Hi, this is Ben Thomas with UST training, and this is a tank savvy minute. If you have an EVO 550 or 600 by Franklin fueling systems, you want to find out information regarding double wall tanks double wall piping and potentially under dispenser containment or UDC. You click on the little downward arrow button like I showed at the top of the screen you click on the little image that says sensors and wow a lot of sensors going on here. I’m seeing 12 different so what are we looking at here. DISP3/4 that probably means there is under dispenser containment and an under dispenser can sense sump sensor at dispensers three and four. So, I can see dispensers 1 2 3 4 7 8 5 6 a lot of sensors, double wall sensors underneath each dispenser regular STP that means that there is a sump sensor by the submersible turbine above the tank. Likewise there’s one for the premium one for the diesel one for the clear and this says regular INT. That means there’s a double wall interstitial sensor for the tank and there’s a split interstitial sensor here so that’s telling me there’s a bunch of tanks here, they all have interstitial monitoring and so this is the way the system is doing principle and continuous leak detection using interstitial monitoring. And we’re back to here that was sensors come back to home everything you need to know about a Franklin Evo 550 or 600 interstitial monitoring system.
