Abstract
A device and method provide improved measurement of flow through an enclosed channel, such as a pipe. A flow measurement device, such as a differential pressure sensing pitot tube, includes a pressure sensing probe that is inserted into the pipe for measuring the rate of fluid flow therein. A compressible or elastic barrier is attached to the distal end of the sensing probe to fill the space between the tip end of the sensing probe and the nearby portion of the inside wall of the fluid carrying pipe. The resilient barrier prevents undesirable fluid flow between the tip end of the sensing probe and the inside wall of the pipe.
