Universal Flow Monitors has introduced vortex-shedding flow-rate transmitters made of chlorinated polyvinyl chloride (CPVC) for heat resistance.

These transmitters are suitable for processing corrosive fluids, water, brine and low-viscosity fluids in water treatment, chemical and desalination applications.

The P420 plastic flowmeters include models with wetted parts made of either CPVC or PVC (polyvinyl chloride).

The flow rate transmitters don’t have moving parts that can stick, bind or coat when processing water or corrosives.

P420 vortex shedding meters with CPVC body, sensor and bluff can transmit hot water or other fluid with maximum operating temperatures of 82C.

CPVC transmitters can accommodate higher maximum operating pressures than PVC units at temperatures of 27 to 82C.

Universal Flow Monitors offers CPVC and PVC units in five-pipe diameters, providing a flow range from 12 to 200 gallons a minute (4.5 to 750 litres a minute).

The pipe-sizes with full-scale flow rates are: 1/2in (1.27cm) (1.2 to 12 GPM, 4.5 to 45 LPM), 3/4in (2.5 to 25 GPM, 9.5 to 95 LPM), 1in (5 to 50 GPM, 19 to 190 LPM), 1-1/2 in (10 to 100 GPM, 38 to 380 LPM) and 2in (20 to 200 GPM, 75 to 750 LPM).

The meters with CPVC wetted parts can transmit low-viscosity, PVC-compatible fluids that may contain particles.

P420 Series CPVC and PVC transmitters are electronic instruments that, unlike mechanical switches, eliminate the potential for clogging.

P420 vortex shedding flow transmitters have no o-ring seals.

Connection is made by either solvent-welding the PVC or CPVC pipe into the socket port provided or by NPT threaded connection.

Electronic output is from a 4-20 mA two-wire transmitter rated intrinsically safe when used with barriers.

The electronics package is totally potted and not vulnerable to shorting, corrosion, leaks, humidity or condensate from conduits or thermal cycling.
