Abstract
An apparatus for adjusting the level of a liquid filling a packaging tube comprises a float for use as suspended in the liquid filling the tube, a magnet attached to the float, and a magnetic sensor for detecting from outside the tube variations in the intensity of magnetism due to the upward or downward movement of the magnet to produce an output signal. The level of the liquid in the tube is adjusted in accordance with the output signal of the sensor.
