water flow switch

Features Simple structure ,low cost the vane indefatigability low flow rate movement.

Application

FS water flow switch is widely used for situations need water-break protection ,such as air conditioning,freezingImported reed switchUsed for testing flow position of liquid flowing through pipeline .Can be installed on level or Vertical pipe,but there must be straight line lenghth more than 5 times of pipe diameter at the two sides of the switch .
