METHOD AND APPARATUS TO DETECT CONTAMINANTS IN PRESSURIZED FLUID FLOWS

摘要

Method and apparatus for the detection and measurement of contaminant concentration within pressurized fluid flows in real‐time. The provided method and apparatus allow for real‐time detection of black powder contaminants in pressurized gas flows by irradiating the flow with electromagnetic waves generated by hermetically‐sealed electromagnetic wave radiators and measuring wave characteristics. An image is rendered of the spatial distribution of black powder within the pipe cross section, and mass flow of the contaminated gas is measured.
