摘要： An apparatus for measuring the flow rate of a stream of material includes an impeller shaft; an impeller wheel secured to the impeller shaft; a first roller bearing having an inner race receiving and supporting the impeller shaft; a drive motor having an output shaft; a first gear secured to the output shaft; a second gear secured to the impeller shaft; and a third gear meshing with the first and second gears, whereby the drive motor is drivingly connected to the impeller shaft by the first, second and third gears for rotating the impeller shaft with a predetermined rpm. The stream of material is directed onto the impeller wheel, whereby a braking torque is applied to the impeller wheel by the stream of material impinging thereon. There are further provided a force measuring device operatively coupled to the third gear; a second roller bearing receiving and rotatably supporting the outer race of the first roller bearing; and a drive for rotating the outer race with an rpm which is at least identical to the rpm of the impeller shaft.

摘要： For measuring a preferably heterogeneous mass stream there is a class of measuring apparatus that uses a rotary member carried by a shaft and driven at constant speed, said rotary member deflecting radially the mass stream acting axially upon the rotary member, thereby giving it a tangential velocity component. The torque dependent on the mass stream is measured on the shaft. For this purpose a first spur wheel is provided on the shaft, that meshes with a second spur wheel. The second spur wheel is mounted in a carrier member that is in turn mounted so as to rotate about the axis of the shaft and held in position by a forcesensing device. To improve the measuring sensitivity the second spur wheel has a second toothed engagement opposite the first spur wheel with an internal toothed wheel rim which is also mounted so as to rotate about the axis of the shaft and set rotating by a driving pinion. A rotational body set rotating in the same direction as the shaft is in frictional engagement with the carrier member and/or the first spur wheel. The strength of the hydrodynamic frictional engagement is coordinated in such a way that the moments of friction of the first and second spur wheels are compensated by the moment of friction of the frictional engagement.

摘要： A metering slide for fine-grained solids for gastight closing and cross-section-variable opening of vessels and piping in pneumatic conveying systems. A sliding plate provided with a metering opening is moved between two slide rings by a drive in a compression-proof slide casing. The intake side slide ring opening has a predetermined nominal width between 1/10 and 1/3 of the outside diameter of the slide ring. The discharge side slide ring has an inside diameter corresponding to 3 times to 10 times the nominal width of the intake. The slide casing is filled with a lubricant which is under a pressure equal to or higher than the operating pressure of the penumatic conveying system.
