FLOW SWITCH Features

Fixed Set-Point Flow Switches

Our 30000 Series fixed set-point flow switches have factory-preset settings. The many features and the adjustability found on our other models have been designed out.

The compact size and basic profile of these flow switches results in a low-cost switch that can be mounted where space is limited. This makes these flow switches popular for OEM applications where simple flow switch actuation is required.

Rugged materials are used to allow for long-term, high-pressure use. Our flow switches are popular for portable systems where shock and vibration are common. Stainless steel springs and brass or stainless steel pistons and pressure bodies allow these flow switches to be used in a variety of applications, including lubricating systems, chillers, coolers and heat exchangers.

How a Flow Switch Works

Designed for in-line use, the fluid enters the end connection and exits the side port. As the fluid passes through the flow switch it pushes against a spring-loaded piston magnet sensor. As the sensor magnet moves into proximity of the reed switch, the switch is activated.How a flow switch Works

Flow Switch Calibration

Flow switches are calibrated on increasing flow in the vertical position on water at 70 F. For other fluids or conditions special calibration is available. In this case, specify orientation, fluid, specific gravity and viscosity.
