Abstract

The invention relates to a fluid meter (1) having a measuring tube housing (2), a measuring zone (3) inside the measuring tube housing (2), an ultrasonic transducer configuration of at least one ultrasonic transducer (4 and/or 5) for generating an ultrasonic signal and/or converting an ultrasonic signal passing through the measuring zone (3) into an electric signal and a deflecting device (11) for deflecting the ultrasonic signal in particular in the longitudinal direction of the measuring tube (3) such that the surface normal N of the ultrasonic transducer (4 and/or 5) is arranged so it is inclined laterally based on the top position of the fluid-filled interior of the measuring tube housing (2) in the installed position with the plane E such that the ultrasonic signal does not strike the deflecting device (11) from above in the installed position of the fluid meter (1).
