A signal of the Karman vortex 17 from a filter amplifier circuit 30 is input to a bubble detector 61 through an A/D converter 60. A bubble mixture amount computing section 47 always monitors whether or not an amplitude value of the A/D converted vortex signal exceeds a threshold (a correspondence value of a bubble mixture amount to a vortex frequency is stored beforehand in a memory section 44 by each aperture of a flowrate pipe). When it exceeds the threshold, a flowrate computing section 46 outputs a value which is obtained by subtracting the bubble mixture amount from a whole flowrate. Only the bubble mixture amount can be displayed.  <P>COPYRIGHT: (C)2009,JPO&INPIT
