ABSTRACT:
A petroleum stream control system includes a valve receiving a petroleum stream which divides the petroleum stream into at least two petroleum substreams in accordance with the control signal. A sample stream is withdrawn from each substream and irradiated with microwave energy. 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 control circuit provides the control signal to the valve in accordance with the signals from the signal circuit, so as to control the dividing of the petroleum stream.
