Abstract:
1. An apparatus configured to determine fractions of various phases in a multiphase fluid, comprising: a main body including an interior configured to receive a multiphase fluid and an exterior; a pressure sensor configured to sense a fluid pressure of multiphase fluid received in the interior; a temperature sensor configured to sense a fluid temperature of the multiphase fluid; at least one ultrasonic transducer and sensor pair configured to transmit and detect an ultrasonic wave in the multiphase fluid; and a computer configured to determine a gas fraction, water fraction, and a non-water fluid fraction of the multiphase fluid based on the sensed fluid pressure, the sensed fluid temperature, and at least one characteristic of the ultrasonic wave in the multiphase fluid detected by each of the at least one ultrasonic transducer and sensor pair.
