The new P420 Series of vortex-shedding flowmeters meets requirements for an inexpensive flow rate transmitter without moving parts that can stick, bind or coat when processing cooling or quenching water and corrosive fluids. Applications include flows to transformers, cables and coils, as well as foundry furnace jackets, doors and panels and other heat treating and induction hardening equipment.

The flow transmitters are electronic instruments with wetted parts entirely of polyvinyl chloride (PVC). The meters are designed to transmit low-viscosity fluids that are compatible with PVC, including water that may contain particles. Unlike mechanical switches, the meters eliminate potential for clogging.

P420 Series flow transmitters from Universal Flow Monitors are offered at paddlewheel-meter pricing without the need to replace paddlewheels. The non-mechanical meters start at $325 (U.S.) list price.

The P420 flowmeters are available in five pipe sizes with maximum flow rates as follows: 1/2 inch ( 12 GPM, 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).

P420 vortex-shedding flow transmitters have no o-ring seals. Connection is made by either solvent welding PVC pipe into the socket port provided or 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.

Product literature for the P420 flow rate transmitter is offered on the Universal Flow Monitors website, www.flowmeters.com. The literature and other additional P420 information is available by scrolling to “The Non-Paddlewheel OEM Meter” on the homepage.
