The response rate and the angular characteristics of a cylindrical electrode for measuring liquid velocity is discussed. By the experiment and the dimensional analysis the experimental equation for response rate is obtained. In the both cases of the liquid velocity increase from 0 cm/s to a [cm/s1 and the liquid velocity decrease from u [cm/ s] to 0 cm/s, the response rate is in proportion to d/u (d is probe diameter). In the case of the liquid velocity changes from u1 [cm/s] to u2 [cm/s], the response rate is in proportion to d/u2/u12 in u1<u2, and is in proportion to d/(u1u2) 1/2 in u1>u2. As the slowest response rate is obtained in the case of the liquid velocity decrease from a icm/s] to 0 cm/s, this response rate should be considered as the most important factor in using this electrode probe.
And it is become evident after examining the experimental results of the angular characteristics that the direction of the main flow can be determined by rotating this cylindrical electrode in the flow field.
