Intelligent vortex flowmeter is mainly used for flow measurement of industrial pipeline medium fluids, such as gas, liquid, steam 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, low maintenance, and long-term stability of instrument parameters. This flowmeter integrates flow rate, temperature, and pressure detection functions, and can perform temperature, pressure, and automatic compensation. It is an ideal instrument for gas measurement in industries such as petroleum, chemical, power, and metallurgy. Using piezoelectric stress sensors, it has high reliability and can operate within a temperature range of -20 ℃ to+250 ℃. It has analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.
