A watercut monitor device has an oscillator circuit which generates an analog input signal in response to the capacitance of a capacitance probe through which an oil and water emulsion flows. The frequency of the analog input signal is non-linearly related to the watercut of the emulsion. The analog input signal is effectively gated through a digital gating circuit, and a count related to the frequency of the gated signal is digitally made. The digital count addresses a digital memory having digital values, which are linearly related to the watercut of the emulsion, stored therein. Upon being addressed, the digital memory outputs the digital value stored in the addressed location. The digital value is optically coupled to a digital-to-analog converter which converts the digital value into an analog output signal linearly related to the watercut of the emulsion.

Watercut monitor device and method

A microprocessor controlled apparatus monitors a plurality of flow meters for computing and displaying the flow rates detected by each flow meter, the total volumes accumulated through each flow meter, the sum of the current flow rates for the flow meters, and the sum of the total volumes for the flow meters. The information from which the computations are made and the system operating parameters are transferred to a non-volatile memory in response to electronic means for detecting when a power outage or interruption occurs.
