Flow Switch

The Compact Flotect® Flow Switch is a weatherproof, NEMA 4 device designed for 1/2 to 2-inch pipes, ensuring reliable flow monitoring for liquids, gases, and air.

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 FST-200 flow switches use thermal dispersion technology to create a very accurate and economical method of sensing flow. Monitor fluids from 0.4 to 1.2 specific gravity.

The FSW-160 is the newest heavy-duty line of flow switches.The switch is used to signal,start,or stop electronically operated equipment when flow or no-flow conditions occur.

The Vane Flow Switch is designed for 1-6 inch pipes, ideal for chemical and HVAC applications. It ensures equipment protection with excellent durability and chemical resistance.

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 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-25 flow switch utilizes the force of liquid flow to propel its paddle and to detect the incoming flow or movement of the existing liquid in the pipe.

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.
