ABSTRACT:
A method and apparatus for determining mass throughput of material to be conveyed through an essentially closed conveying system. In addition to a mass measuring device for determining the throughput of a flow of a conveying fluid carrying the material to be conveyed, there is provided a second measuring device for determining the mass of conveying fluid supplied to the conveying system. Subtracting the values measured results in a very accurate indication of the mass of material momentarily conveyed, without error caused by the conveying fluid.
