| Abstract: | Some problems of using Hampson level gauge in determination of liquid level with gaseous transmission differential pressure were discussed. According to the working principle of Hampson level gauge, as it is installed and used, gaseous phase must be ensured for transmitting signal condition. Thus, it is necessary to maintain stable base point in determination, to install gasifier with heating apparatus and to apply triplet valves. |
