Vortex flow meter is developed according to the principle of Karman vortex, and is used to measure the volume flow of gas, steam or liquid, and the volume flow or mass flow of standard conditions. The differential pressure technology used, combined with isolation, shielding, filtering and other measures, overcomes the problems of poor shock resistance and small signal data disorder of similar products, and adopts the sensor packaging technology and protective measures to ensure the reliability of the product.
Features:
* A wide range of measuring media, liquids, gases and steam can be measured;
* With temperature and pressure compensation function, stable measurement.
* It can transmit flowsignals over long distances, and can be networked with computers to achieve centralized management;
* The sensor is made of stainless steel, which is corrosion resistant.
* Small pressure loss, large measuring range and high precision
* Not affected by fluid density, pressure, temperature, viscosity, etc.
* No moving mechanical parts, high reliability and low maintenance.
* Adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20℃～+250℃.
* Analog standard signals and digital pulse signal outputs, which are easy to use with digital systems such as computers.
