ABSTRACT:
A level measuring system for measuring the level of a fluid in a tank employing tubes through which gas is passed extending to different levels in the fluid, whereby the level may be measured by comparing the differences in pressure necessary to release bubbles from the tubes. The ends of each of the tubes are bent at substantially a right angle, with the tips cut off at an angle so that the gas/liquid interface of the bubbles are at a more constant depth, and the bubbles are prevented from sagging.
