Intelligent vortex flowmeter is mainly used for flow measurement of industrial pipeline medium fluids, such as gas, liquid, vapor 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 instrumentationparameterCan maintain long-term stability. The intelligent vortex flowmeter adopts a piezoelectric stress sensor, which has high reliability and can be used in-20℃～+250℃Working within the working temperature range. It 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 a relatively advanced and ideal flow measurement instrument.

For ease of use,BatteryThe locally displayed vortex flowmeter with power supply adopts micro power consumption high-tech and adoptslithium batteryThe power supply can operate continuously for more than a year, saving the procurement and installation costs of cables and display instruments. It can display instantaneous flow, cumulative flow, etc. on site. The integrated vortex flowmeter with temperature compensation also comes with a temperature sensor, which can directly measure the temperature of saturated steam and calculate the pressure, thereby displaying the mass flow rate of saturated steam. Temperature and pressure compensation integrated with temperaturePressure sensorUsed for gas flow measurement, it can directly measure the temperature and pressure of the gas medium, thereby displaying the standard volumetric flow rate of the gas.
