Our Type K leak detection gauge is a reliable, vertical type leak monitor engineered to detect leaks in the annular/interstitial space of a double wall above ground containment tank (AST’s).  Its refined mechanical design promotes durability, minimal upkeep, quick installation and quick, inexpensive repairs.

For these gauges, the standard materials we use include a HDPE Float, aluminum rods, aluminum bushing and plastic calibration. Alternative materials of construction such as plastic and stainless are available upon request. Leak detection gauges made of custom materials, however, have smaller size limitations. Our standard interstitial leak gauge monitor can be custom made in house to fit the specifications unique to each customer’s tank.  We can accommodate any size take from 6 inches to 170 inches in depth.

Instructions for Operation

This gauge is a simple visual tool. If the red indicator rises into the viewing window, it is indicating that there is a leak occurring in your double wall containment system. Once installed, you simply view the calibration to monitor your interstitial space. The indicator is not calibrated. It simply indicates leak or no leak.
