Title: Average-period computing device of output pulse from karman vortex type airflow-rate sensor
Inventor: TAKAHASHI MINORU
IPC: G01F1/32
Filed: 1984-05-23
Abstract: PURPOSE:To enhance the computing accuracy of an average period at the time of a large flow rate and to improve response at the time of small flow rate, by obtaining the average of the output pulses of a Karman sensor at an every plurality times of changes at the time of the large flow rate, and obtaining the average period at every number of pulses corresponding to the second specified value at the time of the small flow rate. CONSTITUTION:The first specified time (a), which is relatively shorter than the maximum period and appears at the time of a large flow rate, is provided. The period of a pulse signal is compared with the specified time by a pulse-period comparing means 4. The breakpoint of the change at the time of the large flow rate is detected. When the breakpoints of changes are detected by the times corresponding to the third specified value (b) by an average computing means 2, the average is obtained. Thus the average at every plurality of changes at the time of the large flow rate can be computed. The period of the output pulses (d) of a Karman sensor at the time of a small flow rate is longer than the first specified time (a). Therefore, the average is obtained at every time when the result of comparison of the comparing means 4 becomes larger by the times corresponding to the second specified value (c). Thus the averaging of the periods for every pulses corresponding to the second specified value can be conducted.
