DETECTION OF AN ELEMENT IN A FLOW

摘要

A method of detecting an additional element from a plurality of other elements forming a multiphase flow. The method comprising: measuring an energy spectrum response based on electromagnetic irradiation of the multiphase flow. Determining a fraction concentration of the other elements forming the multiphase flow based on a lower energy peak in the spectrum response and detecting an additional element in the multiphase flow based on measuring a variation of a higher energy peak in the spectrum response. It is also possible to measure the quantity of the additional element and to compensate the fractional concentrations of the respective n-phase measurements.
