Abstract

For measuring the flow rate of a thin stream of molten materials such as that of glass, the diameter of the thin stream is measured, as is the velocity. The velocity is measured on the basis of the measurement of the time separating the successive appearance of an emission sequence emitted at first and second points on the path of the molten material. A correlation is then established between the sequences and the time interval corresponding to the passage of the same irregularities at the two selected points identified by this correlation.
