Xerxes Corp.

Xerxes Trucheck Continuous Leak Detection System


Certified as a continuous, brine-filled interstitial space leak detection system for tanks up to 30,000 gallons manufactured by Xerxes, Corp.

Operating Principle:
A Fluid reservoir is attached to the top of the tank and is open to the interstice through the bottom and is filled with a brine solution. The reservoir is equipped with an electronic probe to provide for low level and high level alarms.

Alarm Conditions:
The brine level is set at 5 inches above the low level alarm. The low level alarm will sound for reservoirs of 18, 24 or 36 inches diameter in 5, 9 and 19 days respectively. Under average conditions, leaks of 0.009, 0.015 or 0.032 gal/hr will trigger the low level alarm in 30 days for the same three reservoirs, respectively. If the brine level is originally higher than 5 inches above the low-level alarm point, the alarm time will be proportionally longer and the leak detection value in thirty days will be proportionally longer.

Xerxes Corp. underground double-walled storage tanks as specified above containing gasoline, gasohol, diesel, heating oil #2, kerosene, aviation fuel, or motor oil. Other liquids may be stored after consultation with the manufacturer.

Manufacturer's Specifications:
Fluid in reservoir must be filled to proper level.

The method must be used with a dual-point sensor system that will properly fit into the reservoir, is compatible with the interstitial liquid, and is on the NWGLDE list.
