The invention relates to an apparatus for determining properties of a medium flowing through a cross-sectional area. Said apparatus has at least one sensor comprising at least one transmitting device for injecting electromagnetic and/or acoustic radiation into the medium and at least one receiving device for generating a measurement signal on the basis of radiation reflected in the medium or radiation transmitted by the medium. An evaluation device is also provided, which evaluation device determines the property of the medium on the basis of the measurement signal. According to the invention, the at least one transmitting device and the at least one receiving device or a measuring head are rotatably arranged at least approximately in the centre of the cross-sectional area and are designed in such a manner that the direction of the emitted radiation is inclined by an angle with respect to an axis running substantially parallel to the direction of flow of the medium and the rotational position of the direction of radiation around the axis is variable.
