Technology Overview: Precision Line Leak Detection

Tanknology Canada's precision line leak testing technology is Underwriter's Laboratories of Canada (ULC) approved. This third party approval indicates that the technology is capable of level one leak detection. The system is used to test product delivery lines associated with storage tank systems. When administered by Tanknology's trained technicians it is the most effective way to detect even very small leaks. The system is based on the simple principle that liquid fuel does not compress when placed under pressure. The line is pressurized with product. If the line is leaking the testing apparatus measures the amount of liquid which exits the line through a leak and is timed to determine a leak rate.

The testing apparatus is attached to the line at the union underneath the pump. The line is then overfilled into the tester and a pressure of one and one half times the operating pressure of the line is applied. The level of liquid is noted in the graduated cylinder of the testing apparatus. Liquid level readings are then observed at ten minute intervals. This allows the technician to calculate a leak rate in litres per hour.
