Abstract
Method for operating for measuring the flow velocity of a flowing medium using a measuring device in which a magnetic field is induced in the flowing medium and on which a interference voltage is superimposed. During compensation measuring, a first magnetic flux density is generated in the medium and a first measuring voltage determined, a second magnetic flux density is generated in the medium and a second measured voltage determined, and a third magnetic flux density is generated in the medium and a third measured voltage determined. The flow velocity is determined from the first and second magnetic flux densities and measured voltages, and the interference voltage is determined form the third magnetic flux density and measured voltage and the determined flow velocity. Then, a fourth measured voltage is determined, and the flow velocity re-determined from the third magnetic flux density, the fourth measured voltage and the determined interference voltage.
