Title:
モジュロ2pi剰余トラッキングを用いた超音波流量センサ
Document Type and Number:
Japanese Patent JP4904289
Kind Code:
B2
Abstract:
An ultrasonic signal travel time determination procedure measures the phase difference using quadrature demodulation for partial inversion of the received signal using a clock (8) and phase shifted clock (9) and integration with the remainder determined from signal characteristics. Independent claims are included for ultrasonic flow rate sensors using the procedure.
