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

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 FSW500 offers low cost flow monitoring with a variety of switch actuation points and low pressure drop. All wetted parts are polypropylene or stainless steel.

The FSW-420/30-Series monitors your relative flow rate for applications where the actual flow rate is not important. The FSW-420/30-Series is easy to install and use.

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.

The Series V10 Flotect Mini-Size Flow Switches is designed to provide inexpensive, reliable monitoring of the presence or absence of flow in a system.

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 Series V6 Flotect® Flow Switch is surprisingly compact, and specifically engineered to monitor liquid, gas, or air flows.

The Series FS-2 Vane Flow Switches offers an economical flow proving solution. The FS-2 paddles are adjustable to fit 1 to 8" size pipe.

The FST1000-Series measures air velocity and provides two SPST contact closures corresponding to high and low alarm set points. The alarm set points adjust from 0 to 100%

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.

The FLCN-110 offers adjustable time delay relays, invert switch, and LED status enunciators all maximize the flexibility of this powerful controller.

The FSW-140-Series flow switches offer superior performance. Their fixed set-point make it a dependable switch. This-Series is an ideal choice for coolant applications.
