Continuous Leak Detection System
CONTINUOUS
INTERSTITIAL MONITORING METHOD (LIQUID FILLED)
Certification:
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.
Applicability:
Xerxes Corp.
underground double-walled storage tanks as specified above containing gasoline,
gasohol, diesel, heating oil #2, kerosene, aviation fuel, or motor oil.
Manufacturer’s
Specifications:
Fluid in reservoir must be filled to proper level.
Comments:
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.
