Liquid Flow Meter eliminates media compatibility issues.July 27, 2007 -
Constructed with thermoplastic body and no gaskets or elastomers, solid-state RVL series measures flow rates electronically using vortex shedding technology. It provides repeatable ±1% FS accurate measurement without fluid contamination. Suited for aggressive or easily contaminated flow media, series is offered in PVDF, Polypropylene, PVC, and CPVC. All units come precalibrated for specific use, but can be recalibrated in field via PC-based software program.

New Vortex Meter has Advantage - Its Body Material
New to the Racine vortex line is the RVL series liquid flow meter. One advantage to utilizing an RVL, is there are no gaskets or elastomers in the meter so the only compatibility concern is the thermoplastic material used for the body construction. The RVL has no moving parts, and the meter provides a repeatable ±1% full-scale accurate measurement without fluid contamination.
The RVL series flow meter is available in PVDF, Polypropylene, PVC and CPVC, to suit a variety of fluids and process systems. Unlike stainless steel or paddle wheel designs, the RVL is perfect for aggressive or easily contaminated flow media. Suitable applications run from corrosive chemicals to ultra-pure water. For semiconductor and other sensitive environments, RVL meters are cleaned and bagged to Class1000 clean room standards.
Flow rates are measured electronically, using accurate vortex shedding technology. As fluid moves across a bluff body or "strut", vortices are formed downstream. These shed vortices cause pressure fluctuations which are detected by a highly-sensitive piezoelectric crystal in the meter body, and are converted to an analog output signal. The vortex-shedding frequency is directly proportional to fluid velocity.
The RVL is precalibrated for specific use, but may be recalibrated in the field with the use of a PC-based software program, with no reduction in accuracy.
