  • Publication number: 20130085687
    Abstract: A method and a device for determining the flow rate of magnetic or ferromagnetic particles in a suspension that flows through control chambers are provided. The magnetic flux F1 is measured as a function of time t using a measuring coil that surrounds a first control chamber, the magnetic flux representing a measurement, at a particular time, of the quantity of magnetic particles contained in the suspension. In a second control chamber, at a predetermined distance d from the first control chamber, the magnetic flux F2 is measured as a function of time t using a second measuring coil that surrounds the second control chamber and the measurements F1 (t) and F2 (t) are compared to produce a temporal distance ?t which is used together with the predetermined distance d to calculate the flow rate. The method and device can be used, for example, in an ore mining installation.
