ABSTRACT:
There is disclosed an apparatus of the bubble type for accurately measuring the quantity of liquid in a tank. The apparatus functions by supplying an accurately measured quantity of purge gas at an accurately controlled predetermined pressure and flow rate through a selector valve to a tube extending to the bottom of any one of a number of liquid-containing tanks to be monitored. When the apparatus is actuated, purge gas first clears the tube of substantially all liquid originally disposed therein and then stabilizes at a pressure which accurately reflects the liquid depth in the tank. A method of making such measurements is also disclosed.
