[0002] Flow transmitter, also known as flow sensor or simply flow meter, is a new generation of high-precision and high-reliability precision metering instrument developed by combining advanced flow meter technologies at home and abroad, integrating temperature, pressure, flow sensor and intelligent flow integrator. Flow transmitter is widely used in urban pipeline gas metering, industrial gas metering, gas pressure regulating station metering, energy management and other non-corrosive gas metering or flow control occasions.
[0003] Since the sealing must be ensured when the flow transmitter is connected to the pipeline, most of the existing flow transmitters are connected through flanges. The flanges need to be kept clean during connection, and an isolation pad needs to be added between the two flanges to ensure the sealing. Since the surface of the flanges is smooth, there is a problem of misalignment of the fixing holes between the flanges on the existing flow transmitter and the flanges on the pipeline, which affects assembly. The inconvenience during longitudinal assembly affects work efficiency.
[0004] For this reason, we propose a flow transmitter with a limiting effect. Utility Model Content
