Code No. LIT-1922335 Issued February 1, 2009 F61 Series Flow Switch (Standard Flow Rate – SPDT) Description Series F61 The F61 Series Flow Switches are B Single-Pole, Double-Throw (SPDT) flow switches used on fluid lines carrying water, ethylene glycol, or other fluids not classified Y as hazardous. They can be wired to energize one device and de- energize another device powered R from the same source when fluid flow either exceeds or drops Action on Increase below the set flow rate. of Flow The F61MG type flow switches F61 Series Action Diagram 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 F61MB-1 F61KB-11 performance in low voltage, low current circuits. Features Applications • stainless steel paddle has three segments for use in pipes from 1 in. • use on lines carrying water or ethylene glycol to 3 in. (25 mm to 75 mm) diameter • not for use with hazardous fluids or in hazardous atmospheres • 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 low-voltage and low-current circuits Selection Charts F61 Series Flow Switch (Standard Flow Rate – SPDT) Code Number Enclosure Bellows Paddle F61KB-11C NEMA 1 Phosphor Bronze Stainless Steel; 3-piece Paddle (3 in., 2 in., and 1 in.
