Leak Detection of Petroleum Double-Wall Tank

[davster01]

Hi,

There seems to be many methods of continuously monitoring an aboveground double-wall tanks for leaks. We were thinking of using a Veeder-Root TLS 350 for both piping and the tanks.

These are a couple of 10 000 liters tanks feeding a power generator that is running continuously.

The question I have is what is the best way (lowest maintenance) for monitoring the tanks? Should I look at the pressure in the interstitial space, or at the presence of hydrocarbon in the interstitial space or at the variation of liquid volumes inside the primary tank (hydrocarbon and water).

Thank you

I thought double wall tanks all came with float switches in the interstitial space.

Hi Davster01,

I also suggest you look at the new OPW iSite,

The iSite gives you various options for monitoring the interstitial spaces.

In my opinion, the lowest maintenance unit would be a duel hydrocarbon/water sensor.
