<p>With a possible aim to provide an ultrasonic consumption flow meter 102 where precision of measurements can be improved while also providing a precise and consistent assembly and positioning of components of the flow meter, there is disclosed a flow meter housing 104 with a pair of holes 302 through a material thickness 412 of the housing, a pair of connection pieces, 112a and 112b, each connecting the flow meter housing and one ultrasound transducer 116. A connection piece is provided with a holder 702 for holding an ultrasound transducer and a base 706 for positioning the connection piece in the flow meter housing. An inner surface 404 of the base 706 has a geometry which, apart from an opening 406 leading towards the ultrasound transducer positioned in the holder, is the same or substantially the same as a geometry of an inner surface 408 of the flow meter housing.</p> |
