ABSTRACT:
A procedure for the determination of the true average peak velocity of particulate laden liquids in a tube, by the use of a Doppler ultrasonic transducer inserted in said tube. The average peak velocity (APV) and the null and first moment (M0 or M1) of the entire spectrum are obtained. The measured correlation between the null or first moment (M0 or M1) and APV are compared with a corresponding standard value which represents the correlation between M0 or M1 and APV upon optimal positioning of the Doppler ultrasonic transducer whereby where there is a deviation from the standard value, the transducer is moved until the values coincide.
