The Mag Sump Sensor is installed in a dispenser pan or containment sump and will detect the presence of, and differentiate between, fuel and other liquids.
Quickly and accurately detect the presence and the amount of water and/or fuel in the containment sump or dispenser pan. Using proven magnetostrictive technology to detect hydrocarbons or water, the Mag Sump Sensor produces fast reaction and recovery times, which eliminates costly and unwarranted service calls and sensor replacements. Its high-grade polymer housing provides enhanced corrosion resistance and fuel compatibility.
The Mag Sump Sensor also allows for quick and easy periodic operability testing using the Sump Integrity Testing feature, if required by local agencies.
Where continuous monitoring of the sensor position is required by law, site owners are immediately notified if the sensor has been moved from its proper position at the bottom of the containment sump or dispenser pan.
Alarm conditions are indicated by an audible alarm and displayed message on the Automatic Tank Gauge console and are recorded as a part of the Alarm History Report.
