Insert Vortex Flowmeter-China flow meter. Level meter manufacturer-Kaifeng Huabang Instrument Co.,LTD

Product description

The plug-in plug-in vortex flowmeter is mainly used for the flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range, and high accuracy. It is hardly affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. 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. This instrument adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -25℃~+320℃. It has analog standard signal and digital pulse signal output. It is easy to use with digital systems such as computers. It is a relatively advanced and ideal flow meter.
