plastic material 1/2 bsp magnetic water  flow switch

A flow switch is an instrument that monitors the flow of steam, air, or liquid. The flow switch sends a signal to a device, such as a pump, to turn on or shut off. Flow switches can be used for air conditioning, heating and hydronic systems, among other applications.


Liquid flow switches have a universal design and serve a wider range of applications, such as starting or stopping electrically operated equipment like signal lights, alarms, motors, and automatic burners. In addition, liquid flow switches are used for general purpose applications with environmental exposure or applications requiring a water-tight or dust-tight flow switch. The liquid-flow F61 Series flow switch, manufactured by Johnson Controls, responds to fluid flow in lines carrying water, ethylene glycol, or other nonhazardous fluids. It also responds to low fluid flow rates in applications with pipe sizes under 1" trade size.
