Abstract: An apparatus includes a tube, first and second pairs of electrodes, a reference device, and a processor. The processor determines a speed of a fluid traveling between the first and second pairs of electrodes and determines a reference conductance of the fluid using the reference device. The processor also determines a measured conductance of the fluid using at least one of the first and second pairs of electrodes and determines, based on the reference conductance and the measured conductance, a cross-sectional area of the fluid at an electrode. The processor further adds a correction factor to the determined speed to produce a bulk speed of the fluid. The processor further determines a volumetric flow rate of the fluid based on the bulk speed and the determined area and determines a volume of the fluid based on the determined volumetric flow rate.
