Abstract: In this inductive flow meter a pair of electrodes are disposed on opposite sides of a tube through which flows the fluid being measured. A magnetic field is generated across the tube, the strength of which increases and decreases linearly with time. The voltage developed across the electrodes is scanned by first and second sample and hold circuits operative respectively near the beginning and near the end of each increasing or each decreasing branch of the magnetic field cycle. A difference circuit obtains the mean value of the difference between the sampled voltages; this value very accurately indicates the flow rate, since the described circuitry compensates for various system error voltages.
