when the displayed traffic is positive.

[0071] As can be seen from the foregoing description of steps S101 to S102, the transducer position adjustment method of the ultrasonic flow meter provided in this application controls the flow calculation mode through the target flow velocity calculation module, and adaptively adjusts the flow calculation mode by changing the target flow velocity calculation module through input position adjustment command. This avoids adjusting the actual position of the transducer, thus eliminating the need to disassemble and redeploy the transducer, effectively improving maintenance efficiency, fault tolerance and stability.

[0072] In one possible embodiment, the target flow rate calculation module is the flow rate calculation module corresponding to the relative position recorded in the configuration file. The initial relative position recorded in the configuration file is designated as the first relative position, and correspondingly, the target flow rate calculation module is initially the flow rate calculation module corresponding to the first relative position.

[0073] The configuration file can be stored locally on the ultrasonic flow meter or on other electronic devices that have established a communication connection with the ultrasonic flow meter. For the sake of convenience, the following description will only take the example of storing the configuration file locally on the ultrasonic flow meter.

[0074] The relative positions initially recorded in the configuration file are pre-written. Furthermore, when the ultrasonic flowmeter leaves the factory, the relative positions can be randomly assigned to the configuration file, or they can be assigned based on the respective categories of the first and second transducers. Specifically, if the first transducer is an upstream transducer (TU) and the second transducer is a downstream transducer (TD), then the configuration file contains a relative position indicating that the first transducer is upstream of the second transducer; conversely, if the first transducer is a downstream transducer and the second transducer is an upstream transducer, then the configuration file contains a relative position indicating that the first transducer is downstream of the second transducer.

[0075] In this embodiment, the target flow rate calculation module is modified by changing the relative position recorded in the configuration file. Specifically, in response to a position adjustment command, the relative position recorded in the configuration file is changed, and the modified relative position recorded in the configuration file is recorded as the second relative position, thereby changing the target flow rate calculation module to the flow rate calculation module corresponding to the second relative position.

[0076] The calculations of different flow rate calculation modules are not limited to the above formulas. Those skilled in the art can also fit the formulas based on the measured results, or derive the formulas by combining other theories with the measured results.

[0077] See Figure 2 , Figure 2 The diagram shown is a second flowchart illustrating the transducer position adjustment method for the ultrasonic flowmeter provided in this application. Compared to... Figure 1 The example shown adds step S103. Figure 2 In the example shown, the methods include:

[0078] Step S101: With the transducer pair installed on the pipeline, the ultrasonic signal detected by the transducer pair is input to the target flow velocity calculation module to obtain and display the flow rate of the fluid in the pipeline.

[0079] The target flow velocity calculation module is initially the flow velocity calculation module corresponding to the first transducer and the second transducer being in the first relative position.

[0080] Step S102, in response to the position adjustment command for the displayed flow input, the target flow rate calculation module is changed to the flow rate calculation module corresponding to the case where the first transducer and the second transducer are in a second relative position.

[0081] Step S103: Return to step S101 until the flow rate is positive.

[0082] Steps S101 to S102 can be found in the foregoing. Figure 1 The relevant explanations will not be repeated here. The following text only addresses... Figure 2 The newly added step S103 is explained below:

[0083] In step S103, as described in the previous step S102, if changing the target flow rate calculation module can make the relative position of the changed target flow rate calculation module consistent with the actual relative position, then the flow rate can be accurately calculated based on the changed target flow rate calculation module.

[0084] However, in some cases, the relative position corresponding to the target flow rate calculation module after modification may still be inconsistent with the actual relative position. For example, the user may input a position adjustment command when the flow rate is positive, or a negative value may be caused by transient backflow in the pipeline. To verify whether the relative position corresponding to the target flow rate calculation module after modification is consistent with the actual relative position, Figure 2 In the example shown, after changing the relative position corresponding to the target flow rate calculation module, the process returns to step S101. If the recalculated flow rate is positive at this time, it is considered that the relative position corresponding to the target flow rate calculation module after the change is consistent with the actual relative position.

