Due to their inherent characteristics, flow meters require calibration after prolonged use; otherwise, their measurement accuracy will decrease, potentially damaging product quality. Therefore, flow meters are typically calibrated periodically during use.

[0042] Flow meters can measure the flow rate of liquids or gases in pipelines. After prolonged use, they need to be calibrated; otherwise, the decreased measurement accuracy of the flow meter may lead to damage to product quality.

[0043] In related technologies, flow meter calibration requires first removing the flow meter from the production system and then installing it into a calibration device for calibration. Since the flow meter is installed on the flow pipeline and is not easy to remove, and removing the flow meter will cause production interruption, the calibration efficiency and accuracy of the flow meter are low.

[0044] To address the technical problems existing in related technologies, embodiments of this application provide a flow meter calibration device. See also... Figure 1 As shown, some embodiments of the flow meter calibration apparatus of this application include:

[0045] Flow line 10;

[0046] A standard flow meter 21 is installed in the flow pipeline 10 and is used to detect the flow rate of the medium in the flow pipeline 10.

[0047] Temperature control module 22 is located near flow pipeline 10 and is used to control the temperature of the medium in flow pipeline 10;

[0048] Temperature sensor 23 is installed in flow line 10 to detect the temperature of the medium inside flow line 10;

[0049] Pressure sensor 24 is installed in flow line 10 and is used to detect the pressure of the medium in flow line 10.

[0050] In the above embodiments, the connection between the flow line 10 and the pipeline where the flow meter under test is located can be a direct connection, such as a plug-in connection or a threaded connection. Alternatively, the flow line 10 and the pipeline where the flow meter under test is located can be connected via a connector, such as a pipe with joints at both ends, with each end connected to the flow line 10 and the pipeline where the flow meter under test is located, respectively. The specific structural form of the connection between the flow line 10 and the pipeline where the flow meter under test is located is not limited in this application embodiment.

[0051] In the above embodiments, the temperature control module 22 is located near the flow pipeline 10 and is used to control the temperature of the medium inside the flow pipeline 10. For example, the temperature control module 22 includes a resistance wire, a variable resistor, and a power supply. The resistance wire is wound around the flow pipeline 10, and the variable resistor is connected in series with the resistance wire to form an adjustable resistance value. The positive and negative terminals of the power supply are connected to the adjustable resistance value to form a closed circuit. By adjusting the resistance value of the variable resistor, the temperature of the medium inside the flow pipeline 10 can be controlled. In other embodiments, infrared heating, jacketed water heating, or other methods can also be used to control the temperature of the medium inside the flow pipeline 10.

[0052] In this embodiment, the flow pipeline 10 can be connected to the pipeline where the flow meter under test is located. In use, one end of the flow pipeline 10 is connected to the pipeline where the flow meter under test is located, allowing the medium in the pipeline where the flow meter under test is located to pass through the flow pipeline 10. A standard flow meter 21 is installed in the flow pipeline 10 to detect the flow rate of the medium. This setup allows for online flow rate detection of the medium using the standard flow meter 21 without disassembling the flow meter under test, thereby calibrating the flow meter under test and improving calibration efficiency. The temperature control module 22 can regulate the temperature of the medium, making its temperature close to the temperature of the medium in the pipeline where the flow meter under test is located, thereby reducing the impact of temperature changes during transmission on calibration accuracy and improving calibration accuracy. The temperature sensor 23 and pressure sensor 24 can measure the temperature and pressure of the medium passing through the flow pipeline 10 to obtain temperature and pressure parameters. These temperature and pressure parameters can be used to correct the data detected by the standard flow meter 21, further improving calibration accuracy.

[0053] In some embodiments, the flow meter calibration device further includes a flow regulating component 25, which is disposed in the flow pipeline 10 for regulating the flow rate of the medium in the flow pipeline 10.

[0054] The flow regulating component 25 can be an electrically operated regulating valve that automatically regulates the flow rate, or a manually operated regulating valve that manually regulates the flow rate. Under different flow conditions, the error values ​​between the flow meter under test and the standard flow meter are not exactly the same. In order to improve the calibration accuracy of the flow meter under test, the flow regulating component 25 is used to adjust the flow rate of the medium in the flow pipeline 10. This allows for the calibration of the flow meter under test under different flow conditions, thereby improving the calibration accuracy of the flow meter under test.

[0055] In some implementations, a shut-off valve 60 is also provided on the flow line 10.

[0056] In the above embodiment, by using the shut-off valve 60 to adjust the medium pressure in the flow pipeline 10, the flow error between the flow meter under test and the standard flow meter under different medium pressures can be detected and calibrated, further improving the calibration accuracy of the device.

