Dwyer HFO In-Line Flow Alarms provide continuous monitoring and control of flow rate levels. The flow alarm can be configured to open or close contact for an increasing or decreasing set point. Available in 1/4″, 1/2″, 1″ or 1-1/2″ female NPT process connections, in aluminum, brass or 304 SS body.
Flow includes Flow Transmitters, Flow Sensors, Flow meters, Sight Flow Indicators and Water Meters. Mass Flowmeters, Controllers, Flow Indicators and Controllers are ideal for the measurement of flow rates.
Flow Switches come as a 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 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, wastewater processing, lubrication systems, drain lines, process control, and pump testing.
