1/2" NPT Flow Switch, Low Flow

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 pipe sizes greater than 1 inch trade size. Features and BenefitsType 4 (NEMA) enclosure allows use in indoor or outdoor applications. Viton® diaphragms allow use in fluid lines carrying chlorinated water, treated water, or other nonhazardous fluids Low-flow operation on low-flow models actuates switch with less than 1.0 GPM (3.8 L/min) flow for water applications or 9.0 GPM (34.1 L/min) flow for steam applications. Maximum fluid pressure of 290 psig (20 bar) permits use in a wide range of pressure flow conditions. Low-flow model flow switch with Type 3R (NEMA) enclosure; 1/2 in. x 1/2 in.
