Flow switch

an independently mounted water flow sensing device that makes or breaks an electrical circuit when flow stops or starts

The paddle type flow control F61KB series aredesigned to provide excellent performance whereaccuracy, reliability, and rugged construction arerequired in liquid flow lines carrying water or anyfluid neither harmful to brass and phosphor bronzenor classified as a hazardous fluids. The SPDTmicro-switch can be wired to close one circuit andopen a second circuit when liquid flow eitherexceeds or drops below the adjusted flow rate.The F61KB series are recommended for liquidpressure and temperature as mentioned below andmust not be used on lines carrying liquids below 0deg. C. These series may be used on liquids withhigh salt or chlorine content but is not for used inhazardous atmospheres. They may be also usedoutdoors but must be protected from weather orsplashing water. All series F61KB flow switched aredesigned for use only as operating controls. Wherean operating control failure would result inpersonal injury and/or loss of property, it is theresponsibility of user to add safety devices thatprotect against, or add supervisory systems thatwarn of control.
