The steam vortex flowmeter is mainly used for the flow measurement of the steam medium fluid in the industrial pipeline. The steam vortex flowmeter is characterized by small pressure loss, a large range, and high accuracy. It is almost independent of the fluid density and pressure when measuring the volume flow of the working condition. , Temperature, viscosity and other parameters. There are no movable mechanical parts, so the reliability is high and the maintenance is small. The instrument parameters can be stable for a long time. The steam vortex flowmeter adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20℃～+250℃. There are analog standard signals and digital pulse signal outputs, which are easy to use with digital systems such as computers. It is a relatively advanced and ideal flow meter
