Mag Sump Sensor | Veeder-Root

Mag Sump Sensor

Mag Sump Sensor

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, Veeder-Root’s Mag Sump Sensor produces fast reaction and recovery times, which eliminates costly and unwarranted service calls and sensor replacements. And where it’s allowed, stations can remain open when only water is detected.

The sensor has fast reaction and recovery times which both eliminate costly and unwarranted service dispatches and sensor replacements. This fast reaction and recovery time also allows for quick and easy periodic operability testing if required by local agencies.

Key features:

  • 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 – Fuel Alarm, Water Warning, Water Alarm, Installation Alarm and Communication Alarm are indicated by an audible alarm, a displayed message and a printed message on the TLS / EMC console. They are also recorded as a part of the TLS / EMC console Alarm History Report.

Key Benefits:

  • Full protection with comprehensive alarm conditions
  • Fast fuel and water detection reaction and normal state recovery times
  • Proven industry-accepted magnetostrictive technology
  • Station may not have to shut down if only water is detected (where allowed by regulation)
  • Proper position always monitored to ensure greatest probability of leak detection
  • Alarm history is maintained for compliance reporting where required

Temperature Rating:

  • Storage: -40 degrees C to +60 degrees C
  • Operating: -40 degrees C to +60 degrees C

Cable length: 10 feet

The National Work Group Listing and California Environmental Protection Agency State Water Resources Control Board (Water Quality) have listed the Magnetostrictive Discriminating Level Indicating Sump Sensor (Mag Sump Sensor) as an approved device for use with UST's and associated equipment.

The National Work Group Listing can be viewed at:

The Magnetostrictive Discriminating Level Indicating Sump Sensor may allow stations to remain in operation when only water is detected in the containment sump or pan. The position alarm feature ensures compliance with local ordinances with concern of sensor tampering. The Veeder-Root magnetostrictive technology enables reliable operability testing that is less time consuming than other discriminating technologies.

The California EPA Water Resources Control Board LG 113 listing is at below:

The LG 113 listing allows this discriminating sensor to be used in California in sump and pan applications.
