Abstract

PURPOSE:To obtain the correct or approximately accurate concentration signals of suspension comparatively continuous, by judging the deviation value of concentration signals after bubbles are broken and when bubbles are not broken yet, and by automatically correcting the value as necessary. CONSTITUTION:A concentration detector 11 with an antifrothing device takes in one portion of suspension, breaks bubbles by antifrothing instruction signals from a sequence circuit 17, and supplies concentration observation to a signal output circuit 14. A concentration detector 10 feeds concentration signals in the case when the bubbles are not broken yet, which are successively supplied, to a signal output circuit 15. Whether or not the deviation value of concentration signals after the bubbles are broken and when the bubbles are not broken yet is within allowance beforehand decided is inspected by applying the output of the two circuits 14, 15 to a decision circuit 16, and the concentration signals in the case when the bubbles are not broken yet are put out if the value is within the allowance.
