Abstract

PURPOSE: To eliminate noise arising by an exciting current by sampling output signals of a pair of electrodes crossed with an axis of a pipe in which a fluid to measure flows at a neutral point of a noise wave form of the exciting current.
CONSTITUTION: An oscillator 1 consists of a pair of electrodes 4, 4 provided in the direction crossed with an axis of a pipe 3 in which a fluid to measure flows and exciting coils 5, 5 forming a magnetic field crossed with the electrodes 4, 4 by an exciting power circuit 6, and a voltage signal proportional to a velocity of the fluid flowing in the pipe 3 is obtainable from the electrodes 4, 4 by excitation of the exciting coils 5, 5. Then, a timing signal generating circuit 22 is constituted so that points t0, t1, t2 whereat a noise according to an exciting current indicated by A in the illustration comes to zero cross are included by allowing outputs of the electrodes 4, 4 to pass a high-pass filter 12, and the noise according to the exicitng current can thus be eliminated through sampling 17.
