METHOD FOR MEASURING CONSTITUTION RATE OF MULTI-PHASE FLUID AND CONSTITUENT RATE METER UTILIZING THE SAME

摘要

PROBLEM TO BE SOLVED: To more accurately measure the constituent of each fluid for composing a polyphase fluid. SOLUTION: In a method for calculating the constituent rate of each fluid for composing a multi-phase fluid by measuring specific physical characteristics regarding the multi-phase fluid consisting of liquid that is made of water and oil flowing in piping and gas, an average relative dielectric constant of the multi-phase fluid that is obtained from the specific physical characteristics being measured at the moment when the piping is filled with water and oil is calculated by a function for expressing a calibration curve 61 of the average relative dielectric constant, and the average relative dielectric constant of the multi-phase fluid obtained from the average value of the measured physical characteristics is calculated by a function for expressing a calibration curve 65 of the average relative dielectric constant for connecting a value 63 that is determined from the physical characteristics of the liquid consisting of water and oil and a value 64 that is determined from the physical characteristics of gas.
