| Abstract: | The pressure of four kinds of different diameter and three kinds of different bending diameter ratio of 90° circular pipe flowmete are numerically simulated and experimentally studied The radial distribution of pressure,pressure distribution of inside and outside wall,the impact of bending diameter ratio,the best profile to measure and flow coefficient of different bending diameter ratio and diameter are described. |
