Flow Switch

The FSW800B-Series air-flow monitor provides a simple but reliable alternative to indicate positive or negative air flow of fans.

The FSW-40A and FSW-50-Series flow switches feature 15 A SPDT switches. Their non-magnetic design makes these switches ideal for applications in which rust is a problem.

The FSW-30A flow switches are supplied with six orifices to provide 6 overlapping flow ranges from 0.12 to 8.0 GPM for water. Wetted Parts: brass, 316 SS, phosphor bronze.

The FSW301 flow switch comprises a paddle system with a permanent magnet attached. This construction allows a useful life of up to 100,000,000 switching cycles.

The FSW-6000/7000-Series are thermal flow switch monitors designed to monitor flow status and also used to detect level of liquids, air and gas with visual indication of flow

The FST-320-Series thermal dispersion flow switches, especially designed for use with gases, sense changes in the heat transfer characteristics of the gases.

The FSW-9000-Series is a flow switch monitor that measures the velocity of the flow. The-Series provides two output options: a 4 to 20mA analog output and a PNP/NPN output.

This switch package offers a complete solution for flow or no-flow switching in pipes or ducting up to 12'. The compact relay controller actuates valves, pumps, or blowers.
