Flotect® Vane Operated Flow Switch Series V8
Field adjustable - 1 to 6 inch pipe. leak proof body.

   
 
   
 

Model V8 Flotect protects equipment from damage caused by inadequate flow of coolant or lubricant, warns and controls when flow is too high. SPDT snap switch can turn electrical devices and alarms on or off with either increasing or decreasing flow rates. Simple, reliable design uses an external magnet to activate switch which is fully protected inside leak-proof body. Both body and vane are made from chemically resistant polyphenylene sulfide. Trimmable vane has molded graduations for 1- to 6-inch pipes. See chart for aproximate flows.
