Johnson Controls F61KB-11C Liquid Flow Switch
The Johnson Controls F61KB-11C is a heavy-duty, standard-action liquid flow switch designed to accurately detect flow rate variations in pipelines. Functioning as a Single-Pole, Double-Throw (SPDT) snap-acting switch, this unit can be wired to simultaneously energize one device and de-energize another whenever fluid flow either exceeds or drops below the user's customized set point.
Engineered for lines carrying water, ethylene glycol, or other non-hazardous liquids, it is widely utilized to safeguard refrigeration compressors against chiller freeze-ups, manage booster pumps, and monitor liquid flow in water treatment or cooling systems.The F61KB-11C features a fully adjustable range screw for precise field adjustment.It comes complete with a versatile 3-piece segmented paddle (1", 2", and 3" segments) pre-installed, plus an uninstalled 6" paddle, allowing it to adapt to pipe sizes from 1" up to 6" in diameter.
