Abstract
A vapor recovery system for use in a fuel dispenser. The system has a vapor recovery line for collecting fuel vapor. A Fleisch tube is mounted in the recovery line and connected to a differential pressure transducer for monitoring the volumetric flow rate of fuel vapor through the recovery line. The Fleisch tube provides highly accurate flow rate measurements which are used to set the appropriate vapor recovery rate.
