A liquid flow measuring system which, by means of a suitable timing sequence, is able to detect unbalanced voltage generation which occurs when the tube element through which the liquid is flowing is not completely full and, by means of a correction process, supplies an output signal which is proportional to the rate of flow. When the tube element is full, the system operates in the same way as a normal magnetically inductive flowmeter. If the level in the tube element falls, electrodes which are installed in the lower half of the tube element and other electrodes, if necessary, can be used exclusively or additionally to record the measured values. Moreover, with a view to improving the recording of measured values when the level falls below a specific limit, an arrangement of electromagnets, specially optimized for partially filled tube elements, can be activated instead of the normal arrangement of electromagnets.
