Abstract
A flow metering method for an annular gas and liquid flow comprises the following steps of: first, enabling a gas and liquid mixed fluid to flow through a vertically arranged circular pipe so as to form the annular gas and liquid flow; and then measuring total flow or liquid average velocity or gas average velocity of the gas and liquid mixed fluid; measuring physical quantities, such as temperature, pressure, gas fraction and the like, of the gas and liquid mixed fluid; and finally, accurately figuring out liquid volume flow and gas volume flow according to analysis of a gas and liquid slip factor.
