| Abstract: | Quick and accurate measurements of falling-firm absorbent LiBr liquor concentration is very important for the analysis of heat and mass transfer performances. A new digital liquor concentration measuring system with the Electromagnetic Torque Feedback was designed based on common manual balance, the structure of the system was described and the falling-firm liquor concentration can be obtained by the system automatically. |
