Ultrasonic signal travel time determination procedure measures phase difference using quadrature demodulation for partial inversion with clock and phase shifted clock signal |
摘要 |
<p>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.</p> |
