Title:
POSITIVE DISPLACEMENT GAS-LIQUID TWO-PHASE FLOWMETER AND MULTIPHASE FLOW RATE MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/027606
Kind Code:
A1
Abstract:
Provided is a positive displacement gas-liquid two-phase flowmeter for, when measuring the respective flow rates of a gas-liquid two-phase flow comprising liquid and gas, accurately measuring the flow rates in a wide flow rate range by a compact and robust structure that is less susceptible to the flow pattern. A positive displacement gas-liquid two-phase flowmeter (10) measures the total gas-liquid flow rate (QM) of a gas-liquid two-phase flow comprising liquid and gas, and the ratio (gas void fraction (β)) of the gas flow rate to the total gas-liquid flow rate, and calculates the respective flow rates of the liquid and the gas on the basis of the total gas-liquid flow rate (QM) and gas void fraction (β). The positive displacement gas-liquid two-phase flowmeter (10) is provided with a positive displacement flow rate measurement chamber (16) for measuring the total gas-liquid flow rate (QM) and provided with a gas-liquid mixing chamber (14) for mixing the liquid and the gas in the gas-liquid two phase flow at a stage preceding the positive displacement flow rate measurement chamber (16).
