Flow Switch

The FS-100-Series offers low cost flow monitoring with a variety of switch actuation points and low pressure drop. All wetted parts are polypropylene.

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

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-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 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.
