A Secondary Containment Vacuum Sensing System for use with VeederRoot’s ATG Systems. The Secondary Containment Vacuum Sensing (SCVS) System is designed to detect leaks in doublewalled tanks and piping systems while helping to contain a release of product while under vacuum. The system consists of: • Vacuum Sensors, connected to tank, sump or piping interstices • A Submersible Turbine Pump (STP), to provide a source of vacuum • A Smart Sensor Interface with Embedded Pressure Module in a TLS-350 Monitoring System The Vacuum Sensor is interfaced to VeederRoot's TLS-350 Monitoring System via intrinsically safe wiring to provide system status, replenish rate, alarm, and diagnostic information. Vacuum Sensor Kits are available in a variety of models: • For monitoring double-walled piping and sump interstices • For monitoring double-walled steel tank interstices (see back page) • For double-walled fiberglass tanks These kits differ in the number of vacuum sensors and the configuration of associated liquid sensors. An inline kit mounted liquid sensor is used for Vacuum Sensors monitoring piping and sumps. An external liquid sensor (to be installed in the secondary space at the bottom of the tank) is provided with one of the Vacuum Sensors in the steel and fiberglass tank kits to monitor the tank. Maximize protection with a vacuum monitored secondary containment system. Operating Temperature Rating: -25 degrees C to +70 degrees C Cable Length: 8 feet Sensor Dimensions: 5” high x 5” wide 2” deep Console Capability The Vacuum Sensor is compatible with the following consoles: Console TLS-350R/EMC w/BIR* TLS-350 Plus/EMC Enhanced* TLS-350/EMC* *Upgrade Note: The Vacuum Sensor System requires the console to have version 24C software (or greater) along with an ECPU2 or ECPU w/ NVMEM 1 board.
