Vortex Flow Meter
Product Description
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, combied with isolation, sheilding, filtering and other measures, overcome the problems of poor shock resistance and small signal data disorder of similar products, and adopts and sensor packaging technology and protective measures to ensure the reliability of the product.
Product Features
- Small pressure loss, alrge measuring range tnd high precision.
- Not affected by fluid density, pressure, temperature, viscosity, etc.
- No moving mechnical parts, high reliability and low maintenance.
- Instrument parameters can be stable for a long time.
- 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.
