[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0057] The turbine flow sensor testing and analysis method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, the turbine flow sensor 102 is installed on the water flow standard device 100 and then jointly set on the flow measurement system 200 to measure the flow data at a specified flow point within the flow measurement system 200. Alternatively, the turbine flow sensor 102 and the water flow standard device 100 can be respectively set at locations within the flow measurement system 200 where the pipe temperature, pressure, and pipe diameter are the same, which can be considered as the same flow point (i.e., locations with the same volumetric flow rate), to measure the flow data at a specified flow point within the flow measurement system 200. The flow data measured by the turbine flow sensor 102 is transmitted to the intelligent control unit 104. The intelligent control unit 104 acquires the measurement data obtained by the turbine flow sensor 102, analyzes the measurement data, and obtains the test results. The flow measurement system 200 can be a valve cooling or de-icing system, and the water flow standard device 100 can have different diameters. During testing, it can be installed at different measurement points, including different volumetric flow rates within the same pipe or different flow rates within different pipes.

[0058] In one embodiment, such as Figure 2 As shown, a test and analysis method for a turbine flow sensor is provided, which can be applied to... Figure 1 Taking the intelligent control unit 104 as an example, the following steps are included:

[0059] Step 202: Obtain the instrument coefficients obtained by measuring the flow points on water flow standard devices of different diameters using a turbine flow sensor.

[0060] The water standard flow meter is a measuring instrument used in the field of mechanics. It can calibrate, test, prototype, and provide technical services for parameters such as flow rate of liquid flow meters including electromagnetic flow meters, turbine flow meters, ultrasonic flow meters, vortex flow meters, mass flow meters, heat meters, and water meters. In this solution, the water standard flow meter is used to calibrate standard flow rates and assist in the testing and analysis of turbine flow sensors. The instrument coefficient is an inherent parameter of the turbine flow sensor, which can be directly obtained during measurement. It is defined as the number of signal pulses output by the turbine flow sensor when a unit volume of fluid passes through it, and is one of the parameters characterizing the metering characteristics of the turbine flow sensor. The flow point refers to the selected measurement flow point in the measured flow system. The volumetric flow rate at this point depends on the temperature, pressure, and pipe diameter of the pipeline. Flow points within the same pipe at the same temperature, pressure, and diameter can be considered the same flow point, and this also applies to different pipes.

[0061] Specifically, the turbine flow sensor is installed on a water standard flow device to measure the flow rate at a specific point in the system being measured; or the turbine flow sensor and the water standard flow device are positioned at a location equivalent to the same measurement point. The instrument coefficient of the turbine flow sensor based on the water flow standard device is obtained through measurement.

[0062] Furthermore, the flow points selected during measurement can be multiple, and can be any two or more values; the water flow standard devices can be any two or more sets, and each water flow standard device has a different diameter; the number of repeated measurements can be any two or more values, and the number of repeated measurements represents the number of times the turbine flow sensor measures each set of water flow standard devices at each flow point.

[0063] For example, four flow points can be selected for measurement, two sets of water flow standard devices can be used, and the measurement can be repeated six times. That is, at the first flow point, the instrument coefficient of the turbine flow sensor based on the first set of water flow standard devices is measured six times, and then the instrument coefficient of the turbine flow sensor based on the second set of water flow standard devices is measured six times as well. This completes the measurement of the first flow point. The above measurement operation is then performed on the remaining three flow points respectively, thus completing the measurement of four flow points.

[0064] Step 204: Based on the instrument coefficients obtained by the turbine flow sensor on water flow standard devices of different diameters at the same flow point, calculate the average instrument coefficient of the turbine flow sensor under the corresponding diameter water flow standard device.

[0065] Specifically, water flow standard devices have different diameters. Turbine flow sensors are set on water flow standard devices of different diameters to measure the flow points and obtain the instrument coefficients of the same flow point for different diameters. The measurements are repeated at the flow points, and the average of the data sets under the same diameter water flow standard device is taken to obtain the average instrument coefficient of the turbine flow sensor under the corresponding diameter water flow standard device.

[0066] Furthermore, when using a water flow standard device of a certain diameter at the measurement point, repeated measurements are taken to obtain instrument coefficient data, namely k1, k2...k n The average instrument coefficient is then:

[0067]

[0068] In the formula, k is the average instrument coefficient of a turbine flow sensor based on a water flow standard device of a certain diameter at a certain flow point. i Let n represent the instrument coefficient of the turbine flow sensor obtained from the i-th measurement, where n is the total number of measurements.

