Detecting trace amount of water in crude oil with capacitance sensors

A capacitive sensing system for trace amount of water content in crude oil is proposed. The capacitance sensor comprises a pair of copper electrodes wrapped around a tube with a 12mm diameter. The interface circuit is based on capacitance to phase angle conversion. A combination of differential sens...
