Conductivity sensor with void correction

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. 本发明公开可用于在测量流体的导电率时校正所述流体中空隙的存在的系统和方法。可以使用导电率传感器测量流体的所述导电率。电容电极可用于测量所述流体的电容。受所述流体影响的所测量到的电容可与所测量到的导电率结合使用，以确定补偿所述流体中可能的空隙的经校正的导电率值。其它参数，例如所述流体的组成或温度可用于确定经校正的导电率测量值。些此类系统包含环形壳体并且可以插入或集成到流体流动系统中，使得待分析的流体流过由所述环形壳体限定的孔。