[0069] Step 206: Calculate the measurement repeatability and the average instrument coefficient of the turbine flow sensor under the corresponding diameter water flow standard device.

[0070] Measurement repeatability refers to the degree of consistency among the results of continuous measurements of the same measurand under the same measurement method, observer, measuring instrument, location, working conditions, and short period of time. Specifically, by setting up water flow standard devices of different diameters at flow points, the average instrument coefficient of the turbine flow sensor under different diameter water flow standard devices can be obtained. The obtained average instrument coefficient is then categorized and calculated according to measurement data obtained from the same flow point and the same water flow standard device, and measurement data obtained from all water flow standard devices at the same flow point. This allows us to obtain measurement repeatability and the average instrument coefficient for the corresponding flow point.

[0071] Furthermore, measurement repeatability is calculated by taking the average instrument coefficient of the turbine flow sensor at the same flow point based on the same diameter water flow standard device, and the average instrument coefficient at the corresponding flow point is calculated by taking the average instrument coefficient of the turbine flow sensor at the same flow point based on different diameter water flow standard devices.

[0072] Step 208: Calculate the comparison control values ​​for each measurement point based on the average instrument coefficient of the turbine flow sensor at different flow points.

[0073] Among them, the comparison control value is an expression of the relationship between the instrument coefficient and the expanded uncertainty of the device. The expanded uncertainty of the device is one of the factory data of the water flow standard device, which represents the error of the water flow standard device caused by production, operation and measurement.

[0074] Specifically, based on the average instrument coefficient of the turbine flow sensor at a certain flow point, the average instrument coefficient of the turbine flow sensor under each set of water flow standard devices at that flow point, and the different expanded uncertainties of different water flow standard devices, the three data constitute the relationship between the instrument coefficient and the expanded uncertainty of the device, and the comparison control value corresponding to each flow point is obtained.

[0075] Step 209: Analyze the performance of the turbine flow sensor based on the average instrument coefficient, measurement repeatability, and comparative control values ​​at each measurement point for the corresponding flow points.

[0076] Specifically, during the test, multiple flow points are selected, and water flow standard devices of different diameters are set up for repeated measurements at each flow point. Based on the multiple values ​​obtained from repeated measurements, the average instrument coefficient, multiple test repeatability, and comparison control values ​​of multiple flow points can be obtained. The average instrument coefficient, measurement repeatability, and comparison control values ​​of the corresponding flow points are numerically analyzed to obtain the performance results of the turbine flow sensor.

[0077] In the above-mentioned test and analysis method for turbine flow sensors, the average instrument coefficient, measurement repeatability, and comparison control values ​​of the corresponding flow points are obtained. Various data are acquired from multiple dimensions and calculated to test the turbine flow sensor, so as to achieve accurate test and analysis of the turbine flow sensor.

[0078] In one embodiment, such as Figure 3 As shown, based on the average instrument coefficient of the turbine flow sensor under the corresponding diameter water flow standard device, the measurement repeatability and the average instrument coefficient of the corresponding flow point are calculated, including:

[0079] Step 302: Calculate the measurement repeatability of the turbine flow sensor based on the average instrument coefficient of the turbine flow sensor under the corresponding diameter water flow standard device and the measured instrument coefficient.

[0080] Specifically, the measurement repeatability formula can be obtained from the measured instrument coefficient data and the average instrument coefficient obtained in Equation 1:

[0081]

[0082] In the formula, δ represents the measurement repeatability of the turbine flow sensor at a certain flow point based on the instrument coefficient of a water flow standard device of a certain diameter.

[0083] Step 304: Average the average instrument coefficient of the turbine flow sensor under different diameter water flow standard devices to obtain the average instrument coefficient of the corresponding flow point.

[0084] Specifically, water flow standard devices of different diameters are set at the flow points to obtain the average instrument coefficient of the turbine flow sensor under the water flow standard devices of different diameters. The average instrument coefficient of the turbine flow sensor under the water flow standard devices of different diameters at the same flow point is then averaged again to obtain the average instrument coefficient of the corresponding flow point.

