| Abstract: | A new type of gas-liquid two-phase flow meter-T-junction ESM (Extracting and Separat- ing Method) two-phase flow meter is proposed and tested in this paper. By utilizing the phase split phenomena in T-junctions, a single-phase gas stream is extracted, through branch legs of T-junctions, from the gas-liquid two-phase flow to be measured, and its flow rate is metered with a conventional single phase flow meter. The measured value of extracted gas flow rate was, then, being used to calculate the mass flow rate or mass quality of two-phase mixture to be measured according to the extraction ratio. The characteristic of extraction ratio was also investigated theoretically and experimentally in this paper. |
