<strong>Flow</strong> <strong>Switch</strong> <strong>10.2.</strong><br />
calorimetric <strong>EFK2</strong> <strong>EFK2</strong>.<br />
GENERAL CHARACTERISTICS<br />
The <strong>Flow</strong> <strong>Switch</strong> EFK 2 controls liquid and gaseous<br />
substances. The instrument combines compact<br />
dimensions, an easy switch setting by potentiometer, a<br />
dual colour LED and a Galvanic insulated switch signal<br />
(NO) or transistor outputs (PNP/NPN). As option, an<br />
inclineable swan neck is available as a connection of<br />
sensor to housing to receive higher temperature ratings<br />
and better reading possibilities.<br />
� compact <strong>Flow</strong> <strong>Switch</strong><br />
� no moving parts in the medium being monitored<br />
� mounting largely independent of pipe diameter<br />

MOUNTING<br />
If you would like to exploit the highest possible sensor<br />
sensitivity (for particularly low flow rates or for use in<br />
gases), orientate the cross on hexagonal body of<br />
probe(liquids) or the red dot (gases) into a position against<br />
flow direction ( flow meets cross or dot). See also the<br />
general description on calorimetric sensors.<br />
