摘要
In a process for the determination of the mass flow rate of a pulverulent or granular solid product in an installation for handling by fluid current, a measurement is made of the total loss of charge Pt existing between two pressure sensors 13, 14 spaced by the distance L within an ascending vertical duct transporting the fluid charged with the pulverulent mixture. A determination or a calculation is moreover made of the loss of charge Pg due to the fluid alone between these same sections, of diameter D and of cross-section S. As a function of the constant g of the acceleration due to gravity, of the coefficient of friction fs of the particles and of the average speed of the solid particles Us determined by intercorrelation using capacitive sensors 10, 11, a calculation is made of the mass flow rate of solid particles Ms. IMAGE
