Abstract

Techniques for measuring a density of a liquid within a fluid that includes both a liquid and a gas are described. A pressure of the fluid oscillates according to a time-varying function, which causes a density of the fluid also to oscillate according to the same time-varying function (235, 404). A resulting pressure signal (302) and density signal (304) are analyzed to extract at least a first and second pressure value (225, 245) and at least a first and second density value (205, 240), (410), where the first pressure and density values occur at a first time, and the second pressure and density values occur at a second time. Then, the liquid density is calculated from the first and second pressure and density values (250, 414). As a result, the liquid density may be calculated quickly and easily, with a minimum of effort on the part of an operator, and without requiring disruption of other measurement processes associate with the flowtube.
