A laboratory rig designed for evaluation of
measuring methods applied to the fluid flow
in a pipe

The paper presents a laboratory rig designed for evaluation of the both,
single- and two-phase flow measuring methods. Especially the paper
focused on application of nuclear methods to measurement of a stream
velocity in a horizontal pipe with future possibility of a gas phase inclusion.
As an example, a comparison of water velocity measurements by
radiotracers and ultrasonic meter was presented.
Keywords: velocity and flow rate measurements, nuclear methods, radiotracers,
ultrasonic flow meters.
