Universal Hydrostatic


Universal Hydrostatic

The UHS uses float switch technology to continuously monitor liquid-filled double wall containment sumps. Normally submerged, the single float UHS will provide an indication if there is a loss of monitoring liquid.

Electro-Optic Interstitial Sensor

  • Highly reliable float technology and closed output circuit ensures that leaks are detected.
  • Chemical-resistant materials.
  • Each UHS sensor comes with a 25' (7.6 m) cable. The sensor can be installed into the reservoir of a liquid filled double wall containment sump. The sensor must be installed in a vertical position at a level where it is normally submerged. The UHS  sensor will alert if the liquid level drops below the bottom of the sensor.

No matter what the monitoring application is, Franklin Fueling Systems offers a sensor solution tailored to the specific requirements of each application.

Let us help you choose the right sensor for your application.

  • Typically used for hydrostatic monitoring of the liquid in a double wall sump interstice.
Model Number Description
FMP-UHS Universal hydrostatic sensor (all EVO™ Series ATGs)
TSP-UHS Universal hydrostatic sensor (for use with S940 only)
HM-KIT Hydrostatic monitoring installation kit. Includes: flexible brine tube, sensor housing clamp, sensor housing, sensor cap, and hardware
  • Note: Both the FMP-ULS(or UHS) and TSP-ULS(or UHS) can communicate using two wires on the 2-Wire Sensor Module or the 3-Wire Sensor Module. They cannot be wired to the probe module.
