Abstract

A method and a device for determining the velocity of a mass flow of powdered/granular bulk material in a conduit ( 1 ). Periodic disturbances are introduced into the mass flow that affect its electrical properties at at least one first point of the conduit ("point of disturbance") (SST). Using an electrode mechanism (ME 1 . . . ME 6 ) an electrical current is produced by the mass flow at at least one second measuring point situated downstream of the point of disturbance ("measuring point") (MST), and temporarily occurring changes of the current based on the disturbances introduced upstream are measured via an evaluation circuit (REV). The speed of the mass flow is determined from the time dependency between measured changes and introduced disturbance.
