ABSTRACT:
A liquid level indicator comprises an elongate member extending vertically through a liquid container, the weight of the member being sensed as a measure of the liquid level in the container. At least at one predetermined point of its length, the member is formed with a transverse portion having a lower surface extending substantially horizontally. Furthermore, the member is tubular, and the transverse portion is located within the tube but does not occupy the entire internal cross-sectional area thereof. To determine the absolute position of the liquid level, the indicator utilizes an instantaneous change of weight provided by the liquid.
