Abstract: The invention relates to a microwave measuring device for detecting the charge of a two-phase flow with a gaseous carrier medium containing small and minuscule solid and /or fluid particles and for detecting gas contained in a fluid flow, preferably by means of waveguide carrier waves. A preferred application of the invention is the detection of solid particles contained in the flow of gas of voluminous pneumatic solid matter transport systems used, for example, for pulverized coal furnaces of coal power stations. The inventive microwave measuring device is provided with field rods, which protrude into the inside of the feed pipe, are arranged before and after a measuring section formed by a transmission antenna and a reception antenna, said rods interacting with the feed pipe made of conductive material as a resonator for microwaves injected into the feed pipe via the transmission antenna, whereby microwaves that differ from the injected microwaves in their plane of polarization and/or phase as a result of diffraction, superposition, and/or reflection outside the measuring section are essentially short-circuited in order to prevent the results of the measurement from being distorted. The inventive device has the particular advantage of being simple to build and easy to install even in voluminous and branched feed pipe systems.

Abstract: A method of determining the quantity of particulate matter suspended in a carrier gas in a pipe by measuring the frequency shift over a substantially linear range of an attenuation curve below the cut-off frequency for wave propagation, the curve being derived from measuring the attenuation of an electric field established in a conductive pipe substantially free of wave propagation.

Abstract: An apparatus and a method for producing samples of a finely granular and dry material for measuring the residual carbon content thereof. The material is fed by a torque monitored conveyor screw to a measuring chamber and is progressively compacted therein. At an abrupt increase in screw torque feeding of the material ceases yielding a sample in the measuring chamber of a reproducible degree of compaction.