[0057] In some embodiments, the flow meter calibration device further includes an electronic soap film flow meter 30, which is disposed in the flow pipeline 10 for detecting the flow rate of the medium in the flow pipeline 10.

[0058] In the above embodiments, the electronic soap film flow meter 30 can detect the flow rate of the medium in the flow pipeline 10, and then verify the flow detection data of the standard flow meter 21, thereby further improving the accuracy of the measurement results.

[0059] In some embodiments, the flow meter calibration device further includes:

[0060] The control component (not shown in the figure) is communicatively connected to the standard flow meter 21, the temperature control module 22, the temperature sensor 23, and the pressure sensor 24.

[0061] The data acquisition component 40 is connected in communication with the control component and is used to acquire the flow data of the flow meter under test.

[0062] In the above embodiments, the control component can be a PLC control system, and the data acquisition component 40 can be an infrared switch.

[0063] In the above embodiments, firstly, the control component issues a data acquisition control command. The standard flow meter 21, temperature sensor 23, and pressure sensor 24 acquire corresponding data information according to the data acquisition control command and transmit it to the control component. Simultaneously, the data acquisition component 40 acquires the flow data of the flow meter under test according to the data acquisition control command and transmits it to the control component. The control component processes the received flow data, temperature data, and pressure data, and then outputs the flow error between the flow meter under test and the standard flow meter 21 under the same conditions. Then, the flow meter under test is calibrated based on the output flow error. When it is necessary to detect the flow error between the flow meter under test and the standard flow meter 21 at different temperatures, the control component issues a temperature adjustment control command to the temperature control module 22. The temperature control module 22 controls the temperature of the medium in the flow pipeline 10 according to the temperature adjustment control command, and then the same steps described above can be used to detect and calibrate the flow of the flow meter under test and the standard flow meter 21.

[0064] It should be noted that the flow data of the standard flow meter 21 is automatically displayed by the standard flow meter 21 and then transmitted to the control component. The flow data of the flow meter under test is read by the data acquisition component 40 (i.e., infrared switch) and then transmitted to the control component. The control component can then process the data based on the flow data, temperature data and pressure data of the flow meter under test and the standard flow meter 21, and finally calculate the flow error between the flow meter under test and the standard flow meter 21.

[0065] See Figure 2 As shown, in some embodiments, an electrical control box 50 is also included, in which calibration components, control components and data acquisition components 40 are integrated.

[0066] In the above embodiments, the calibration component, control component and data acquisition component 40 are integrated into the electrical control box 50, which is convenient for operators to carry and facilitates on-site online testing and calibration.

[0067] In some embodiments, a data interaction component 51 is also included, which is disposed on the electrical control box 50 and is communicatively connected to the control component.

[0068] In the above embodiments, the data interaction component 51 is a smart touch screen. The smart touch screen can display the data of the standard flow meter 21, temperature sensor 23, pressure sensor 24 and the flow meter under test in real time. At the same time, the staff can input control parameters and control commands based on the smart touch screen. The control component controls the operation of each component and the data transmission based on the input control parameters and control commands, thereby realizing automated calibration control.

[0069] In some embodiments, a data printing component 52 disposed on the electrical control box 50 is also included, which is connected to the control component for real-time printing of calibration data.

[0070] In the above embodiments, when calibration data needs to be printed, the staff inputs a printing command to the control component through the data interaction component 51. The control component can then control the data printing component 52 to print the calibration data of the calibration component based on the input printing command.

[0071] In the above embodiments, the data printing component 52 is a small barcode printer.

[0072] In some embodiments, a battery assembly 53 disposed within the electrical control box 50 is also included.

[0073] In the above embodiment, the battery assembly 53 is a rechargeable lithium battery. The battery assembly 53 can provide power to the electrical components inside the electrical control box 50, ensuring the normal calibration operation of the calibration device.

[0074] In some implementations, a wireless communication module (not shown) located within the control component is also included for data exchange with an external cloud.

[0075] It should be noted that, in the above embodiments, the wireless communication module installed in the control component should be compatible with the wireless communication module in the external cloud device. The wireless communication methods include, but are not limited to, Bluetooth, and WIFI. The wireless communication module enables data exchange between the control component and the external cloud device, facilitating the backup of the device's calibration data to prevent data loss.

[0076] In some embodiments, the electrical control box 50 is provided with a handle 54.

[0077] In the above embodiments, by providing a handle 54 on the electrical control box 50, it is convenient for operators to carry the electrical control box 50.
