Abstract

A device disclosed to detect the speed profile of concrete flowing through a pipeline with radial symmetry comprises acoustical probe means, adapted to send through said pipeline and the concrete a supersonic ray inclined in respect of the pipeline axis and to receive a disturbed supersonic ray in response, as well as an electronic circuit adapted to analyse the signals sent by said probe means and obtain therefrom a diagram showing the speed profile of the concrete. The probe means make use of a supersonic ray of frequency between 20 and 500 KHz, and said electronic circuit processes the signals sent by the probe means, indicating the speed, with an updating frequency from 10 to 70 times per second and deprives said signals from their components derived from the propagation rate in the concrete, to obtain a measurement of the speed along the acoustical axis, which is not relative and has its own sign.
