Abstract: Systems and methods can be used for correcting for the presence of voids in a fluid when measuring the conductivity thereof. The conductivity of a fluid can be measured using a conductivity sensor. Capacitance electrodes can be used to measure the capacitance of the fluid. The measured capacitance affected by the fluid can be used in combination with the measured conductivity to determine a corrected conductivity value that compensates for possible voids in the fluid. Other parameters, such as the makeup or temperature of the fluid can be used in determining the corrected conductivity measurement. Some such systems include an annular housing and can be inserted or integrated into fluid flow systems so that fluid to be analyzed flows through an aperture defined by the annular housing.
