Universal Liquid Sump


Universal Liquid Sump

Based on float-switch technology and made of chemically-resistant materials, the ULS is a low-cost sensor that can be installed in sumps, dispenser pans, steel double wall tanks or other locations where the presence of liquid indicates a leak has occurred.

Universal Liquid Sensor

  • Highly reliable float technology and closed output circuit ensures that leaks are detected.
  • Chemical-resistant materials assure compatibility with most liquids.
  • Each ULS sensor comes with a 25' (7.6 m) cable. 1/2" NPT thread is provided on the compression gland fitting attached to the sensor’s cable, allowing it to be suspended from standard electrical boxes and fittings. The sensor may be positioned vertically by adjusting cable length. For steel interstitial tanks, ULS is lowered into the opening provided on the tank and is suspended by optional TSP-KI2 installation kit. Other mounting methods available depending upon application and location.

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