| Abstract: | Evaluation has been made of the existing flow measurement techniques. Selective and adoptive models which apply to the flow measurement techniques of different U-shaped channels have been given. Studies are done on the design and standardization of flat parabolic non-floated segment of U-shaped channel flow measurement flume and, by using the form coefficient of the parabola (P) as the index, 28 standard flumes are proposed. The examinations and observations both in the lab and on the spot have shown that measured values are identical with the theory value, which indicates that the flume can meet the demand of water measurement. |
