摘要：Measurements of stream flows are very common in the power industry. High parameters of the fluid, its impurities or the complexity of the flow installation make often such measurement problematic. Flow disturbances are a factor that significantly increases measurement uncertainty. The paper presents an example the measurement problem solution based on mathematical modelling and digital flow simulation. The problem was the measurement of the air stream in a complex mill air flow installation. A measuring system based on a probe averaging dynamic pressure has been developed. The location of the probe was determined by numerically modelling the flow in the considered section of the mill air installation. Monthly observations of the measuring system operation confirmed its high usefulness in the operation of the mill installation.
