ABSTRACT:
An accurate measurement of liquid levels in a tank are made using a dual tube sonic level gage. This uses plane waves of sound, in air, propagated in two vertical tubular wave guides to locate the levels of liquid contained in each tube. One tube has slots at the bottom and allows both the light (upper) and the heavy (lower) liquids to be present inside the tube at the same level as outside (i.e. in the tank). The other tube allows only the lower liquid to enter it. In the application for a measurement of gasoline and water levels in a tank, levels outside the tube (i.e. in the tank) are calculated using the equations of hydrostatics. Corrections due to temperature need not be made in order to obtain levels accurate to 1 percent.
