Vortex Flowmeters

EMIS-VIHR 200 Vortex flow meters

Designed to measure the volume and volume flow of liquids, gases (natural gas, associated petroleum gas, hydrogen, oxygen, air and other gases), saturated and superheated steam, corrosive media at operating pressure and operating temperature as well as the volume and volume flow rate of gas reduced converted to standard conditions in various industries.

They are used both for direct flow measurement of most process media and as part of commercial energy metering units including in heat supply systems, CWS, HWS.

If the working fluid density is constant, it is possible to measure mass and mass flow rate by setting the density in the calculator of the electronic unit of the flow meter.

Specific features and advantages

• One of the best measurement accuracy for vortex flow meters in Russia: ±0.5% for liquid media and ±0.7% for gas environment.
• High metrological stability of measurements.
• Measurement of mass flow rate of liquids, saturated and superheated steam as well as volumetric flow rate of gas media under standard conditions with standardized error in accordance with GOST, GSSSD (for electronic unit version with «VV» calculator).
