Problems solved by technology

Backing-up effects can occur when the measurement region (in which the flow cross-section is constricted) is relatively close to the reflective element, however, this can lead to flow sudden change in distribution
This can lead to a kink in the characteristic curve of the ultrasonic measuring device, which can lead to a measurement error of up to 3%, for example
Corresponding effects cannot be electronically compensated in a reliable manner, since transition points between different flow profiles can vary, for example as a function of temperature or aging

Embodiment Construction

[0030] figure 1 and 2 A sectional view of an ultrasonic measuring device 1 for recording the through-flow velocity of a fluid is shown. Here the two figures represent the same cross-section, where, figure 1 An oblique view is shown so that the components of the ultrasonic measuring instrument 1 are shown perpendicular to figure 2 The extent of the drawing plane.

[0031] The ultrasonic measuring device 1 has a fluid inlet 2 , a fluid outlet 3 and a flow channel 4 which connects the fluid inlet 2 to the fluid outlet 3 . The flow channel 4 comprises a measurement region 5 , which extends linearly in the flow direction, in which measurement region 5 the fluid is guided through the ultrasonic measuring device 1 . Between the measurement region 5 and the fluid outlet 3 there is arranged a reflective element 6 around which the fluid can flow and through which ultrasonic signals from the ultrasonic transducer 7 can be reflected into the measurement region 5 or vice versa, The u...

Abstract

An ultrasonic meter for recording a through-flow rate of a fluid has a fluid inlet, a fluid outlet, and a flow channel connecting the inlet to the outlet. The flow channel has a measurement region which extends in a straight line in a flow direction. Between the measurement region and the fluid outlet, there is arranged a reflection element which is flowed around by the fluid and by which an ultrasonic signal of an ultrasonic transducer arranged on a side wall is reflected into the measurement region or otherwise, and the side wall defines a flow section of the flow channel. Between the measurement region and the reflection element, there is arranged a changeover region of the flow channel. In the changeover region a spacing between a central straight line of the measurement region and theside wall enlarges in a stepwise or continuous mode. The changeover region has, in the circumferential direction of the flow channel, several circumferential sections in which the enlargement of thespacing between the central straight line and the side wall takes place. The enlargement position is different when seen along the flow direction.

Description

technical field [0001] The invention relates to an ultrasonic measuring instrument for recording the flow velocity of a fluid. The ultrasonic measuring instrument has a fluid inlet, a fluid outlet and a flow channel. The flow channel connects the fluid inlet to the fluid outlet, and the flow channel has a measuring area, the measuring area extends linearly in the direction of flow, wherein between the measuring area and the fluid outlet there is arranged a reflective element around which the fluid can flow and through which the ultrasonic signal from the ultrasonic transducer can Reflected into the measurement area or on the contrary, the ultrasonic transducer is arranged on a side wall which delimits the flow section of the flow channel; In the transition region, the distance between the center line of the measurement region extending in the flow direction and the side walls increases in steps or in a continuous manner. Background technique [0002] In ultrasonic measuring...
