Smart Sensor Equipped with Intellisense™ Technology

Description
The primary function of the single-level sensor is to sense liquid in sumps, fuel dispenser pans and other
locations where there is liquid that could indicate that a leak has occurred. A float inside the sensor moves up
when the liquid level increases. The float switch will operate and cause an alarm condition in the controller. If
there is a break in the cable it will cause an alarm condition in the system.
