  1. 1.

    Despite the tedious adjustment of the high frequency circuit and the relatively complex calculations involved, the present work confirms the advisability of using the new method of investigating the structure of the flow of an air and water mixture in vertical pipes, based on the sharp difference between the permittivities of water and air.

  2. 2.

    The proposed method of investigation is more accurate than other methods; it provides not only mean values of air content in the mixture with respect to the height, and the cross section of the pipe, but also data on the distribution of the air along the cross section of the pipe.
