Abstract
The invention relates to a flow meter for liquid or gaseous media, the flow meter has a measuring channel through which the medium flows, at least one inlet channel and at least one outlet channel and also at least one pair of ultrasound converters for emitting and receiving ultrasound signals, wherein for guiding an ultrasound signal from one ultrasound converter to the other ultrasound converter, at least one pair of reflectors is arranged in the measuring channel, the diameter of the measuring channel is reduced using a reducer in certain regions for guiding the flow of the medium, wherein the reducer is formed by a measuring channel insert, which is arranged on and/or integrated into the measuring channel inner wall, and which is used simultaneously for holding or fixing other functional parts. Furthermore, the invention relates to a flow meter, in which a flow guide plate is used as a holding plate for the pair of reflectors and stretches in the longitudinal direction of the measuring channel. In another embodiment at least two measuring sections each having at least one pair of reflectors and one pair of ultrasound converters are provided.
