Abstract
Measurement of the oil-water flow is of great importance in the industrial process. In the paper, a soft-measurement method for oil-water mass flow-rate was brought forward, in which the V-cone differential pressure meter was used and the adaptive wavelet network was developed to achieve the soft-measurement of the mass flow-rate. The multi-input single output model of adaptive wavelet network was adopted to approximate the mass flow-rate of oil-water. The paper focused on the experimental measurement of the homogeneous model of oil-water two-phase flow in horizontal pipe. Experimental results showed that the soft-measurement method combined differential pressure with adaptive wavelet network could satisfy the demand of the mass flow-rate measurement and the measurement error of the mass flow-rate was relatively small. The measurement error of the total mass flow-rate was acceptable.
