摘要： Both a flow meter system and method are provided for accurately measuring the percentage amounts of liquid and gas phases in a multiphase flow through a conduit when the liquid phase constitutes a small minority portion (e.g., less than about 20%) of the multiphase flow. The system includes a flow meter that includes a differential pressure sensor connected across a Venturi in the conduit, and a dual energy fraction meter, each of which is operably connected to a digital processor. The system further includes a pump connected to the conduit upstream of the flow meter that introduces at least one pulse of a known quantity of liquid, the pulse being sufficient in volume to temporarily increase the liquid phase by a detectable amount. After the liquid pulse is introduced into the multi-phase flow, the digital processor computes the changes in the percentage amounts of the liquid and gas phases which should have occurred as a result of the pulse, and compares the computed changes with the actual changes measured by the flow meter in order to calibrate the flow meter. The measured increase in the liquid flow is then subtracted from the total measured liquid flow to determine the actual percentage of liquid flow.

摘要： A flow meter apparatus and method are presented for measuring a flow rate of a multiphase fluid mixture comprising at least one gas phase and one liquid phase. The flow meter comprises a pipe section and measurement section through which the mixture flows. The flow meter also comprises a fraction measurement device adapted to estimate a representative fraction of the gas phase and/or liquid phase of the mixture passing at the measurement section. Moreover, the flow meter preferably comprises at least one ultrasonic sensor arranged to estimate a characteristic, such as liquid film thickness or velocity, of a portion of the liquid phase flowing as liquid film along a wall of the pipe section. The characteristic is preferably used to correct the estimated representative fraction of the gas phase and/or liquid phase when the gas phase flows in a core of the pipe section, and a portion of the liquid phase flows partially as liquid film along the wall of the pipe section and another portion of the liquid phase flows partially as liquid droplets in the core of the pipe section.
