PURPOSE:To facilitate measuring operation by linking a measurement ring with a conduit and measuring the electric resistance of a multiphase flow between metallic rings, and calculating the amount of mixture of the multiphase flow from the relation between the amount of mixture and an electric resistance value calculated as to a multiphase flow whose mixture amount is already known. CONSTITUTION:A measuring device 1 consists of the measurement ring 4 constituted by linking three insulation rings 2 and two metallic rings 3 in series and an electric resistance measuring instrument 6 connected to the metallic rings 3through lead wires 5. Then, a two-phase flow obtained by mixing a material which has greatly different electric conductivity with electrically conductive liquid is run through the measurement ring 4 to measure the electric resistance between the metallic rings 3 and 3. Then, the two-phase flow whose mixture amount of a mixed material is already known is measured by the measuring device 1 to fine the mass to the mixture from a measured electric resistance value of the basis of the relation between the electric resistance value and mass of the mixture. |
