摘要： Several embodiments include a method of computing void fraction in a two-phase mixture in a pipe. A driver and a transmitter antenna can transmit a radio frequency (RF) signal through the pipe. The pipe can convey the two-phase mixture extracted from a geothermal well. The RF signal can pass through the two-phase mixture. A receiver antenna in the pipe can receive the RF signal. A receiver circuit can measure signal strength attenuations of the RF signal at the receiver antenna over a time window. A computation engine can compute an average of the signal strength attenuations over the time window. The computation engine or another computing device can then compute, in real-time, a change in a void fraction of the two-phase mixture based on the average of the signal strength attenuations.

摘要： Several embodiments include a method of computing a phase composition ratio of a two-phase mixture in a pipe. For example, the phase composition ratio is a void fraction or a dryness fraction. The two-phase mixture can have one or more material substances that do not travel as a whole (e.g., at least two of solid phase, liquid phase, and gaseous phase or two liquid materials of different densities that do not mix). A load cell can measure, continuously, weight of the pipe and content of the pipe. Then, a computing system or a circuit can compute, continuously, a moving average of the continuously measured weight. The computing system or the circuit can compute a change in the phase composition ratio of the two-phase mixture based on the computed moving average.
