Problems solved by technology
In the hydrodynamic environment, the problem of accurate measurement of suspended sediment concentration in water bodies has not been solved. Different water environmental conditions will affect the measurement results of suspended sediment concentration. Effect of Concentration Field
[0003] The current construction of the suspended sediment concentration field mostly adopts the preparation of the suspended sediment concentration field in a bucket, and stirs the water-sand mixture with a stirrer. If the uniformity test of the suspended sediment concentration field is not carried out, the suspended sediment concentration field is considered to be uniform. Calibration of suspended sediment concentration measurement equipment does not meet the calibration requirements in the field of metrology and testing technology

Abstract
The invention discloses a method and a device for preparing a standard suspended sediment concentration field. The method for preparing the standard suspended sediment concentration field comprises the following steps: weighing materials; stirring the solution; testing the uniformity of the suspended sediment concentration field; preparing a standard suspended sediment concentration field. The standard suspended sediment concentration field with the standard suspended sediment concentration value can be provided in the flowing water environment, the calibration requirement of suspended sediment concentration measuring equipment is met; therefore, it is ensured that suspended sediment concentration measurement is more accurate.
Description
technical field [0001] The invention relates to the technical field of calibration of suspended sediment concentration measuring instruments, in particular to a method and device for preparing a standard suspended sediment concentration field. Background technique [0002] The value of suspended sediment concentration in water is the mass of dry sediment carried in a unit volume of water sample, which is used to study reservoir sedimentation, port channel sedimentation, channel transportation, water quality environment and beach soil erosion and other issues important parameters. In the hydrodynamic environment, the problem of accurate measurement of suspended sediment concentration in water bodies has not been solved. Different water environmental conditions will affect the measurement results of suspended sediment concentration. The effect of the concentration field. In the process of constructing the standard suspended sediment concentration field, how to reproduce the ...
