Flow Switches

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 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-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 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-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 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%

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.

Flow Switch Remote Controller

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.

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 Series BFM Bulk Flow Monitor ensures reliable flow detection in pipes and chutes. With adjustable sensitivity and no maintenance, it's ideal for various applications.

The Series V10 Mini Flow Switches monitor flow in 1/2 to 2-inch pipelines. Available in brass or stainless steel, they ensure reliable performance for various applications.

The Series FS-2 Vane Flow Switch is designed for boilers and heaters, adjustable for 1-8" pipes. Ideal for flow proving in various applications, featuring durable aluminum housing.
