Abstract
A ventilation-mast monitoring system for filling stations contains a thermal through-flow measuring device () and a hydrocarbon-measuring device (). The thermal through-flow-measuring device () has a heating device and a temperature sensor which is located in the flow path and reacts to the temperature of the heating device, and is configured to sense the gas volume flow escaping from a reservoir tank () via a ventilation mast () of the reservoir tank () of a filling station or entering the reservoir tank (). The hydrocarbon-measuring device () is configured to sense the direction of the gas volume flow escaping from or entering the reservoir tank () via the ventilation mast (). A control device which is configured to receive and to process measuring signals emitted by measuring devices of the system is preferably provided as a further system component.
