LEAK RATE/OPERATING PRINCIPLE/MAX
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.
Vacuum Leak Monitoring System
vacuum generated by a vacuum pump to continuously maintain and
monitor up to 4 zones. The console also has a learn function that
is used during setup to determine the time to establish the vacuum
on the interstice to a specific level. The time to establish the
vacuum during the learn process is stored by the console and is used
to determine if there is a liquid or air leak whenever the vacuum
needs to be re-established at any time.
System also has a float
valve that is designed to detect the presence of liquid between the
interstice and the vacuum pump.
Volume of monitored interstitial
space must not exceed 2,400 gallons to satisfy 30-day release

System is designed to activate a visual and acoustic 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 piping. / Not applicable
