Abstract
An apparatus for determining fluid flow in a pipe apparatus includes a fluid nozzle in contact with the pipe having a contour without negative pressure gradients along the nozzle's surface as fluid flows through the nozzle. The apparatus includes a transit time ultrasonic flow meter employing at least one acoustic path in communication with the fluid in the pipe and disposed downstream of the nozzle. An apparatus for determining fluid flow in a pipe. The apparatus includes a fluid nozzle in contact with the pipe having a contour defined by a compound cubic. The present invention includes a transit time ultrasonic flow meter employing at least one acoustic path in communication with the fluid in the pipe and disposed downstream of the nozzle. A fluid nozzle for a pipe. A method for determining fluid flow in a pipe.
