Embodiment Construction

[0045] figure 1An ultrasonic counter of the described type is shown, which has a housing 1, an ultrasonic transducer 2 and a further ultrasonic transducer 3, which are each mounted on the side of the housing 1 via a housing opening provided for this purpose. It is fastened in the wall of the housing 1 by means of an associated cover with a seal.

[0046] A turning mirror 5 is correspondingly arranged for the ultrasonic transducer 2 , and another turning mirror 6 is correspondingly arranged for the other ultrasonic transducer 3 . The measuring section 4 (that is to say the course of the acoustic signal) is from the ultrasonic transducer 2 to the turning mirror 5, from the turning mirror to the other turning mirror 6, from the turning mirror 6 to the other transducer 3, from the turning mirror The transducers return in the opposite direction, so that the measuring section is U-shaped, but it is also possible within the scope of the invention to have additional deflection mirror...

Abstract

The present invention relates to a ultrasonic flowmeter for measuring flow of flowing medium, particularly flowing liquid or gas, which has a housing (1); a measuring section (4) that set inside the housing (1) along which a differential time of flight measurement can be made; at least an ultrasonic transducer (2) and a ultrasound mirror (5) for guiding the sound beam. Wherein, fluid flow guidingelements are provided in the area of the mirror surface to optimize the fluid flow over the mirror surface.

Description

[0001] This case is a divisional application of a patent application with an application date of September 29, 2004, an application number of 200410083200.4, and an invention title of "ultrasonic counter for determining the flow rate of a flowing medium". technical field [0002] The invention relates to an ultrasonic counter for determining the flow rate of a flowing medium, in particular a liquid or a gas. Background technique [0003] DE 201 07 894 U1 discloses an ultrasonic flowmeter of the type mentioned. Here, the upper edge of the deflecting mirror facing away from the fluid is flowed around by the medium, so that a recirculation zone or zone of reduced flow velocity is formed in the surface area of ​​the first deflecting mirror, which can lead to contamination of the deflecting mirror. This also affects the long-term stability of the ultrasonic flowmeter. [0004] DE 199 30 278 A1 describes an ultrasonic counter having a first deflecting mirror which comprises holes...
