Perma-Pipe’s PAL-AT is a state of the art leak detection cable system that locates potential problems anywhere along a sensor string. The primary feature of the PAL-AT system is its ability to “map” the entire length of a sensor cable, and then continuously monitor that sensing cable for the presence of a leak. In the event of a leak, a fault condition is registered (and alarmed), and a new map is created. The system then continues to monitor against this new baseline to detect additional release events, or changes in the original event (for example, a leak area that grows in size).
The PAL-AT is often provided for secondary contained fuel-oil pipe systems, or any other application where quick and precise leak detection is required. When applied in a fuel-oil pipe system, the cable sensor is installed within the interstitial space of the secondary containment pipe. The sensing cables are available in non-discriminating types which will sense the presence of water-based and hydrocarbon-based liquids, and they are also offered for hydrocarbon-sensing only (when water-based liquids are to be ignored).
An important feature of the PAL-AT sensing cable is that it can be air-dried and re-used after exposure to a liquid. The cables have no exposed metal parts and can be applied pipe system carrying corrosive chemicals.
Perma-Pipe offers the PAL-AT system in its Type-FS pre-engineered fuel oil piping system, and the product is listed by Florida’s DEP in their Approved Equipment List.

On the containment piping for Fuel Oil on a riser. Just a question what if there is any type of condensation that builds up from heat humidity weather and or cold weather will the leak cable detect moisture and alarm thank you
And if someone could please email me back, that would be great. Just trying to learn about this. not in the underground or horizontal position, but on the vertical, how would it work and like I said with moisture alarm the system.
On a riser (vertical pipe run) we would not recommend a cable-type leak sensor. If wanting to detect any leak accumulating at the bottom of the containment pipe, we would recommend use of both a hydrocarbon-sensing probe, and a second, non-discriminating probe. One will alarm for fuel leaks (critical issue), and the other for any other liquid (less critical). Please reach out to your local sales representative for job-specific application assistance.
