System for measuring the efficiency of hydrocarbon vapor recovery installations used in gas stations |
摘要 |
The efficiency of hydrocarbon vapor recovery installations used in gas stations is measured. A system for measuring a yield of recovery for hydrocarbon vapors emitted from the tank of a vehicle as it is being filled comprises at least one box for carrying a nozzle inside and for placement over a filler neck of the tank. The nozzle is connected through a conduit to a device for evaluating the recovered hydrocarbon vapor, wherein the recovered vapor evaluation device is a gas meter and a following orifice.
