Analysis of impact of the roughness of the surface of the nozzle flowmeter on the value of its coefficient of discharge. The study built on the basis of modern theory of the boundary layer and on the compliance of the method, allowing the degree of influence of this disturbing factor on the static characteristics of primary device and obtain the corresponding correction function.
