ABSTRACT:
A multiphase petroleum stream monitoring system and method includes withdrawing a first sample stream from the petroleum stream. Both sample streams are irradiated with microwave energy. A second sample stream is withdrawn from the petroleum stream. Microwave energies that have passed through the sample streams are received. A signal circuit generated signals corresponding to an electrical property of the sample stream in accordance with the received microwave energies. A computer determines the validity of the sample streams and provides a water cut data on the petroleum stream when sample streams are valid sample streams.
