Abstract
Four ultrasonic methods are described for the measurement of volumetric flow without using angle correction. The geometrical configurations are spherical, cylindrical, fan and plane scanning. The cylindrical and fan methods are two new innovations. Flow measurement is achieved by numerically integrating the product of velocity and surface area. The flow of interest should be inside the boundary of the surface of integration. Each small area on the surface is chosen to be perpendicular to the direction of the ultrasonic beam. In this way, 3-dimensional (3-D) flow can be measured even though ultrasound Doppler only provides 1-D velocity information. The four methods described offer the possibility of 3-D measurement of flow and allow the use of several different types of ultrasonic transducers.
