REAL-TIME METHOD FOR THE DETECTION AND CHARACTERIZATION OF SCALE |
摘要 |
A method of identifying scales on a surface of a passage through which a fluid is passing is provided. The method includes the following steps. First, second, and third values are determined. The first, second and third values are related to attenuation of the fluid for first, second, and third energy levels respectively at which energy is emitted through the fluid. It is determined first and second fluid ratios r1f and r2f between the first and second values and between the second and third values respectively. It is determined for a plurality of scales theoretical values related to attenuation of each scale of said plurality of scales for said first, second, and third energy levels. For each scale of the plurality of scales is determined a first ratio r1 s between said first and second scale values and a second ratio r2f between said second and third scale values. Scales are identified based on comparison between (r1f, r2f) and (r1s, r2s). |
