ABSTRACT:
The invention proposes a novel weighing method and a device for exactly determining the weight of a continuous stream of bulk material. The stream is conveyed without interruption into a tubular weighing machine (1). A blocking slide valve (4) is cyclically closed and opened and the weight increase per unit time is measured, the slide valve (4) being closed in each case, and an average is obtained from a very large number of weighing operations repeated in the same manner, and is used by computer means (5) for calculating the entire amount of bulk material. The weighing cycle is very short, in some cases less than 10 seconds, and is continuously repeated. The large number of measurements gives high statistical accuracy of about .+-.0.02%, i.e. of the same order as for a container-type weigher.
