Universal FlowMonitors” P420 Series vortex-shedding flowmeters are designed to meetthe requirements of water desalination, chemical, and water treatmentoperations. The meters feature an inexpensive flowrate transmitter with no movingparts that can stick, bind, or coat when processing corrosivefluids. Applications include water, chemicals, brine, corrosivesand low-viscosity pure liquids. The flow transmitters are electronic instruments with wetted partsentirely of polyvinyl chloride (PVC). The metersare designed to transmit low-viscosity liquids that are compatible withPVC, including water that may contain particles. Available in five pipe sizes with maximum flow rates from12 gallons per minute (45 liters per minute) to 200 GPM (750LPM).  Pipe sizes and maximum flow rates are: 1/2 inch ( 12GPM, 45 LPM), 3/4 inch (25 GPM, 95 LPM), 1 inch (50 GPM, 190 LPM),1-1/2 inches (100 GPM, 380 LPM) and 2 inches (200 GPM, 750 LPM). No o-ring seals — connection is made by either solvent welding PVC pipe into the socketport provided or threaded connection. Electronic output is from a 4-20 mA, two-wire transmitter ratedIntrinsically Safe when used with barriers. The electronicspackage is totally potted and not vulnerable to shorting, corrosion,leaks, humidity, or condensate from conduits or thermalcycling.
