In-station Diagnostics

In-station diagnostics (ISD) ensures that all components of the vapor recovery system are functioning normally.

Pair ISD hardware with a TS-EMS, TS-550, or TS-5000 with vapor recovery monitoring software for a full ISD solution.

Vapor Recovery Monitoring Software

The vapor recovery monitoring (VRM) software meets or exceeds all California Air Resources Board (CARB) ISD requirements. VRM software gauges the effectiveness of a station’s vapor recovery equipment through continuous monitoring of gasoline vapors during fueling operations.

Vapor Flow Meters

Recorded sales transactions are compared to data obtained from a TS-VFM vapor flow meter installed in each dispenser to verify that equivalent vapors are recovered from the vehicle when fuel is dispensed.

Vapor Pressure Sensors

The pressure of the vapor containment space is constantly monitored by the TS-VPS vapor pressure sensor and tested for over pressure and leakage conditions. Local and remote notification options alert the user of abnormalities and dispenser-based disabling keeps the rest of the site up and running when a single dispenser EVR system has a problem.

More Features

  • Dispenser-based disabling prevents the entire site from shutting down in the event of an EVR failure.

  • Ethernet-ready, web-based remote access provides the user with remote access to VRM status information, reports and alarm information using any web browser.

  • Create custom rules to send e-mails and text messages on alarms and events directly from the console to service and compliance personnel.

  • User-friendly touch screen interface with icon-based navigation.

  • Scalable open architecture for easy and cost-saving future upgrades.
