   PATENT CLAIMS:
1. A method for measuring the amount of a dust-like substance conveyed by means of air or some other medium, in particular coal dust, characterized in that the flow rate in the conveying air line and in the mixture line is measured separately and the measurements are applied to one of the
Difference indicating device are transmitted.

Claims (1)

2. Vorrichtung zur Ausführung des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass in beiden Leitungen Messdüsen eingebaut sind und zur Messung des Druckunterschiedes vor und nach der Düse und damit zur Messung der durch die Leitung strömenden Menge an beide Leitungen Druckunter- schiedsmesser angeschlossen sind, die im entgegengesetzten Sinne auf eine gemeinsame Anzeigevorrichtung einwirken. 2. Device for performing the method according to claim 1, characterized in that measuring nozzles are installed in both lines and for measuring the pressure difference before and after Nozzle and thus for measuring the quantity flowing through the line are connected to both lines pressure difference meters, which act in opposite directions on a common display device. 3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, dass als Anzeigevorrichtung ein elek- triches Messgerät vorgesehen ist, auf welches im entgegengesetzten Sinne zwei. Ströme einwirken, die durch die Druckunterschiede an den beiden Messstellen beeinflusst werden. 3. Device according to claim 2, characterized in that an electrical measuring device is provided as the display device, to which two in the opposite sense. Currents act that are influenced by the pressure differences at the two measuring points. 4. Vorrichtung nach Anspruch 3, dadurch gekennzeichnet, dass die Teilströme mittels Solenoiden (15 und 21) und in diesen angeordneten Eisenkernen (22 und 23) auf einen doppelarmigen Hebel (24) einwirken, der einen über einer Teilung schwingenden Zeiger trägt. EMI2.2 4. Apparatus according to claim 3, characterized in that the partial flows act on a double-armed lever (24) which carries a pointer oscillating over a division by means of solenoids (15 and 21) and iron cores (22 and 23) arranged in these.
