[0002] Measurement is the eye of industrial production. Flow measurement is one of the components of measurement science and technology. It is closely related to the national economy, national defense construction, and scientific research. Doing this work well is important for ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially in today's era of energy crisis and increasing automation of industrial production, the status and role of flow meters in the national economy are more obvious.

[0003] The prior art provides an automatic calibration device for a flow meter (Announcement No. CN218847357U). The utility model includes a support platform and a water pump. A fixed seat is equidistantly fixedly connected to the top of the support platform. A quantitative controller is fixedly installed on one side of the top of the fixed seat. Two water pumps are provided. The water pumps are fixedly installed on both sides of the top of the support platform respectively. The output end of the water pump...by adjusting the water pump or controlling the closing size of the solenoid valve, the flow rate is adjusted to achieve the effect of quantitative control. The flow rate can also be easily identified according to the height of the slide rod when the liquid flows, making observation and detection more convenient and quick.

[0004] The above-mentioned automatic flow meter calibration device can only provide quantitative control function and simple flow identification function in actual use. However, it lacks automatic flow control adjustment when the pressure in the pipeline is too high. When the problem is found, the pipeline often has a large abnormality. Therefore, we need to propose a flow meter automatic calibration device. Utility Model Content

When the pressure in the pipeline is detected to be too high, the pressure sensor can feed back a signal to a controller. After the controller receives the feedback signal from the pressure sensor, the closing size of the first solenoid valve is controlled to adjust the pressure in the pipeline, thereby achieving the purpose of pressure control and preventing the pressure in the pipeline from being too high, which may cause pipeline abnormalities. In addition, the pressure data is transmitted to a host computer through the cooperation of a network transmission module and a network receiving module, so that workers can remotely monitor the pressure through the host computer and can discover and handle the problems in time.
