Abstract
An ultrasonic transducer apparatus of variable frequency including a diffracting structure adapted for emitting and receiving a plurality of diffracted ultrasonic beams of calculable different angles for determining the velocity of a fluid flowing through a lumen, and flow volume. Velocity and flow volume are determined from at least two equations in the two unknowns of the velocity, and the angle between the ultrasonic transducer apparatus and the direction of the fluid flow, and from a determination of the diameter of the lumen.
