In this article was proposed the solution of installation for gas flow measurement with face-end nozzles using. An experimental research was carried out to determine the complex flow coefficient used in the face-end nozzles. Metrological research of installation was realized for gas flow measuring by determining the standard uncertainty components of total uncertainty and developed its metrological model.
