KVF series vortex flow sensor

Product Details

KVF series vortex flow sensor

Industrial pipeline medium fluid: can be widely used for measuring superheated steam, saturated steam, compressed air, and general gases.

The piezoelectric crystal is built into the vortex generator, with no zero drift and stable long-term measurement.
Flow sensors have good interchangeability, strong component universality, and reduce operation and maintenance costs.
When measuring liquid volume flow rate, temperature and pressure compensation are not required, and the output signal is linearly related to the flow rate.
The pressure loss is small, only 1/4~1/2 of the plate hole.
The structure is simple and sturdy, with no movable parts, high reliability, and easy to use and maintain.
The detection component does not come into contact with the medium, with stable performance and long service life.
Intrinsic safety and explosion-proof types are optional.

Measuring fluids: saturated steam, superheated steam, gas, liquid (avoid multiphase flow)
