Abstract
Электромагнитный способ измерения расхода Qm сухой металлосодержащей массы ферромагнитной пульпы, протекающей через немагнитную трубу, с изоляционным покрытием канала и двумя электродами, на поверхности которой расположены измерительная и намагничивающая катушки, имеющие общую ось, перпендикулярную оси канала и осям электродов, магнитопроводом, охватывающим трубу с катушками, предусматривающий при пропускании тока I через намагничивающую катушку измерение разности потенциалов между электродами Uэ и напряжения U, возбуждаемого в измерительной катушке, отличающийся тем, что расход сухой металлосодержащей массы пульпы вычисляется по формуле ! , ! где ρ - плотность сухой металлосодержащей массы, α, k - градуировочные коэффициенты, D - диаметр канала трубы, µ - магнитная проницаемость сухой металлосодержащей массы.An electromagnetic method for measuring the flow rate Qm of dry metal-containing mass of a ferromagnetic pulp flowing through a non-magnetic pipe with an insulating coating of the channel and two electrodes, on the surface of which there are measuring and magnetizing coils having a common axis perpendicular to the axis of the channel and the axes of the electrodes, with a magnetic circuit covering the pipe with coils involving the passage of current I through a magnetizing coil, the measurement of the potential difference between the electrodes Ue and the voltage U excited in a coil, characterized in that the flow rate of the dry metal-containing pulp mass is calculated by the formula! ! where ρ is the density of the dry metal-containing mass, α, k are the calibration coefficients, D is the diameter of the pipe channel, and μ is the magnetic permeability of the dry metal-containing mass.
