Vortex Flow Meter RVL Series DESCRIPTION The RVL liquid flow meter uses vortex-shedding technology with embedded piezoelectric pressure sensors. The meter has no moving parts, and any potential for fluid contamination is eliminated by the non-metallic corrosion-resistant body materials. The meter includes a compact plug-in transmitter module with two-wire 4…20 mA or three-wire pulse output. All electronics are housed in a corrosionresistant enclosure. Units can be recalibrated and reprogrammed in the field. APPLICATION The RVL is perfect for aggressive or easily contaminated fluids. • Ultra-pure water distribution RO/DI skids Cooling water Chemical injection Nonabrasive slurries OPTIONAL SOFTWARE OPERATING PRINCIPLE Operation of the RVL vortex flow meter is based on the vortex shedding principle. As fluid moves around a strut, vortices (eddies) are formed and move downstream. They form alternately, from one side to the other, causing pressure fluctuations that are sensed by a piezoelectric crystal in the sensor tube. The frequency of the vortices is directly proportional to the flow rate. Transmitting Transducer Small Strut An optional software utility kit is available to configure the RVL 4…20 mA output. (The pulse output is not field configurable.) Part number RVS220-954 contains a RS232 nine-pin cable, software CD, TTL to RS232 converter and a board interface cable. The program enables easy configuration of span, damping and units of measurement. Shed Vortices Receiving Transducer CONSTRUCTION The precision machined bodies provide quality end fittings, while avoiding ionic contamination. There are no metallic wetted parts, gaskets or elastomers in the meter. The body material selected is homogeneous throughout the flow path.

Material Selection MATERIAL SELECTION When choosing the best flow meter for a process, review the concentration, operating temperatures and operating pressure of the fluid being measured. In a thermoplastic piping system, choose the same material for the meter and the pipe wherever possible to maintain fluid compatibility and aid in bonding the materials. The table below shows the compatibility of fluid types with thermoplastic materials.
