Vortex Gas Flowmeter

The VI 800 Vortex Gas Flowmeter is offered in co-operation with J-Tec Associates, U.S.A. A Vortex technology is employed by optimising a strut to produce vortices at lower flow, which are detected ultrasonically, detectors then detect.


The flowmeter is ideally suited to applications where gas flow is low and contains higher levels of moisture or particulates. Typical applications include Stack and Flare gases, Bio-gas and other Off-gases from sewage digesters and landfills.
