ABSTRACT:
Apparatus monitors the water cut of a petroleum stream flowing in a pipeline by comparing a probe signal to a reference signal. A probe is located in the pipeline and is connected to the reference signal through a series resistance. The probe signal changes as a function of the impedance of the petroleum stream. A circuit measures the changes in the probe signal, compares the changes to the reference signal and derives a water cut value for the petroleum stream based on these measurements.
