Digital Paddle-Wheel Flowmeters

Enhanced digital paddle-wheel flowmeters are designed to offer cost-effective solutions to medium-flow liquid applications. Access is password-protected to eliminate user-tampering or resetting. Flowrate readings can be displayed in 23 different volumetric or mass-flow engineering units. Parameters and functions can be programmed locally via an optional keypad with a liquid crystal display interface, or remotely using an RS-232/RS-485 interface. These flowmeters support various functions, including two independently programmable flow totalizers, a self-diagnostic alarm, flow-pulse output, and analog 0–5-VDC or 4–20-mA output flow and temperature signals. The units are constructed of polypropylene or chemically resistant polyvinylidene fluoride (PVDF), and they can be mounted either horizontally or vertically. They are designed to be used in metering, test stand, original equipment manufacturer (OEM), water treatment, water dispensing, flow verification, and process applications.