[0085] It is evident that the selection Figure 2 The example shown improves the accuracy of transducer position adjustment by verifying the relative position of the modified target velocity calculation module.

[0086] See Figure 3 , Figure 3 The diagram shown is a second flowchart illustrating the transducer position adjustment method for the ultrasonic flowmeter provided in this application. Compared to... Figure 1 The example shown refines step S102 into steps S1021 to S1022. Figure 3 In the example shown, the methods include:

[0087] Step S101: With the transducer pair installed on the pipeline, the ultrasonic signal detected by the transducer pair is input to the target flow velocity calculation module to obtain and display the flow rate of the fluid in the pipeline.

[0088] The target flow velocity calculation module is initially the flow velocity calculation module corresponding to the first transducer and the second transducer being in the first relative position.

[0089] Step S1021: In response to the position adjustment instruction for the displayed traffic input, the position configuration interface is displayed.

[0090] The position configuration interface displays first information and second information in different styles. The first information is used to indicate that the first transducer and the second transducer are in a first relative position and the first transducer and the second transducer are in a second relative position.

[0091] Step S1022: In response to the selection instruction for the second information, the target flow rate calculation module is changed to the flow rate calculation module corresponding to the case where the first transducer and the second transducer are in a second relative position.

[0092] Step S101 can be referred to the above. Figure 1 The relevant explanations will not be repeated here. The following only explains steps S1021 to S1022:

[0093] In step S1021, the first relative position is the relative position corresponding to the current target flow rate calculation module, and the second relative position is the relative position corresponding to the modified target flow rate calculation module. By displaying the first and second information in different styles, the user can know the relative position corresponding to the current target flow rate calculation module and the relative position corresponding to the modified target flow rate calculation module, so as to help the user determine whether the target flow rate calculation module needs to be modified.

[0094] For example, assuming the first transducer is the upstream transducer, the second transducer is the downstream transducer, and the relative position of the current target velocity calculation module is: the upstream transducer is located upstream, then the configuration interface can be as follows: Figure 5d As shown, Figure 5dIn the example shown, "TU is upstream" is the first piece of information, and "TU is downstream" is the second piece of information. Figure 5d In the example shown, the first and second information are distinguished by adding a "√" after the first information. In other possible examples, the first and second information could also be distinguished by changing the font, font size, etc.

[0095] In step S1022, since the first information and the second information have been displayed in different styles in step S1021 so that the user can clearly determine whether the target flow rate calculation module needs to be changed, if the user still selects the second information in this case, it can be assumed that the user has determined that the target flow rate calculation module needs to be changed. Therefore, in response to the selection instruction for the second information, the target flow rate calculation module is changed to the flow rate calculation module corresponding to the second relative position.

[0096] Select Figure 3 The example shown demonstrates how displaying the first and second information in different styles allows users to clearly determine whether the target flow rate calculation module needs to be changed before making any changes, thus reducing the possibility of user errors.

[0097] See Figure 4 , Figure 4 The diagram shown is a third flowchart of the transducer position adjustment method for the ultrasonic flowmeter provided in this application, compared to... Figure 1 The example shown adds step S104, and in Figure 4 In the example shown, position markers are detachably mounted on both the first and second transducers. Figure 4 Before explaining the example shown, the location identifier will be explained below:

[0098] There are two types of location markers. The first type indicates that the transducer is an upstream transducer, and the second type indicates that the transducer is a downstream transducer. These two types of location markers have different visual effects so that users can distinguish between upstream and downstream transducers by the location markers. For example, the first type of location marker is printed with the letters "TU", while the second type of location marker is printed with the letters "TD".

[0099] Furthermore, the types of position markers set on the first transducer and the second transducer are different. That is, if the first transducer is set with the first type of position marker, the second transducer should be set with the second type of position marker, and vice versa.

[0100] Furthermore, the position markings can be detachably mounted on the transducer in any way, such as by adhesive, snap-fit, or magnetic attraction, and this application does not impose any limitations on this.

