F61 Series: Flow Switch (Standard Flow Rate - SPDT)

F61: Flow Switch Standard

Description

  • The F61 Series Flow Switches are Single- Pole, Double-Throw (SPDT) flow switches used on fluid lines carrying water, ethylene glycol, or other fluids not classified as hazardous. They can be wired to energize one device and de-energize another device powered from the same source when fluid flow either exceeds or drops below the set flow rate.
  • The F61MG type flow switches are used for low-energy loads to operate small relays, solenoid valves, and electronic control circuits. These flow switches have gold-plated contacts for improved electrical performance in low voltage, low current circuits.


Features

  • Stainless steel paddle has three segments for use in pipes from 1 in. to 3 in. (25 mm to 75 mm) diameter.
  • Paddle segments can be removed or trimmed as needed.
  • F61KB-11 and F61MB-1 include a 6 in. (152 mm) paddle for pipes 4 in. to 6 in. (102 mm to 152 mm).
  • Gold-plated contacts on F61MG-1 reduce intermittent contact problems in lowvoltage and low-current circuits.


Applications

  • Use on lines carrying water or ethylene glycol.
  • Not for use with hazardous fluids or in hazardous atmospheres.
