Abstract
A dispensing installation for fuel or other volatile liquids comprises a storage tank, a pipe and a pump for dispensing fuel, a vapor recovery pipe and pump for recovering vapor and delivering it back to the tank, and a controller maintaining the vapor delivery rate approximately equal to the liquid delivery rate. In order to check that the vapor recovery system is operating correctly, the vapor delivery rate is constantly detected and compared with a value of the liquid delivery rate. If the result of the comparison is outside a predetermined range, an alarm is triggered in order to indicate a malfunction. The predetermined range may be adjustable.
