1Introduction to Split type Steam Flow Meter:
Jiangsu Changshun InstrumentSplit type steam flowmeterIt has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is an ideal high-precision flow meter. Mainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, vapors, and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can remain stable for a long time. The vortex flowmeter adopts a piezoelectric stress sensor with high reliability and can operate within a temperature range of -20 ℃ to+250 ℃.
