In the preceding paper, the author stated the characteristic of the current meter with its axis placed parallel to the flow. In this report, however, he has studied the characteristic curve of the current meter in the tilt flow and classified current meters into four categories in accordance with the aerofoil of its runner and with the error on its indicated velocity subject to the tilt flow. By combining characteristic curves of more than two out of the simplified runner, the author has succeeded in trial production of the combined aerofoil current meter, which satisfies Cosine law under the influence of the tilt flow.
