Jet-Flo Flow Switch FS51-11

The Jet-Flo FS51-11 Flow Switch is a liquid flow detection switch designed to monitor water flow inside pipelines. It automatically detects changes in flow and triggers an electrical signal to start, stop, or protect equipment such as pumps, compressors, or cooling systems.

This switch is commonly used for no-flow protection in systems like water pumps, cooling systems, and pool equipment. When the liquid flow drops below or rises above the set value, the switch activates its internal contacts to control connected electrical devices and prevent system damage.
