SystemOne 522T Monitor

Continuous Interstitial Tank System Monitoring Method (Pressure/Vacuum)

Certification Certified as equivalent to European leak detection standard EN 13160-2, Part 2, as a Class I leak detection system.
Operating Principle System uses an integral vacuum pump to continuously maintain a partial vacuum within the interstitial space of double-walled tanks and double-walled piping.
System is designed to activate a visual and acoustic alarm, and optional turbine pump shutdown before stored product can escape to the environment, and is capable of detecting breaches in both the inner and outer walls of double-walled tanks and double-walled piping.
Applicability Underground double-walled tank, connected double-walled piping, and other connected interstitial spaces where tank and piping contain gasoline, gasohol, diesel, heating oil #2, kerosene, aviation fuel, or motor oil.
Manufacturer's Specifications The interstitial volume shall not exceed 8 m3 for tanks and 10 m3 for piping.
The interstitial space shall be rated for the maximum operating vacuum level of the leak detector as indicated in the following table, regardless of temperature and groundwater level fluctuations.
Pressure Switch Number Alarm Activation Vacuum Level Maximum Operating Vacuum Level Restrictions
S1-522T-0.9 0.9" Hg (0.44 psi) 6" Hg (2.95 psi) Suction line must be installed at lowest point in the interstitial space.
S1-522T-6 6" Hg (2.95 psi) 12" Hg (5.89 psi)i Depth of interstitial space cannot exceed 6 ft unless the suction line is installed at lowest point in the interstitial space.
S1-522T-8 8" Hg (3.93 psi) 14" Hg (6.88 psi) Depth of interstitial space cannot exceed 8 ft unless the suction line is installed at lowest point in the interstitial space.
S1-522T-10 10"Hg (4.91 psi) 18" Hg (8.84 psi) Depth of interstitial space cannot exceed 10 ft unless the suction line is installed at lowest point in the interstitial space.
Calibration Functional and operational safety tests must be performed annually in accordance with manufacturer's instructions.
Comments Interstitial space is tested continuously.
System is connected to the interstitial space by a suction line and a pressure measuring line.
Vacuum is generated by an integral pump, and is measured and controlled by a pressure switch.
This system may not be compatible with all secondarily contained tanks and/or piping. Always consult with the tank and/or piping manufacturer and the manufacturer's applicable recommended installation practices before installing this system, or damage may be caused to the tank or piping by its use.
