Abstract: PURPOSE:To reduce effect of an external vibration or the like, by integrating a difference signal between one and the other detection signals by an output signal of a wind comparator when one detection signal is between two thresholds. CONSTITUTION:A wind comparator 35, which is supplied with a detection signal e1 at an input terminal (d), generates a square wave signal e4 which goes to an H level when the detection signal e1 is above a negative threshold and below a positive threshold. A subtraction circuit 36 subtracts the detection signal e1 from a detection signal e2 to form a difference signal e3, which is supplied to an integration circuit 37. The integration circuit 37 integrates the difference signal e3 while the signal e4 is at the H level to form an integration signal e5 and, moreover, a peak holding circuit 40 holds the max. value of the integration signal e5 to output a max. value signal e6. Then, an amplitude control circuit 42 controls the amplitude of vibration of sensor tubes 13 and 14 so as to keep the max. value of the detection e2 constant.
