A throughflow measurement system for measuring a fluid throughflow through a pipe includes a first measurement arrangement having at least two ultrasonic transducers and that is configured to determine a value for the fluid throughflow through the pipe on the basis of transit times of ultrasonic signals transmitted and received with and against the flow. A second measurement arrangement includes a plurality of hot-wire sensors that are arranged distributed over the cross-section of the pipe and that are each configured to determine a local flow value. An evaluation device is in signal connection with the first measurement arrangement and the second measurement arrangement and is configured to determine a flow profile on the basis of the local flow values determined by the hot-wire sensors and to modify the value for the fluid throughflow, which is determined by the first measurement arrangement, on the basis of the determined flow profile.

Throughflow measurement system

A flow conditioner for conditioning a fluid flow comprises a pipe that has a pipe axis and that can be flowed through by a fluid in the direction of the pipe axis; and at least one hub body that is rotationally symmetrical with respect to an axis of symmetry and that is fixed in the pipe such that the axis of symmetry coincides with the pipe axis, wherein the hub body fixed in the pipe has an onflow region that is arched outwardly against the onflow direction.

Flow conditioner

The invention relates to a measurement apparatus for measuring a flow rate of a fluid that flows with a main direction of flow in a circular line comprising an inlet section for conducting the fluid from the circular line into the measurement apparatus; an outlet section for conducting the fluid from the measurement apparatus into the circular line; a measurement section for connecting the inlet section to the outlet section; at least one ultrasound device for transmitting and/or receiving ultrasound waves, wherein the ultrasound device is arranged at a wall of the measurement section; and an evaluation unit for carrying out a time of flight difference measurement and for determining the flow rate, wherein the inlet section has a first superelliptic transitional shape and the outlet section has a second superelliptic transitional shape and the measurement section has a rectangular form, in particular having rounded corners.
