<p>PURPOSE:To correct delay in a high frequency response of a thermosensitive flowmeter lest a sharp change in the flow rate should be amplified excessively. CONSTITUTION:When the latest value of an output voltage Us of a thermosensitive flowmeter 1 is represented by QB2 and the previous output voltage Us by QB1, a correction value by I1 and the previous value of the correction value I1 by I0, the correction value I1 is calculated according to an expression of I1=(QB2-QB1+I0, XJ (wherein J is constant) at each sampling time of the output voltage Us. On the other hand, when a measured value of which response delay is corrected, is represented by QA, the corrected measured value QA is calculated according to the expression QA=(QB1-I1)+(QB2-QB1+I1)XK (wherein K is constant) at each sampling time.</p> |
