摘要：In order to measure the degree of filling of a dust collector (), where the dust ()collected in the dust collector may be of a very varied composition ranging from very fine

dust () to rather large particles (), a high pressure difference and a low pressuredifference are measured by two differential pressure meters (), where the onedifferential pressure meter () measures the pressure difference between thecompartment () of the dust collector, in which the dust collector () is arranged, and ameasurement position at the connecting stub () of the vacuum cleaner, as is known, whilethe other differential pressure meter () measures between two measurement positionsinside the connecting stub (). Hereby, the method and the filling indicator according tothe invention will ensure that larger particles do not settle inside the connecting stub ()since these are detected beforehand by the differential pressure meter () which recordslower pressure differences that the differential pressure meter ().
