Flow-meter Aalborg Instruments

Aalborg®'s multi-parameter PWE Enhanced Digital Paddle Wheel Flow Meters offer cost-effective solutions to medium flow liquid applications. Password-protected access to process parameters eliminates user-tampering or resetting. Flow rates can be displayed in 23 different volumetric or mass flow engineering units. In addition, flow meter parameters and functions can now be programmed locally via optional key pad and LCD or remotely via RS-232/RS-485 interface.

Simple in design with only one moving part, these units are easy to install & operate. Sapphire jewel bearings facilitate virtually friction-free impeller wheel rotations resulting in linear medium flow metering. PWE supports various functions including two independently programmable flow totalizers, self-diagnostic alarm, flow pulse output, and analog 0-5Vdc or 4-20 mA output flow & temperature signals.

Models constructed of Polypropylene or chemically-resistant PVDF can be mounted either horizontally or vertically. Designed for measuring highly accurate temperature readings, PWE Digital Paddle Wheel Meters are ideally suited to many flow system applications. Durable materials of construction ensure long operational life.
