The disclosure relates to a retaining device for an anemometer, designed for use on a fan housing of a fan, wherein the retaining device is designed as a flow conditioner having a plurality of axial flow channels divided into a honeycomb structure by an arrangement of bars, and wherein the retaining device has retaining means, by means of which the anemometer can be fastened to the retaining device such that the former axially adjoins the flow channels.

Retaining device for an anemometer, and centrifugal fan

A radial fan has a housing with a motor-drivable fan wheel. The fan wheel generates an air volume flow during operation. The housing has a blow-out portion () with an impeller (). The impeller () has a plurality of impeller blades () spaced apart in the circumferential direction. The impeller () is driven by the air volume flow generated by the fan wheel.

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.
