Description

Technical Field

[0001] The utility model relates to the field of pneumatic liquid level gauges, and specifically to a gas circuit structure of a pneumatic liquid level gauge. Background Technique

[0002] The pneumatic liquid level gauge mainly consists of a blowing device, a differential pressure (pressure) transmitter, and a blowing gas circuit. The blowing gas circuit is used for the flow of air.

[0003] The existing pneumatic liquid level gauges require two differential pressure transmitters. When connecting, three pipes are branched out. Three flow stabilizer valves are needed to control the flow rate, three flow meters are needed to display the flow rate, and one common terminal is needed. Therefore, the two transmitters need to be connected. There are two connection methods. One is to connect the hard pipes with ferrule joints, and other components and the inlet and outlet are all connected by ferrule joints. Therefore, more ferrules are used in the gas circuit structure.

[0004] However, the gas circuit structure of the existing pneumatic liquid level gauges is composed of a relatively large number of ferrule structures to form the pipeline. Its structural feature is that there are many leakage points, and leakage is extremely likely to occur. And because hard pipes are used, maintenance is extremely troublesome, and a large amount of manpower and time are required for assembly and calibration, and the service life is relatively short. Therefore, a gas circuit structure of a pneumatic liquid level gauge is proposed. Content of the Utility Model
