  • Dual differential pressure multiphase flow meter
    Patent number: 8973433
    Abstract: A flow meter and method of determining a parameter of a downhole multiphase fluid is disclosed. Multiphase fluid flows through a downhole tubular member having first section, second section and third section, wherein the second section is disposed between the first section and the third section and an inner diameter of the second section is greater than an inner diameter of the first section and an inner diameter of the third section. Absolute pressure measurements of the multiphase fluid are obtained at each of the first section, second section and third section using absolute pressure gauges. The parameter of the downhole multiphase fluid is determined from the absolute pressure measurements.
