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
