This paper presents a survey on methods of measuring airflow, especially methods using inlet nozzles. Methods are compared with respect to uncertainties due to nozzle shape and/or measurement, handling friendliness, and economics. Authors describe a new nozzle contour with a constant air velocity along its surface. They explain advantages and disadvantages of this new design.
