Flow Switches

The Flotect® Flow Switches provide reliable low flow protection in weatherproof and explosion-proof designs. Ideal for safeguarding pumps and systems in demanding environments.

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 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 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 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 Thermal Dispersion Flow Transmitter features a durable 316L stainless steel design, ideal for measuring flow in pipes from 1/2" to 2". Perfect for chiller and boiler systems.

The Air Flow Switch monitors duct air flow and comes with a mounting bracket for easy installation. It is used for fan, filter, and air handler monitoring.

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 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 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 Flotect® Flow Switch for Liquids is a reliable NEMA 4X device designed for boilers and pumps, ensuring safe operation by detecting flow conditions in various applications.

The Adjustable Air Flow Paddle Switch features a stainless steel vane and a durable design, perfect for detecting air flow in HVAC systems with minimal calibration.

The P2 Flow Switch features a compact piston design for air and pure water applications, with FDA compliant materials, ideal for monitoring filter life and cooling systems.

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

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 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 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.

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 Air Flow Indicator & Alarm alerts you to low air flow in radon mitigation systems. It features an 85 dB alarm, bright LED alerts, and is battery-powered for easy installation.

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.
