Arrangement for measuring the speed profile of a fluid flowing in a pipeline

摘要

the arrangement has a housing (1) introduced into the pipeline as a pipe section in a fluid tight manner. An inner tube (5) rotatably mounted inside the housing has essentially the same dia. as the pipeline and is coaxial with it. A guide (12) connected to the inner tube is inclined wrt. The pipeline axis. A carriage (13) can move radially on the guide. A probe (18) is connected to the carriage for the measurement of the magnitude and direction of the fluid flow speed at a number of measurement points.
