Abstract
Method and apparatus for inductive flow measurement using a periodically reversed magnetic field, in which the useful signal is obtained by sampling and storing the signal voltage at equal but opposite values of induction of magnetic field and forming the difference of the stored sample values. There is formed between each two successive magnetic field impulses of opposite polarity an interval where the magnetic field is zero, there being generated in a compensation time interval within each magnetic field interval at the same time-interval before the next subsequent sampling of the signal voltage, a compensation voltage which restores the signal voltage during the compensation time interval to zero value. The compensation voltage value developed during the compensation time interval is stored and is employed until the next compensation time interval.
