ABSTRACT:
A measurement system for the measurement of the velocity of liquid flow through a pipe wherein side-by-side ultrasonic transmitting and receiving transducers are positioned on a below liquid level area of the pipe and are oriented to transmit and receive, respectively, signals along essentially parallel paths which are essentially normal to the flow of fluid through the pipe. Modulation on a received signal is demodulated and the frequency of major signal excursions of the modulation are detected and employed as an indication of velocity of flow.
