F61 Series Flow Switch (Low Flow Rate - SPDT)

F61 Series: Low Flow Rate Switch

Description

For use on liquid lines using water, ethylene glycol solutions, or other liquids not injurious to the brass and phosphor bronze parts. The SPDT contact switch is activated by a low flow rate; however, it has a large flow capacity with a minimum pressure drop.

Applications

  • Water purification and treatment systems.
  • Booster pumps.
  • Fast shutdown on high input boilers to guard against circulation failure.
  • Cooling systems for electronic tubes, bearings, and compressors.
