What makes VFM60MV ideal for steam measurement?
Direct Mass Flow Measurement for Saturated Steam/Superheated Steam
Vortex flow meters are widely used for steam flow measurement due to their robustness, low maintenance, and ability to handle high temperature and pressure. The VFM60MV vortex flow meter goes one step further with smart electronics and integrated compensation features.
Typical benefits of vortex steam flow meters:
-
No moving parts → low maintenance
-
Suitable for high-temp, high-pressure steam
-
High reliability and long service life

Comate understood Vibration then build a new equipment to measure it. Early in 2015, Comate have cooperated with USTC signal processing laboratory and put an unique design method in order to detect the real change of electric charge completely generated by fluids. After that Comate put VFM60MV in factory like compressed air, boiler steam, heating system nad owned a good feedback. The interference solved also makes Comate vortex meter able to measure down to 2m/s velocity than other brand in the marketplace.
