  • Cable gland PG 11 gland. 

Johnson Controls Mechanical liquid flow switch

The F61 liquid flow switches can be used in liquid lines carrying water, 

sea water, swimming pool water, ethylene glycol or other liquids not 

harmful to the specified materials. 

The switches have SPDT contacts and can be wired to energise one 

device and de-energise another when liquid flow either exceeds 

or drops below the set flow rate. Pipe insert models and the T-body 

types for low-flow applications are available. 

The IP43 versions can be used for liquid temperatures above dewpoint 

Typical applications are to shut down the compressor on liquid chiller 

systems, to prove flow on electric immersion heaters and to give 

a signal or alarm when the pump on condenser cooling system shuts  down. 

Pipe-insert types

To allow the switch to detect changes in the liquid flow, the paddle must not touch the pipe or any other obstacle in the pipe. 

The Pipe-insert types are mounted on top of the liquid line. 

An angle of 120° is allowed as indicated in Fig. 1.

To keep the flow switch close to the pipe and to provide an adequate paddle length in the flow

stream the use of a reducing tee for larger pipe sizes is advised. 

The arrow on the cover must point in the flow direction. 

To avoid turbulence it is advised to mount the controller at a distance

of minimal 10xD (on each side) away from elbows, valves and other appendages. 

The Pipe-insert types can be mounted in a vertical pipe as long as the flow is up-stream. 

This mounting position affects the adjustment of the controller.

The 6” paddle can be trimmed as indicated on page 6. 

For added stiffness it is advised to mount the smaller paddles behind the largest one

The switches are factory set at minimal flow setting. 

On the application the setting can be adjusted by the range screw under the cover as

indicated in fig. 3. For higher flow rates turn the adjusting screw clockwise.
