OPERATING PRINCIPLE/

MAX TANK CAPACITY

Beaudreau Electric, Inc. SystemOne 522T Monitor Not Determined/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. System is capable of detecting breaches in both the inner and outer walls of double-walled tanks and double-walled piping./Not applicable

Bell Avon, Inc.

VIGILANT Leak Detection System

0.1 gph/ System alarms when changes in interstitial vacuum exceed a predetermined change in slope versus time curve./15,000 gallons

Core Engineered Solutions

Safesite Vacuum Interstitial Monitoring System

0.1 gph / System uses vacuum generated by a vacuum pump or submersible pump to continuously maintain a partial vacuum of 7.5 psig, equivalent to 207.6 water column for a period of 60 minutes, and maintain vacuum for 30 seconds prior to testing. System is designed to activate a visual and acoustic alarm, and optional submersible pump shutdown before stored product can escape to the environment. System was evaluated for detecting breaches within the interstitial space effective gap of 3/64 or greater of a double-walled tank or double-walled piping. / 270 gallons or 5,690 feet of piping.

Franklin Fueling Systems Secondary Containment Monitoring (SCM) - Incon TS-SCM and EBW AS-SCM Not Determined/System uses vacuum generated by the turbine 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.
System is capable of detecting breaches in both the inner and outer walls of double-walled tanks and double-walled piping./Volume of monitored interstitial space must not exceed 8 m3 (2114 gal) for tanks and 10 m3 (2642 gal) for piping.

HT Technologies, Inc.

Vakumatik Models V 60, V 70 Ex

0.1 gph/ System alarms when liquid enters interstitial space and vacuum decreases (pressure increases) above 34 millibars./20,000 gallons

OPW Fuel Management Systems (originally listed as Advanced Fuel Filtration Systems, Inc.) Continuous Vacuum Monitoring System (CVMS)

Not Determined/System uses vacuum generated by the turbine pump to continuously maintain a partial vacuum within the interstitial space of double-walled tanks and double-walled piping.
