METHOD FOR CONTROLLING THE OPERATION OF RECOVERY STEAM ISSUED IN SYSTEM INSTALLATION AND FUEL DISTRIBUTION that Installation FOR THE IMPLEMENTATION OF THIS METHOD.

摘要

Method for monitoring the proper functioning of the vapor recovery system transmitted in a fuel dispensing installation, said installation comprising: a storage tank, a liquid distribution conduit with a QL liquid flow, a vapor recovery line (16) with a vapor flow QV, adjusting means for maintaining the flow rate QV of vapor approximately equal to the liquid flow rate QL, characterized in that: constantly detects the QV value of flow by means of detecting (21), transmitting the vapor flow QV value thus detected to the comparator means (22) which compares a value of the liquid flow rate QL, and when the result of this comparison is outside of a predetermined range, if necessary adjustable, it triggers an alarm indicating a malfunction.
