Wafer Type Vortex Flow Meter

  1. Mainly used for steam, gas, water
  2. With 4-20mA, RS485, HART output
  3. Easy to install and maintain,shock resistant
  4. Various structural forms, flange type, wafer type,insertion type.

Vortex flow meter is one kind of velocity type flow meter, it’s based on Karman vortex theory and adopts piezoelectric crystal to detect the burble frequency of the fluid caused by flowing through the triangular prism in the pipeline and then measure the flow of fluid. It is widely used in petrol, chemical industry, light industry and power heat supply and so on.

Integrated pressure and temperature compensation.
4-20mA, pulse with HART; Optional pulse with RS485
Wide temperature range up to highest temperature 350
Adopt Japan OVAL technology and design
Embedded sensor, 4 piezo-electric crystal encapsulated inside the sensor.
No moving parts, no abrasion, non-wearing parts inside, fully welded SS304 body (Optional SS316)
