METHOD AND DEVICE FOR MEASURING A GAS-SOLID OR LIQUID-SOLID DIPHASIC FLOW RATE

摘要

P Method for determining the mass flow rate of a pulverulent or granular solid product in a fluid current handling installation, characterized in that the total pressure drop Pt existing between two sections 13 is measured, 14 distant from the distance L in an ascending vertical pipe transporting the fluid loaded with the pulverulent mixture, which is also determined or calculated as the pressure drop Pg due to the fluid alone between these same sections, of diameter D and of section S, then that as a function of the constant g of the acceleration of gravity of the coefficient of friction fs of the particles and the average speed of the solid particles Us determined by intercorrelation, the mass flow rate of solid particles Ms is calculated . /P
