Octal Socket

        Octal socket type conductivity level switches have a single relay with one set of dry

contacts.  These tank level sensors are ideal for single point on / off switching or filling and

emptying operations.  The Paneleveline™ series is specifically designed for panel builders

and contractors although it can be mounted in a polycarbonate or 304 s.s. housing and

used as a stand alone control.
