Description

The main advantage of the invention is that

The invention relates to a device 40 that the flow profile at both small and for recording a flow profile using at high flow velocities over a tion of a given measuring length provided with several inclinometers is determined exactly. the A cable that is at least measuring length in the flow cannot be changed by external influences Buoyancy body worn and at the bottom bar, since the device according to the invention is all End is attached. 45 flow conditions automatically and continuously

The cone bodies adjust to a correct, constant inclination is no longer sufficient, which is adjusted according to the flow conditions, with propulsion bodies being used in addition to setting the conical position at a certain point in time through a constant inclination of the rope,
