Problems solved by technology

However, this becomes a problem when flowmeters with different housing sizes and / or different flow channel lengths are to be provided, since in this case the rectifiers are at different distances from the measuring area, which in turn can lead to different flow profiles in

Embodiment Construction

[0051] figure 1 A flow meter 1 for detecting fluid flow is shown. The housing 2 of the flow meter has a flow channel 3 through which the fluid can flow and which extends from the inlet opening 4 to the outlet opening 5 . The flow meter 1 is an ultrasonic measuring instrument. In this case, ultrasonic waves are emitted by the first ultrasonic transducer 24 and received by the second ultrasonic transducer 25, and vice versa. From the difference in travel time, the flow velocity can be calculated and, therefore, the flow rate when the flow cross-section is known. The control of the ultrasonic measuring instruments 24, 25 and the acquisition and processing of measurement data are performed by a control device (not shown). In order to pass the ultrasonic waves through the flow channel substantially parallel to the flow direction, the flow meter 1 also has reflecting elements 26 , 27 .

[0052] In order to be able to measure the flow more precisely, the flow meter 1 has a measur...

Abstract

The application discloses a flow meter for detecting fluid flow, comprising: a housing (2), the housing (2) has a flow channel (3), through which fluid can be guided from the housing inlet opening (4) to the outlet opening (5) of the housing (2); the measuring tube (6), which is inserted into the flow channel (3) and in a part (17) of the flow channel (3) ) so that the flow cross-section is constricted; and a holding device (7) by which the measuring tube (6) is held on the housing, wherein a corresponding rectifier (8) is arranged between the inlet opening and the measuring tube and / Or between the measuring tube and the outlet opening, the rectifier has at least one hole (9) through which the fluid can flow, wherein the rectifier is designed as a separate part, which is fixed in the holding on the device. The present application also discloses a method for manufacturing a flow meter for detecting fluid flow.

Description

technical field [0001] The invention relates to a flowmeter for detecting fluid flow, comprising: a housing having a flow channel through which fluid can be guided from an inlet opening of the housing to an outlet opening of the housing; a measuring tube, The measuring tube is inserted into the flow channel and restricts the flow cross-section in a portion of the flow channel; and a holding device by which the measuring tube is held on the housing. In addition, the present invention also relates to a method for manufacturing a flow meter. Background technique [0002] The flow through the flow channel can be measured by an ultrasonic meter. In this case, two ultrasonic transducers are used, one of which transmits ultrasonic waves and the other receives them. By measuring the propagation time of the ultrasonic waves between these ultrasonic transducers or the difference in propagation time between the directions of transmission, the flow velocity can be detected and therefo...
