Abstract
The invention relates to a device for online measurement of gas flowrate and liquid flowrate of a wet gas in a horizontal pipe, comprising the following parts: a horizontal Venturi tube, comprising a truncated cone-shaped inlet pipesection with section area reduced gradually, a cylindrical throat pipesection and a truncated cone-shaped outlet pipesection with section area increased gradually; and a gamma ray monitor, comprising a gamma ray emitter and a gamma ray detector arranged in a manner that gamma rays emitted by the gamma ray emitter can radially pass through the cross section of the throat pipesection to reach the gamma ray detector. The invention also relates to a method for online measurement of gas flowrate and liquid flowrate of a wet gas in a horizontal pipe by using above device.
