VAPOR RECOVERY SYSTEM WITH INTEGRATED MONITORING UNIT

摘要

A vapor recovery system (20) with integrated monitoring unit (28). The system includes one or more tanks (22, 24, 26) into which captured vapor is returned. A pressure sensor (52) is mounted into each tank not in fluid communication with the other tanks. The signals produced by the pressure sensors are forwarded to a control module (54). In the event the measured pressure drops below a selected level the control module actuates an alarm (56). The control module also disables the dispenser (31, 32) generating the liquid that is being vaporized.
