| Abstract: | The weighting method is usually adopted to measure the volume of tanks, but its measured value has a great deviation from the theoretical value. The reasons that the deviation occurs in the process of manufacture, hydraulics test, medium filling, weighting, volume calculation and distortion are analyzed. The deviation value of each link is also analyzed by means of an example of tank volume calculation. Some solutions for decreasing the deviation and a modification scheme regarding with tank volume measurement are proposed in this paper. |
