Abstract

A suction nozzle is provided for a fan with a suction opening for suctioning a fan main flow. The suction nozzle has an opening edge section adjoining the suction opening and having a local outbreak. A flow insert is detachably provided in the local outbreak of the opening edge section. The flow insert forms a bypass leading to the suction opening for a bypass flow leading to the fan main flow. Measuring means are provided in the bypass for the volume flow determination of the fan main flow. A confusor is provided in the bypass. The confusor is formed by a first web and a second web. The first web and the second web circumferentially face one another to form a nozzle channel in the bypass. The nozzle channel has a radially narrowest section. The measuring means are arranged in the radially narrowest section.
