Flow Switches

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.

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

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-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 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 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-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-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 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.

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

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.

For operator alert to low flow conditions an amber lens distributes the high intensity strobe light in a pattern which calls immediate attention to alarm conditions.

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