Methodology adopted by PROMECON’s MECONTROL Air

System utilizes the triboelectric principleMetal sensors placed parallel to flowElectrical signals created by dust particlesParticle movement correlated & referencedTime shift & distance provide flow velocity

Aspects of measuring dusty gas streams

Location of the duct (accessibility & safety)Temperature, Pressure and MoistureFluctuation in flow rateDust concentration of the stream
