Method and device for measuring a two-phase flow of gas - solid or liquid, solid -

摘要

Process for the determination of the flow rate - mass of a solid product in powder or granular form in an installation for handling by a flow of fluid, characterized by the fact that the measurement is the loss of the total pressure pt between two sections 13, 14 at a distance of the distance l in an ascending vertical pipe conveying the fluid loaded with the pulverulent mixture, that is determined, or which is calculated by the loss of charge and pg, due to the fluid only between these same cross section, of diameter d and of section s, then as a function of the constant g of the acceleration of gravity of the coefficient of friction f of the particles and the average speed of the solid particles, u.s. pat. no. determined by interpolation, it calculates the flow rate - mass of solid particles (ms).
