Abstract

Mathematical models of magnetic circuits of electromagnetic flow transducers with an annular channel have been developed, taking into account the distribution of the parameters of the magnetic circuit and leakage fluxes closed through non-working air gaps. The possibility of compensating for the difference in magnetic resistance of coaxially arranged concentric ferromagnetic cores due to the difference in their circumference by selecting the thickness of the cores is shown. It is established that the magnetic flux in concentric ferromagnetic cores is nonlinearly distributed along the angular coordinate, and the magnetic induction in the annular channel is unevenly distributed along the angular and radial coordinates. It is revealed that with an increase in the value of the magnetic field attenuation coefficient in the magnetic circuit, the degree of non-uniformity of the magnetic induction in the annular channel with respect to the angular coordinate increases, and with respect to the radial coordinate it remains constant.
