Dwyer Series FS Flow Meter with Flow Limit Switch | Descriptions

Flow includes Flow Transmitters, Flow Sensors, Flow meters, Sight Flow Indicators and Water Meters. Mass Flow meters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston. Flow meters indicate flow rate. The different sensors include dial, in-line, ultrasonic, orifice plate, totalizing meters, variable area, venturi, or with switch output. The different designs of the flow meters have a variety of applications.

Flow indicators with an electrical contact output at a specific flow rate with switch output. Applications include chemical processing, waste water processing, lubrication systems, drain lines, process control, and pump testing. Series FS Flow Meter with Flow Limit Switch offer visual flow rate indication and an adjustable flow alarm to close AC electrical circuits, trigger warning lights, or activate other process control equipment. Spring-retained movable piston design allows installation in any position.
