The Veeder-Root In-Station Diagnostics (ISD) solution is a comprehensive product designed to monitor gasoline dispensing facilities according the standards defined by the California Air Resources Board (CARB) Phase II Enhanced Vapor Recovery (EVR) Executive Orders (EO).
The Veeder-Root CARB-certified ISD system provides the most accurate vapor-recovery detection available in the industry and is the choice of over 90% of the sites that need to meet the California Enhanced Vapor Recovery regulations. The vapor flow meter measures the amount of gasoline vapor returning from the car while the pressure sensor monitors your tank 24 hours a day to ensure proper functioning of your vapor-recovery system. It also monitors the vapor space integrity of the underground storage tanks as well as the vapor piping.
