MICROWAVE MEASURING DEVICE FOR DETECTING THE CHARGE OF A TWO-PHASE FLOW

摘要

A microwave measuring device for defining the load of a two-phase flow of a gaseous carrier medium and at least one of small and minute solids and liquid particles and for defining the gas contained in a fluid flow, comprinig: a feed duct section made of electrically conductive material for accommodating two-phase flow; a treansmission antenna and a receving antenna mounted in the feed duct section at a predetermined space from each other for forming a measuring path therein; first and second electrically conducitive filed rods respectively mountes in the feed duct to extend into the interior therof of ahead of and behind the measuring path and aligned with the transmission and receving antennae for forming resonator in the section of the feet duct between the first and second filed rods.
