Monitoring Well


Monitoring Well

The monitoring well sensor (MWS) is a discriminating liquid sensor which detects the presence of hydrocarbons floating on groundwater. Using a float switch and innovative conductive polymer strip, the sensor identifies hydrocarbons anywhere along the length of the sensor. The MWS sensor can be used with EVO™ 550 and EVO™ 5000 fuel management system ATGs.

Monitoring Well Sensor

  • Unique alarms for the detection of hydrocarbons or decreased groundwater levels.
  • Completely reusable even after several exposures to hydrocarbons.
  • Available in four different lengths to accommodate well depth.
  • Microcomputer within TSP-MWS detects presence of hydrocarbons and alerts Tank Sentinel® and fuel management system of alarm conditions via digitally-encoded information.


  • For use in wet monitoring wells.


  • Normally installed in 4" (102mm) groundwater monitoring wells.
  • Integral well cap may be locked with standard padlock to prevent unauthorized access.
