Product Description
Volumetric vortex flow meter
DH800 volumetric 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
