A device for determining the volume when dispensing a carbonated drink, in particular beer from a supply tank to a restaurant tank, with • a transfer line (L; 14, 14a, 12, 10a, 10, 8) that serves to transfer the drink and extends from the supply tank to the restaurant tank, • a measuring line that forms a section of the transfer line, • a flow measuring apparatus assigned to the measuring line for measuring a quantity of drink flowing through the measuring line, • a gas extractor arranged upstream from the flow measuring apparatus for removing the gas components from the drink flowing in the measuring line, • a pump arranged upstream from the gas extractor in the measuring line, and a check valve/pressure retention valve arranged downstream from the flow measuring apparatus in the measuring line, characterized in that at least one of the following apparatuses (M; M1, M2, M3, M4) is arranged at least at one point in the transfer line, (a) an apparatus that is configured to measure the system pressure at the suction side of the pump and determine a pressure drop to the solution pressure of the carbon dioxide in the drink as a pressure measuring apparatus; (b) an apparatus that is configured to at least qualitatively or also quantitatively detect the gas bubbles contained in the flow at the suction port of the pump as a gas bubble recognition apparatus; (c) an apparatus that is configured to evaluate or interpret the measured information from the flow measuring apparatus as a flow monitoring apparatus for a critical reduction to be established, or a critical falling gradient of the flow in the measuring line; (d) an apparatus that is configured to ascertain the flow in the restaurant-tank-side end of the transfer line as an apparatus detecting the flow for a critical reduction to be established, or a critical falling gradient; (e) an apparatus that is configured to at least qualitatively or also quantitatively detect the gas bubbles contained in the flow in the restaurant-tank-side end of the transfer line as an apparatus detecting a liquid or gas bubbles; and that the apparatus (M1, M2, M3, M4) is furthermore configured to generate a control signal that quickly stops the pump in fractions of seconds upon the early recognition of a pending, or detection of a complete, release of carbon dioxide. • a transfer line (L; 14, 14a, 12, 10a, 10, 8) that serves to transfer the drink and extends from the supply tank to the restaurant tank, • a measuring line that forms a section of the transfer line, • a flow measuring apparatus assigned to the measuring line for measuring a quantity of drink flowing through the measuring line, • a gas extractor arranged upstream from the flow measuring apparatus for removing the gas components from the drink flowing in the measuring line, • a pump arranged upstream from the gas extractor in the measuring line, and a check valve/pressure retention valve arranged downstream from the flow measuring apparatus in the measuring line, (a) an apparatus that is configured to measure the system pressure at the suction side of the pump and determine a pressure drop to the solution pressure of the carbon dioxide in the drink as a pressure measuring apparatus; (b) an apparatus that is configured to at least qualitatively or also quantitatively detect the gas bubbles contained in the flow at the suction port of the pump as a gas bubble recognition apparatus; (c) an apparatus that is configured to evaluate or interpret the measured information from the flow measuring apparatus as a flow monitoring apparatus for a critical reduction to be established, or a critical falling gradient of the flow in the measuring line; (d) an apparatus that is configured to ascertain the flow in the restaurant-tank-side end of the transfer line as an apparatus detecting the flow for a critical reduction to be established, or a critical falling gradient; (e) an apparatus that is configured to at least qualitatively or also quantitatively detect the gas bubbles contained in the flow in the restaurant-tank-side end of the transfer line as an apparatus detecting a liquid or gas bubbles;