[0101] Please watch it again. Figure 4 The following will be about Figure 4 The methods shown in the example are illustrated, including:

[0102] Step S101: With the transducer pair installed on the pipeline, the ultrasonic signal detected by the transducer pair is input to the target flow velocity calculation module to obtain and display the flow rate of the fluid in the pipeline.

[0103] The target flow velocity calculation module is initially the flow velocity calculation module corresponding to the first transducer and the second transducer being in the first relative position.

[0104] Step S102, in response to the position adjustment command for the displayed flow input, the target flow rate calculation module is changed to the flow rate calculation module corresponding to the case where the first transducer and the second transducer are in a second relative position.

[0105] Step S104: Display the third piece of information.

[0106] The third piece of information is used to prompt the swapping of the position markers on the first and second transducers.

[0107] Steps S101 to S102 can be found in the foregoing. Figure 1 The relevant explanations will not be repeated here. The following only explains step S104:

[0108] In step S104, although the target velocity calculation module and its relative position have been changed, the user may forget the changed relative position. The previously set position identifier may not match the changed relative position. For example, the first transducer might have a first-type position identifier, but the changed relative position of the target velocity calculation module would be downstream of the second transducer (equivalent to the first transducer being the downstream transducer). If the user still relies on the previously set position identifier when distinguishing between upstream and downstream transducers, the distinction will be incorrect.

[0109] And choose Figure 4 The example shown can promptly prompt the user to adaptively swap the position markers after the relative position of the target flow rate calculation module is changed. This allows the user to accurately distinguish the upstream and downstream transducers based on the position markers even if they forget the relative position of the target flow rate calculation module after the change, thus enabling the user to better use the ultrasonic flow meter.

[0110] The transducer position adjustment method of the ultrasonic flowmeter provided in this application has been described above from the perspective of method flow. The following section will provide an exemplary description of the transducer position adjustment method of the ultrasonic flowmeter provided in this application from the perspective of the ultrasonic flowmeter's interface flow. Please refer to [link to relevant documentation]. Figures 5a-5e .

[0111] exist Figures 5a-5e In the example shown, after the ultrasonic flow meter is turned on, it will calculate and display the flow rate according to the aforementioned step S101. The flow rate displayed by the ultrasonic flow meter can be one of two possibilities:

[0112] Possibility 1: such as Figure 5a As shown, the displayed traffic is negative;

[0113] Possibility 2: such as Figure 5b As shown, the displayed traffic is a positive value;

[0114] For example Figure 5b As shown in the previous explanation, the relative position of the target flow velocity calculation module is consistent with the actual relative position, and no further adjustment is required.

[0115] And for such Figure 5a As shown, the relative position of the target velocity calculation module is inconsistent with the actual relative position, requiring adjustment of the transducer position. At this point, the user enters... Figure 5c On the interface shown, after selecting "Transducer Position" and clicking the OK button, you can input the position adjustment command to the ultrasonic flow meter.

[0116] In response to a position adjustment command, the ultrasonic flow meter displays as follows Figure 5d The interface shown corresponds to the first piece of information mentioned above, where "TU is upstream" and "TU is downstream" corresponds to the second piece of information mentioned above. Users in... Figure 5d In the interface shown, select "TU downstream" and click the confirmation button to input the selection command for the second information to the ultrasonic flow meter.

[0117] In response to the selection command, the ultrasonic flow meter changes the target flow rate calculation module (i.e., performs the aforementioned step S102) and displays as shown. Figure 5e The interface shown indicates to the user that the changes to the target flow rate calculation module have been completed, based on the change in the relative position of the module. (User exits) Figure 5e After the interface shown, remeasure the flow rate using the ultrasonic flow meter. The remeasured flow rate should be a positive value; that is, after remeasurement, the ultrasonic flow meter will display as shown. Figure 5b The interface shown.

[0118] Corresponding to Figures 5a-5eThe flowchart of the transducer position adjustment method of the ultrasonic flowmeter provided in this application is shown in the example below. Figure 6 As shown, it includes:

[0119] Step S601: Power on the device.

[0120] Step S602: Obtain the current flow measurement value (taking volumetric flow rate as an example).
