SV21 Vortex Flowmeter (Wafer) ,Water Vortex Flowmeter,water type vortex flowmeter for gas

Vortex flow meter can measure the mass flow rate of any gas or liquid and are ideally suited for saturated or superheated steam.

Technical Features:

No moving parts, high reliability and durability

Convenient installation and maintenance

Sensor not contact the measured fluids directly, stable performance and long service life

Output pulse signal is directly proportional to flow rate, high accuracy and no zero drift

Wide measuring range, turndown ratio 10:1

Low pressure loss, low cost

Frequency output not affected by the fluid change in physical character and composition, meter factor (K) only considers shape and dimension of eddies. Measurement of volumetric flow can get compensation once it needs. Then no re-calibration meter factor needed if damaged parts be exchanged

Wide application for steam, gas, liquid
