Abstract

A device for measurement and/or control of the volumetric flow in a mass (6) of material is characterised in that it includes comprises a non-contact speed measuring means (1) in combination with a non-contact measuring means (2), such as a visual angle measuring means or a width measuring means, where the measurement takes place directly on the object, for example for measuring diameter, edge, width, and the like, the output signals of said two measuring means being supplied to a computing device (3) for the volumetric flow, the output signals of which are a measure of this flow and may be supplied to a control device (5) for regulating the volumetric flow which the device is especially adapted for use in connection with materials which are difficult to handle, such as molten glass, corrosive fluids or bar material in a plastic state. <IMAGE>
