Abstract: Method for measuring a variation in pressure or in volume in a reservoir (10) containing a liquid and connected via a passage (18) to a measuring column (20) partially filled with liquid. The method uses a means for lighting (24) and a means (22) for image taking in order to detect the first peaks of the oscillations of the level of liquid in the column (20) caused by a variation in pressure or in volume in the reservoir (10). A solenoid valve arrangement is placed in the passage between the reservoir and column for controlling the flow of liquid between them. In an alternative embodiment the liquid level may be measured via CCD camera, photo-electric, capacitive or ultra-sonic level sensors.
