These economical vortex flowmeters are suitable for water and water glycol-based heat exchange systems. The transmitters work on the vortex shedding flow principle. As flow velocity increases, alternating vortices are formed on each side of the bluff body within the flowtube and travel downstream. The flowmeters utilize piezoelectric sensors embedded in a vane downstream from the bluff to detect the vortices and transfer the sensed vortices into flow velocity. A flow factor is provided to convert frequency to volumetric flow rate for each size of flowmeter. Flowmeters have a PT1000 RTD for temperature measurement of the media
Note: Media with viscosity greater than 2 centipose will require higher flow rates to form measurable vortices within the flowtube.
