Embodiment Construction

[0044] figure 1 A longitudinal cross-sectional view of the flow meter 1 including a conduit 3 is shown that forms a pipe 2 through which the fluid to be measured flows. In the example shown, the pipe 2 is cylindrical of revolution and includes a longitudinal axis 4. The catheter 3 includes two brackets 20 ( image 3 ), the two brackets are molded or processed on the pipe, and are opposite in diameter relative to the pipe and spaced apart from each other along the longitudinal axis of the pipe. Each bracket 20 includes an opening leading to the pipe 2. An assembling device 5 for assembling the ultrasonic transducer 9 is installed in the opening of each bracket 20 and fixed on the pipe 3.

[0045] figure 2 with image 3 The assembling device 5 shown in more detail in includes a body 6 formed as a single piece, which body is preferably molded of a synthetic material (for example, polyetherimide (PEI)) for temperature stability, and The shape of the body is at least partially conj...

Abstract

The invention relates to a device (5) for mounting an ultrasonic transducer (9), suitable for mounting said transducer such that it extends through a wall of a flow meter (1) having a channel (2) in which a fluid (19) flows; the device comprises a body (6) in communication with an inner surface (16) of said channel in accordance with a closed contour line (14) that forms an interface between the inner surface of the channel and a surface of the device body, referred to as active surface (15), which follows the shape of the inner surface of the channel. The active surface extends continuously,and without openings, in the area delimited by the contour line. The invention also relates to a flow meter using a mounting device of this kind.

Description

Technical field [0001] The present invention relates to an assembling device for assembling an ultrasonic transducer, and more particularly to such a device suitable for assembling the transducer in a pipe of a flow meter. The invention also relates to a flow meter equipped with such an assembly device. Background technique [0002] There are many kinds of ultrasonic flowmeters in which the fluid flow rate is measured by the propagation speed of ultrasonic waves in a fluid medium circulating in a pipe. [0003] The present invention is applied to a flow meter in which the transducer or at least the assembly device for assembling the transducer passes through the wall of the pipe to come into contact with the fluid whose flow is to be measured, which interacts with the transducer and / Or an assembling device for assembling the transducer is installed outside the pipe and performs measurement by transmitting waves through the wall of the pipe, on the contrary. [0004] An ultrasonic ...
