| Abstract: | The difficulties in field measurement of material level for "fly ash/bottom slag" island in 600 MW large power plants were analyzed. The difficulties include the catching of variation law of the working mediums such as temperature, pressure, material conveying speed and dielectric constant and no ready made control model for reference. From multiple views of type selection design, new technology application, PLC/DCS interface and the measuring principle of material level measuring sensor and so on, new concepts and recommendations for discrimination, analyzing and practical problems solving were put forward. |
