Reflux Variable Area Flow Transmitter

Product Overview

Reflux Flow Transmitters combine variable area flowmeter and position sensing technology to provide both a direct reading and 4 to 20 mA transmission output in a single unit. This unique approach makes the Reflux Flowmeter an ideal choice for integration into customer equipment.
