r4he):� VEEDER- ROOT <br /> Secondary Containment • System <br /> ComplianceSimplify • • n with a vacuum monitored secondatycontainment. <br /> The Importance of SCVS <br /> a =- <br /> The Secondary Containment Vacuum Sensing System <br /> (SCVS) for the TLSA50PLUS Automatic Tank Gauge (ATG ) P - <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 /> i, <br /> I <br /> SYSTEM REQUIREMENTS f . FEATURES AND BENEFITS <br /> • Vacuum Sensors connecttotank, 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 <br /> • Universal Input / output Module (UIOM) for pump control. REDUCE EXPOSURE TO RISK <br /> /n 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, j Y <br /> replenish rates, alarms and diagnostic information. <br /> The Vacuum Sensors are manufactured in mountable kits of 1 to 4 31 <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 /> I <br /> monitoring sumps and piping . An external Liquid Sensor (to be installed <br /> at the bottom of the tank interslice) 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 i <br /> Able to share wiring conduit with other Veeder-Root intrinsically safe (IS) <br /> probes and sensors, including surnp and line leak sensors <br /> Provides for positive shutdown of pressurized lines when required <br /> • Simple installation, no need to mess with brine <br /> I <br /> I <br />
