The Importance of SCVS <br />The Secondary Containment Vacuum Sensing System <br />(SCVS) for the TLS-450PLUS 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 />Secondary Containment Vacuum Sensing System <br />www.veeder.com <br />Simplify compliance and maximize protection with a vacuum monitored secondary containment. <br />SYSTEM REQUIREMENTS <br />SATISFY REGULATIONS <br />REDUCE EXPOSURE TO RISK <br />LEVERAGE EXISTING VEEDER-ROOT SYSTEMS <br />• Vacuum Sensors connect to tank, sump and piping interstices. <br />Each Vacuum Sensor must have an associated Liquid Sensor, which <br />is included in the pre-assembled Vacuum Sensor Monitoring Kits. <br />• Vacuum source - Submersible Turbine Pump (STP) to create suction. <br />• Atmospheric Pressure Sensor (ATM) for measuring ambient pressure. <br />• Universal Sensor Module (USM) for sensor inputs. <br />• Universal Input / Output Module (UIOM) for pump control. <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 />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 <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 />• <br />In certain markets, monthly inspections and three-year sump integrity <br />tests are not required when the Veeder-Root Secondary Containment <br />Vacuum Sensing System is used. <br />• <br />monitoring for tanks and lines as required by AB 2481 <br />• <br />European Standard EN 13160-2 <br />• TLS-450PLUS alarms when the vacuum cannot be maintained or when <br />replenish rates exceed 85 liters per hour <br />• The system alarms when liquid is detected in the secondary space <br />• Facilitates periodic operability testing <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 />FEATURES AND BENEFITS