[0085] Furthermore, from Equation 1, the average instrument coefficient of the turbine flow sensor based on a water flow standard device of a certain diameter at a certain flow point is: There can be multiple sets of water flow standard devices. When two sets of water flow standard devices are used in the test, let the average instrument coefficient of the turbine flow sensor at a certain flow point based on the first set of water flow standard devices be . The turbine flow sensor at this flow point has an average instrument coefficient based on the second set of water flow standards. The average meter coefficient for this flow point is:

[0086]

[0087] In the formula, This represents the average instrument coefficient of the turbine flow sensor at a given flow rate point.

[0088] Furthermore, the comparison control value is calculated from three data points: the average instrument coefficient of the turbine flow sensor at a certain flow point, the average instrument coefficient of the turbine flow sensor under each set of water flow standard devices at that flow point, and the different expanded uncertainties of the different water flow standard devices. When two sets of water flow standard devices are used in the test, combined with Equation 3, the comparison control value at that flow point is:

[0089]

[0090] In the formula, E n For comparison of control values, dimensionless; U1 is the expanded uncertainty of the first set of water flow standard devices; U2 is the expanded uncertainty of the second set of water flow standard devices.

[0091] In this embodiment, by calculating the average instrument coefficient data, the average instrument coefficient, measurement repeatability, and comparison control values ​​at each measurement point that characterize the performance of the turbine flow sensor are calculated to ensure the accuracy of the test analysis.

[0092] In one embodiment, such as Figure 4 As shown, the performance of the turbine flow sensor is analyzed based on the average instrument coefficient, measurement repeatability, and comparative control values ​​at each measurement point, including:

[0093] Step 402: Take the maximum and minimum values ​​from the average instrument coefficients of the corresponding flow points, compare the difference between the maximum and minimum values ​​with the set stability deviation value, and determine whether the stability of the turbine flow sensor is qualified based on the comparison result.

[0094] Specifically, Equation 3 can be used to obtain the average instrument coefficient of the turbine flow sensor at a certain flow point. Since there are multiple flow points, the maximum and minimum values ​​are selected from the average instrument coefficients at each flow point, and the difference between the maximum and minimum values ​​is calculated. This difference is compared with a set stability deviation value. If the difference is less than or equal to the set stability deviation value, the stability of the turbine flow sensor can be judged to be qualified. Operators can also list the average instrument coefficients of each flow point sequentially and compare them with the overall linear fitting error line to obtain test results on whether the overall change is stable and whether the error at a single point is too large.

[0095] Furthermore, the set stability deviation value is not unique, and is usually selected as 1%. The linear fitting error line is usually obtained by linearly fitting the average instrument coefficient of each flow point using the least squares method.

[0096] For example, such as Figure 5 As shown, there are four flow points. The line connecting the average instrument coefficients of each flow point is a solid line, and the linear fitting error line is a dashed line. The maximum average instrument coefficient for each flow point is 7.88, and the minimum average instrument coefficient is 7.84. The difference between the maximum and minimum values ​​is 0.04, which is less than the set stability deviation value of 1%. Therefore, the stability of the turbine flow sensor tested is qualified. Operators can observe that the average instrument coefficients of each flow point have the same trend of change at the corresponding flow points, and the change is stable compared with the linear fitting error line, with small errors at each point.

[0097] Step 404: Compare the measured repeatability with the set repeatability threshold, and determine whether the repeatability of the turbine flow sensor is qualified based on the comparison result.

[0098] Specifically, Equation 2 can be used to obtain the measurement repeatability of the turbine flow sensor at a certain flow point based on the instrument coefficient of a water flow standard device of a certain diameter. The measurement repeatability is compared with the set repeatability threshold. If the measurement repeatability is less than or equal to the set repeatability threshold, the repeatability of the turbine flow sensor can be judged to be qualified.

[0099] Optionally, the set repeatability threshold is not unique and can be set to 0.05. That is, when the measured repeatability value is less than or equal to 0.05, the repeatability of the turbine flow sensor is considered to be qualified.

[0100] Step 406: Compare the comparison control values ​​at each measurement point with the set comparison control value threshold, and determine whether the consistency of the value transmission of the turbine flow sensor is qualified based on the comparison results.

[0101] Specifically, the comparison control value can be obtained from Equation 4. The comparison control value is compared with the set comparison control value threshold. If the comparison control value is less than or equal to the set comparison control value threshold, it can be determined that the value transmission consistency of the turbine flow sensor is qualified and maintains a high value transmission consistency.

[0102] Optionally, the comparison control value threshold is usually set to 1. When the comparison control value is less than or equal to 1, it means that the comparison result meets the requirements.

