CARB Certified Vapor Recovery  

Veeder-Root’s California Air Resources Board (CARB) certified In-Station Diagnostics (ISD) system provides the most accurate vapor recovery detection available in the industry.


The Veeder-Root ISD system continuously monitors the vapor recovery equipment, maintains test records, provides test reports, and generates warnings or alarms following equipment failure. It can now be added to the TLS-450PLUS console, which provides remote access and enhanced security, in addition to the latest features not available on legacy TLS consoles.

Meet Compliance Requirements

  • CARB certified to meet all ISD performance requirements as defined by CP-201, including at least a 95% probability of failure detection while operating at no more than a 1% probability of false alarms
  • CARB certified with all approved hanging hardware
  • Flexible ISD solution certified with multiple Vapor Processor configurations

 

The Most Installed ISD Solution

In California, ISD is required on all gasoline dispensing facilities with an annual throughput over 600,000 gallons. Whether assist or balance vapor recovery, over 90% of California customers have selected Veeder-Root’s ISD system. New stations select the Veeder-Root balance ISD solution due to simpler nozzle alarm requirements.

Veeder-Root’s ISD is the only certified solution that supports all vapor processor configurations and all certified vapor recovery nozzles. Flexible shutdown solutions allow customers to choose between Submersible Turbine Pump (STP) shutdown, single dispenser shutdown, or use both configurations to maximize site uptime.

System Components

  • Vapor Flow Meter – Provides ISD with the volume of vapor recovered during vehicle refueling for continuous vapor collection monitoring
    • Assist Vapor Flow Meter – Designed to withstand the harsh vapor recovery environment found in systems with vapor vacuum pumps
    • Balance Flow Meter – Designed for use in pressure sensitive balance systems to maintain accuracy and minimize false alarms
  • Vapor Pressure Sensor – Provides ISD with tank ullage pressure for vapor containment leakage and overpressure monitoring
  • ISD Software Enhancement Feature – Unlocks the ISD software in the TLS console to provide continuous vapor recovery monitoring

Cost Effective Solution

The TLS-450PLUS console provides an expanded, advanced feature set at a lower price point than the TLS-350 console without needing to replace existing probes or sensors.

  • Continuous monitoring identifies failed vapor recovery equipment during warranty periods without expensive manual testing
  • ISD sensors can share wiring conduit with other Veeder-Root Intrinsically Safe (IS) sensors
  • Simple installation, compatible with all dispensers
  • Single dispenser or STP shutdown to maximize site uptime
  • Wireless option available

 

TLS-450PLUS Monitoring System Requirements

  • Universal Sensor Module (USM), Universal Input/Output Interface Module (UIOM), RS-232/485
  • Dispenser Interface Module (DIM)
  • ISD Software Enhancement
  • Site Shutdown Control Hardware
