VEEDER- ROOT <br /> Secondary SensingSimplify • • - • n with a vacuum monitored secondarycontainment . <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 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 /> is included in the pre-assembled Vacuum Sensor Monitoring Kits. Certified to meet California's requirement for secondary containment <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-450 PLUS 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 . TLSE <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 />
