SECONDARY
CONTAINMENT
MONITORING
The secondary containment monitoring (SCM) system
is designed to detect leaks in double-wall piping, tanks,
and sumps. The system utilizes the syphon/vacuum
port of a submersible turbine pump to draw a vacuum
on these interstitial spaces. The vacuum levels are then
continuously monitored to detect any potential leaks in
these double-wall containments.
SPECIFICATIONS
• Up to four different containments can be connected to
each submersible turbine pump using a combination of
single and dual channel TS-SCCM secondary containment
control modules and secondary syphon ports.
• Operating vacuum level: -2 to -6 in Hg
• The secondary containment control module collects
information on all interstitial spaces.
• Gathers system status, replenish rate, alarm, and
diagnostic information.
• Utilizes AUTO-LEARN® technology to learn the
actual interstitial space being monitored based on the
vacuum flow rate through a calibrated orifice for precise
leak detection.
• Alarms when vacuum cannot be maintained or when liquid
is detected in secondary space.
• Optional positive submersible turbine pump shut-down
upon alarm.
• Available software option on EVO™ 550 and EVO™ 5000.
• TS-420IB, TS-RLY and TS-ACI modules and the TS-SCM
software option must be ordered and installed in the tank
gauge ATG.
• Requires TS-SCCM secondary containment control module
consisting of pressure sensor(s) and solenoid valve(s).
• Requires syphon check valve to connect to STP manifold.
• Containments to be monitored must terminate inside the
submersible turbine pump containment.
• Installer must verify the vacuum limitation of each
containment with its manufacturer prior to installation.
Approvals/Certifications
• Meets all requirements of California AB2481.
• Compatible with FE PETRO® brand submersible turbine
pumps as well as Red Jacket® STPs.
• National Work Group approved.
• All components necessary for installation including syphon
check valve,vacuum hose, fittings and other installation
accessories are available from Franklin Fueling systems.
Secondary containment monitoring uses the siphon port of
the submersible turbine pump to draw and maintain a
vacuum on the secondary containments of lines, sumps,
tanks and vapour lines. During installation a calibrated leak is
introduced during the AUTO-LEARN® process which allows
the system to learn the vacuum characteristics of each
containment space. The vacuum level is continuously
monitored and compared to established leak rates to ensure
that the secondary containment is tight.
Note: Product compatible with EVO™ 550 and EVO™ 5000 only.
