AI Technical Summary

Problems solved by technology

As a result, flow calculations become difficult and error-prone
Due to the large recesses, eddy currents and the formation of air bubbles and cavities can also occur, which negatively affect the measurement results
Furthermore, structural and cost-intensive disadvantages result from the use of multiple ultrasonic transducers

Embodiment Construction

[0048] In FIG. 1 , the reference number 1 shows in a partial cross-sectional view a suitable embodiment of an ultrasonic fluid meter according to the prior art, which has a diagonally arranged ultrasonic measuring path 8 . The ultrasonic fluid meter 1 includes a housing 2 (such as a joint housing) for shielding the ultrasonic fluid meter 1 inside a fluid pipeline system not shown in FIG. 1 , such as a drinking water pipeline.

[0049] Housing 2 comprises an inlet 3 and an outlet 4 . Here, the flow direction of the fluid proceeds from the inlet 3 to the outlet 4 . Inside the housing 2 there is a pair of ultrasonic transducers, which consists of two ultrasonic transducers 6a, 6b. Ultrasonic transducers 6 a , 6 b are each accommodated in an ultrasonic transducer housing 18 . An ultrasonic measuring path 8 for determining the runtime is located between the two ultrasonic transducers 6a, 6b. By arranging the two ultrasonic transducers 6a, 6b on the upper inner wall and the lower...

Abstract

The invention relates to an ultrasonic fluid meter (1) for determining the flow rate and / or volume of a flowing medium, comprising a housing (2), an inlet (3), an outlet (4), an ultrasonic measurementsection (8) comprising at least one ultrasonic transducer (6a), and a second ultrasonic measurement section (11) comprising at least one ultrasonic transducer (9a), wherein the ultrasonic measurements sections (8, 11) are arranged at an angle to one another inside the housing (2) and intersect, the first ultrasonic measurement section (8) and the second ultrasonic measurement section (11) are arranged at an angle to each other when considered in the projection plane of the flow cross-section, and intersect in a common region M.

Description

technical field [0001] The invention relates to an ultrasonic fluid meter for determining the flow and / or volume of a flow medium and a method for determining the flow and / or volume of a flow medium according to the preamble of claim 1 . [0002] Ultrasonic fluid meters are commonly used to determine the consumption of fluid in fluid supply lines. Ultrasonic fluid meters are commonly used to determine the flow, volume or heat of fluids, such as water. Background technique [0003] The most common fields of application of ultrasonic fluid meters are water meters for determining the consumption of drinking water in buildings and households or heat meters for determining the consumed thermal energy. Such ultrasonic fluid meters typically have a housing with an inlet and an outlet. By means of the housing, the ultrasonic fluid meter can be installed in a fluid line network, for example in a drinking water supply. The flow direction of the fluid inside the ultrasonic fluid met...