[0103] In this embodiment, by analyzing the average instrument coefficient, measurement repeatability, and comparison control values ​​at each flow point, accurate multi-dimensional testing and analysis of the turbine flow sensor can be achieved.

[0104] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0105] Based on the same inventive concept, this application also provides a turbine flow sensor testing and analysis device for implementing the turbine flow sensor testing and analysis method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations of one or more turbine flow sensor testing and analysis device embodiments provided below can be found in the limitations of the turbine flow sensor testing and analysis method described above, and will not be repeated here.

[0106] In one embodiment, such as Figure 6As shown, a turbine flow sensor testing and analysis device is provided, comprising: an instrument coefficient acquisition module 602, an instrument coefficient processing module 604, a first data processing module 606, a second data processing module 608, and a data analysis module 609, wherein:

[0107] The instrument coefficient acquisition module 602 is used to acquire the instrument coefficients obtained by the turbine flow sensor from the flow point measured on the water flow standard device of different diameters. The turbine flow sensor is installed on the water standard flow device, which is used to calibrate the standard flow.

[0108] The instrument coefficient processing module 604 is used to calculate the average instrument coefficient of the turbine flow sensor under the corresponding diameter water flow standard device based on the instrument coefficients measured by the turbine flow sensor on water flow standard devices of different diameters at the same flow point.

[0109] The first data processing module 606 calculates the measurement repeatability and the average instrument coefficient of the corresponding flow point based on the average instrument coefficient of the turbine flow sensor under the water flow standard device of the corresponding diameter.

[0110] The second data processing module 608 is used to calculate the comparison control value at each measurement point based on the average instrument coefficient of the turbine flow sensor at different flow points.

[0111] The data analysis module 609 is used to analyze the performance of the turbine flow sensor based on the average instrument coefficient, measurement repeatability, and comparative control values ​​at each measurement point.

[0112] In one embodiment, the first data processing module 606 is used to calculate the measurement repeatability of the turbine flow sensor based on the average instrument coefficient of the turbine flow sensor under the corresponding diameter water flow standard device and the measured instrument coefficient; and to average the average instrument coefficient of the turbine flow sensor under different diameter water flow standard devices to obtain the average instrument coefficient of the corresponding flow point.

[0113] In one embodiment, the data analysis module 609 is used to take the maximum and minimum values ​​of the average instrument coefficients at the corresponding flow points, compare the difference between the maximum and minimum values ​​with a set stability deviation value, and determine whether the stability of the turbine flow sensor is qualified based on the comparison result; compare the measurement repeatability with a set repeatability threshold, and determine whether the repeatability of the turbine flow sensor is qualified based on the comparison result; and compare the comparison control values ​​at each measurement point with a set comparison control value threshold, and determine whether the consistency of the value transmission of the turbine flow sensor is qualified based on the comparison result.

[0114] Each module in the aforementioned turbine flow sensor testing and analysis device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in the processor of a computer device in hardware form or independent of it, or stored in the memory of a computer device in software form, so that the processor can call and execute the corresponding operations of each module.

[0115] In one embodiment, an intelligent flow measurement device is provided, including a turbine flow sensor 102 and an intelligent control unit 104. The intelligent control unit 104 is connected to the turbine flow sensor 102 and is used to test and analyze the turbine flow sensor 102 according to the method described above.

[0116] Specifically, the intelligent control unit 104 is connected to the turbine flow sensor 102 to acquire the measurement data of the turbine flow sensor 102. The measurement data includes flow information and meter coefficient.

[0117] In one embodiment, the intelligent flow measurement device further includes at least one of a current sensor, a power sensor, a voltage sensor, a temperature sensor, and a humidity sensor connected to the intelligent control unit 104.

[0118] Specifically, the turbine flow sensor 102 and the intelligent control unit 104 can be detachably connected. The turbine flow sensor 102 can be replaced with at least one of a current sensor, a power sensor, a voltage sensor, a temperature sensor, and a humidity sensor. The intelligent control unit 104 can receive and analyze various measurement data to measure various parameters.

[0119] Furthermore, replacing the turbine flow sensor 102 with at least one of a current sensor, a power sensor, a voltage sensor, a temperature sensor, and a humidity sensor means that it can be replaced with one of the current sensor, power sensor, voltage sensor, temperature sensor, and humidity sensor, or it can be replaced with a composite sensor that includes, but is not limited to, detecting at least one of the data of flow rate, current, power, voltage, temperature, and humidity.
