Abstract
A distributed flow properties wellbore measurement system. In a described embodiment, a system for determining at least one parameter of a fluid in a tubular string includes a pressure pulse generator attached to the tubular string and a set of sensors. The generator transmits a pressure pulse through the fluid. The set of sensors is used to determine a velocity of the pressure pulse transmitted through the fluid, and to determine a velocity of the pressure pulse reflected back through the fluid.
