FLOW SWITCH FOR LIQUID
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 ( for use in other environments see the Product Data Sheet ). 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 .
