VEEDER ROOT <br /> Secondary Containment • System <br /> Simplify compliance and maximize protection with a vacuum monitored secondary containment. <br /> The Importance of SCVS <br /> The Secondary Containment Vacuum Sensing System <br /> (SCVS)for the TLS-450 PLUS Automatic Tank Gauge(ATG) <br /> is designed to detect leaks in double-walled fuel tank, <br /> sump and piping systems. It helps contain the release of <br /> product while under vacuum. <br /> SYSTEM REQUIREMENTS r> FEATURES AND BENEFITS <br /> • Vacuum Sensors connect to tank,sump and piping interstices. SATISFY REGULATIONS <br /> Each Vacuum Sensor must have an associated Liquid Sensor,which <br /> Certified to meet California's requirement for secondary containment <br /> is included in the pre-assembled Vacuum Sensor Monitoring Kits. <br /> • Vacuum source-Submersible Turbine Pump(STP)to create suction. monitoring for tanks and lines as required by AB 2481 <br /> • Atmospheric Pressure Sensor(ATM)for measuring ambient pressure. Satisfies the requirements for Class 1 Leak Detection as defined by the <br /> • Universal Sensor Module(USM)for sensor inputs. European Standard EN 13160-2 <br /> • Universal Input/Output Module(UIOM)for pump control. REDUCE EXPOSURE TO RISK <br /> In certain markets,monthly inspections and three-year sump integrity TLS-450PLUS alarms when the vacuum cannot be maintained or when <br /> tests are not required when the Veeder-Root Secondary Containment replenish rates exceed 85 liters per hour <br /> Vacuum Sensing System is used. The system alarms when liquid is detected in the secondary space <br /> Facilitates periodic operability testing <br /> The Vacuum Sensors are connected to a TLS-450PLUS ATG,via <br /> intrinsically safe(IS)wiring.The TLS-450PLUS provides system status, <br /> replenish rates,alarms and diagnostic information. <br /> f <br /> i <br /> The Vacuum Sensors are manufactured in mountable kits of 1 to 4 - <br /> sensors available for monitoring: <br /> Double-walled sump and piping interstices <br /> Double-walled steel tanks <br /> • Double-walled fiberglass tanks <br /> An inline kit mounted Liquid Sensor is used for Vacuum Sensors <br /> monitoring sumps and piping.An external Liquid Sensor(to be installed <br /> at the bottom of the tank interstice)is provided with Vacuum Sensors LEVERAGE EXISTING VEEDER-ROOT SYSTEMS <br /> for steel and fiberglass tank kits. <br /> • Uses Red Jacket'STP as the vacuum source <br /> • Installs in the STP sump <br /> • Able to share wiring conduit with other Veeder-Root intrinsically safe(IS) <br /> probes and sensors,including sump and line leak sensors <br /> Provides for positive shutdown of pressurized lines when required <br /> • Simple installation,no need to mess with brine <br /> www.veeder.com <br />
