[0004] However, when using the above method, it is necessary to arrange observers to observe in real time when quantitative distribution is performed through the scale, and it is easy to cause large errors by observing the coincidence of the liquid level and the scale. When the observer's line of sight is at a different angle to the scale and the liquid level, the final observation result will also be different, making it impossible to accurately and effectively perform quantitative distribution during actual operation.
