More Information
Summary:A method is presented for determining at least one piece of information representative of a phase fraction of a fluid in a pipe. The method comprises the estimation of a number of counts received in each measuring interval based on each piece of representative information determined at a preceding iteration, then calculating a residual comprising a first criterion calculated from probabilities using a given statistical law to measure, for each energy, the number of counts measured in each interval, the given statistical law being parameterized based on the number of estimated counts.
