This paper presents original work concerning modified measurement method, related processing technique and output values forming. The method introduces extended length between pressure measurement points in pipes filled with open cell metal foam. It is proven theoretically and practically that increased distance between pressure sensors assures self-affinity of differential pressure signal. The modified fractal dimension determination procedure accepts different statistical parameters recursively determined on input signal and outputs fractal dimension D and B-parameter. For flow regime distinguishing the two B-parameters mainly B_mean and B_std are needed. The measurement method proves universality of proposed method for all investigated flow regimes regardless of mixture and foam parameters. The method can be used for industrial type active flow regime control as well as for scientific activities.

本文介绍了有关改进的测量方法，相关的处理技术和输出值形成的原始工作。该方法在充满开孔金属泡沫的管道中的压力测量点之间引入了延长的长度。理论和实践证明，压力传感器之间的距离增加可确保差压信号的自亲和性。改进的分形维确定过程接受输入信号上递归确定的不同统计参数，并输出分维D和B参数。为了区分两个B参数的流动状态，主要是B_平均值和B _std是必需的。该测量方法证明了所提方法在所有研究的流态下的通用性，无论混合物和泡沫参数如何。该方法可以用于工业类型的主动流动状态控制以及科学活动。
