Inductive methods of detection the boundary of electrically conductive media in experiment

Induction methods of localization the electrically conductive media were implemented experimentally. Local and integral techniques are considered. Relations were represented between of the local level probe (LLP) signal, its position and the frequency of alternating current. The dependences of the integral level probe (ILP) signal on the frequency of the alternating current are obtained. The methods were tested in laboratory experiments in which it was possible to determine the metal level with an error not exceeding 1 mm. The LLP is more designed for small changes in the liquid metal boundary, comparable to the size of the probe. The ILP has its advantages when used in installations in which the change in the level of the liquid metal is greater than the pitch with which the measuring coils are installed.
