Leak Detection Gauge - Type K Interstitial Leak Gauge Monitor

Interstitial Leak Gauge

The Leak Type K Gauge is a reliable, vertical type leak monitor used for detecting leaks in the annular/interstitial space of a double wall above ground containment tank (AST's). Its simple mechanical design promotes durability, minimal upkeep, quick installation, and easy/inexpensive repairs.

This interstitial monitor is custom made in house to fit your tank. We can accomodate any size tank from 6 inches to 170 inches in depth.

If you have a monitoring pipe or have a threaded fitting at the top of the interstitial space on a double wall containment tank, this monitor will thread right in. Any liquid seeping into the containment space will cause the float to rise which will provide a visual indication on top of the tank that there is liquid in the interstitial containment area.

Standard materials include a HDPE float, aluminum rods, aluminum bushing, and plastic calibration.  Alternative materials of construction such as plastic and stainless are available upon request. However, leak detection gauges made of custom materials have smaller size limitations.

Product Update:  In order to achieve enough buoyancy in the past, we used a coated cork float on our larger Leak Gauges.  As of August 2015, we have a newly designed oversized plastic float that has replaced all cork floats that were being used on Leak Gauges.
