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.

Level measuring bubbler tube tip

A tank leak detection system in which a liquid level multiplier is connected to a differential pressure transmitter one side of which may be piped back into the tank to compensate for internal changes in tank pressure. A capillary having a small bore connects the transmitter and the multiplier to reduce temperature effects. Changes in tank temperature may be sensed, i.e., by a long bulb thermometer and either fed to a temperature transmitter to convert temperature change into a single to a computer used to calculate true tank level and output a signal proportional thereto or fed to the level transmitter to compensate for temperature changes.
