Series RVL Vortex Flowmeter
1/4” to 3” Pipe Size, PVC, CPVC, or PVDF Construction
DESCRIPTION
The operation of the RVL vortex flow meter is based on the vortex shedding principle. As fluid moves around a body, vortices (eddies) are formed and move downstream. They form alternately, from one side to the other, causing pressure fluctuations. These are sensed by a piezoelectric crystal in the sensor tube, and are converted to a 4-20 mA, 0-5 VDC or pulse signal.
The frequency of the vortices is directly proportional to the flow. This results in extremely accurate and repeatable measurements with no troublesome moving parts.
Unlike stainless steel or paddle wheel designs, the vortex sensor is perfect for aggressive or easily contaminated flow media.
Applications include flow monitoring and control of corrosive chemicals and slurries in chemical processing, water/wastewater, and DI water.
