A flow switch is a mechanical device that detects the presence or absence of liquid flow in a pipe. It sends a signal—usually electrical—when fluid begins or stops moving. Flow switches are essential for protecting pumps, monitoring cooling systems, and automating flow-based processes.
The Type R20 uses a flap mechanism and a reed contact switch to sense the flow. It connects to systems through a ½” BSPP male thread, allowing easy integration into pipelines.
Flap Design – Responds quickly to liquid movement
Reed Switch Contact – Provides safe and accurate signal output
½” BSPP Male Thread – Fits standard pipe sizes for easy installation
Compact Size – Ideal for tight spaces and small systems
Reliable Performance – Works with clean water and similar fluids
Low Maintenance – Simple internal mechanism, long service life
The Type R20 flow switch is suitable for many industries and use cases, such as:
Water pipelines and pumping systems
Cooling circuits in HVAC systems
