Johnson Controls - F61TB-9100 F61 SERIES, FLOW SWITCH, PIPE INSERT, VAPOUR TIGHT IP67,

F61 SERIES, FLOW SWITCH, PIPE INSERT, 20 BAR, VAPOUR TIGHT IP67 RATED

The F61 Liquid Flow Switches are ideal for liquid lines carrying water, sea water, swimming pool water, ethylene glycol or other liquids not harmful to internal materials of the switch. The switch has SPDT contacts and can be wired to energise one device and de-energise another device powered from the same source when liquid flow either exceeds or drops below the set flow rate.

Capable, the F61 flow switch performs easily with a range of applications including the compressor shut down on liquid chiller systems, proving flow on electric immersion heaters and to give a signal or alarm when a condensor pump in a cooling system shuts down

For 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 with the arrow pointing in the direction of flow. Factory set at minimal flow setting, the setting can be adjusted by the range screw under the cover, if you require a higher flow rate turn the adjusting screw clockwise.
