To monitor the fermentation, within a fermentation tank for alcohol, the vapor from the fermentation tank is measured for volume and temperature to determine the fermenting condition. The tank (A) has a pipe (15) at the upper side with a flow meter (16) opening into a bung (1) with a double-cylindrical body (2) and a cover (8). A further meter is between them forming a flow measurement unit (18). A filling level monitor (30) is at the side of the tank, with a transparent tube (31) charged at the bottom by a three-way valve (32) and a fluid level sensor (33) at the required filling height, preferably two-thirds of the capacity to prevent over-foaming. The flow rate and temperature are transmitted by radio to a data processing station. |
