GVF200 digital liquid vortex flow meter is a flow meter operating with Karman Vortex Street principle for flow rate of liquids (water, high temperature water, oil, beverage, chemical liquids, etc.). It could be used in automatic control system as flow transmitter. The product adopted advanced differential technique, together with measurement of isolating, shielding and filtering, it had possesses better anti-vibration performance and signal stability. GVF200 liquid flow meter is also with unique sensor encapsulation and protection technology to ensure service life of the sensor.
1.Good anti-vibration performance.
2.Low pressure loss and consumption
3.easy to install and maintain the product
