Analysis of U-Shaped Channel Flow Measurement Flume Properties and Selection

Using simulation method, the applicability, backwater height, cerement volume, flow measuring precise of vertical wall, parabolic thin-plate, circle flume types of U-shaped channel flow measurement are analyzed. The results show that the parabolic thin-plate flume which has extensive applicability, small backwater height, less cerement volume, high measuring precise for small U-shaped channel flow measurement, is the optimal flow measurement flume for U-shaped channel in muddy irrigation district.
