Abstract

PURPOSE: To discriminate the effectiveness or ineffectiveness of data simultaneously with its processing, by comparing an actual data sampling interval with a previously set ideal sampling interval.
CONSTITUTION: A Doppler flow meter 1 acts to measure the flowing velocity of air by utilizing the Doppler effect. A Doppler signal is applied from the flow meter 1 to a signal processor 2 to determine the flowing velocity of air on the basis of the frequency of the Doppler signal. The output signal of the signal processor 2 is stored in a wave form memory 3. When the signal processor 2 generates a pulse, a counter 8 in an effectiveness or in-effectiveness discriminator 4 loads a pulse interval allowable value from a reference time setting unit 5 and counts down pulses from an oscillator 6. When the counted value becomes zero, the counter 8 produces a borrow signal and supplies it to an up-counter 10. A signal showing a measurement section is applied as a reset signal to the counter 10. A comparator 12 compares a counted value k1 within the measurement section with an allowable value k0 set by an allowably value setting unit 11. When the counted value k1 exceeds the allowable value k0, sent data are regarded as improper.
