Method and apparatus for determining the fractions of between the liquid is not conductive and steam, or between the solids not conductive and gas, in particular for fuels containing solid particles

摘要

P & this process and apparatus for implementing the measure of the fractions of the relative phases in the fluid media. Use is made of a transparent electrically conducting section (,) of the tube where the flow control, a sensor surrounding this section and is composed of two envelopes semi - concentric circular that pass through the conductors provided with a terminal to the outside, and an electrode in the form of elongate plate in the axial direction to the inside, a switching circuit to control the excitation, in succession, the electrodes without any overlap in the space of some electrodes, each electrode is excited and the transmitter being opposite to a plurality of electrodes excited and receiving, in turn. This method and apparatus are applied to the crude oil or their derivatives, when they contain the solid particles. / p
