F61 Series Flow Switches
The F61 Series Flow Switches respond to fluid flow in
lines carrying water, ethylene glycol, or other
nonhazardous fluids. Two subseries are available.
F61 Series Sensitive Flow Switches respond to low
fluid flow rates in applications with pipe sizes under
1-inch trade size. (See Figure 1.) Figure 1: F61MD (Left) and F61KD (Right)
Sensitive Flow Switches
F61 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. (See Figure 2.)
Single-Pole, Double-Throw (SPDT) and Single-Pole,
Single-Throw (SPST) open-low versions of these flow
switches are available.

Installation
F61 Series Sensitive Flow Switches do not require
adjustment or installation of paddles prior to mounting
the flow switch.
Some models of the F61 Series Standard Flow
Switches require installation or adjustment of paddles
prior to mounting. See Installing the Flow Paddles.
Parts Included
F61 Series Standard Flow Switches have a
three-piece flow paddle installed at the factory. Some
