Continuous Interstitial Tank System Monitoring Method (Pressure / Vacuum)
Select vendor's equipment name to go to that listing.
Vendor | Equipment Name | Leak Rate/Threshold/Max Tank Capacity |
---|---|---|
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 |
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. |
Fueling and Service Technologies, Inc. (FASTECH) (Originallly listed as Beaudreau Electric, Inc.) | SystemOne 522T Monitor | Not applicable/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./Not applicable |
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 applicable/System uses vacuum generated by the turbine pump to continuously maintain a partial vacuum within the interstitial space of double-walled tanks and piping. System is designed to activate an alarm 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 piping./Not applicable. |
SGB (Sicherungsgeratebau GmbH) | Vacuum Leak Detection System Models VLX 30, VLX 350, and VLX 400 | Not applicable/System uses an integral vacuum pump to continuously maintain a partial vacuum within the interstitial space of a double-walled tank. System is designed to activate an alarm 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./Not applicable |
Vacuum Leak Detection System Models VL 30p, VL 350p, and VL 400p | Not applicable/System uses an integral vacuum pump to continuously maintain a partial vacuum within the interstitial space of a double-walled tank or piping. System is designed to activate an alarm 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 piping./Not applicable | |
Steel Tank Institute | Permatank Interstitial Vacuum Monitor Liquid Leaks | 0.1gph/ A tank system should not be declared tight when the vacuum decreases (pressure increases) 5 inches or more of mercury over the test period specified for each tank size./20,000 gallons |
Veeder-Root | Secondary Containment Leak Detection (SCLD) TLS-350/ProMax/EMC Console with Vacuum Sensors 857280-100, 200, 30x, or Assembly 332175-001 | Not applicable/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./Not applicable. |
