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
