F261 Series Fluid Flow Switches

The F261 Series Flow Switches respond to fluid flow in lines carrying water, ethylene glycol, or other nonhazardous fluids. These models also work in applications with swimming pool water and lubricating oils. F261 Series Standard Flow Switches use a variety of paddle sizes to respond to fluid flow rates in applications with 1 inch trade size (or greater) pipe. F261 Series Low Flow Switches respond to low fluid flow rates in applications with 1 inch trade size (or less) pipe. A low-energy model with gold-plated contacts provides improved electrical performance in low-voltage, low-current circuits (dry circuits) to switch low-energy resistive loads, such as control signals.
