F261 Series Fluid Flow Switches

Description

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.

Refer to the F261 Series Fluid Flow Switches Product Bulletin (LIT-12011987) for important product application information.

Features

•Type 3R (NEMA) or Type 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	F261 Flow Switch
pressure flow conditions.

		Repair Information
		If the F261 Series Flow Switch fails to operate
		within its specifications, replace the unit. For a
		replacement F261 Series Flow Switch, contact
		the nearest Johnson Controls®
		representative.

1.Ensure that the low liquid temperature combined with the low ambient temperature does not lead to the freezing the liquid inside the body (or bellows, where appropriate). Please observe the liquid freezing point.

2.At higher ambient temperatures, the maximum allowed liquid temperature becomes lower. The temperature of the electrical switch inside should not exceed 158°F (70°C).
