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.
