Problems solved by technology

[0004] If there is water in the gas medium or in the pipeline, the structure of the traditional ultrasonic gas meter will cause water to accumulate for a long time after entering the air inlet and cannot be discharged.
Once the surface of the transducer (ultrasonic probe) on the metering module is stained with water, or water enters the air passage of the metering module, it will cause inaccurate metering
[0005] In the traditional structure, the pipes are blocked due to too much accumulated water, and the gas equipment behind the gas meter cannot use gas.
[0006] Under normal circumstances, most of this ultrasonic gas meter is used in gas trade settlement. This situation will also become a way for some low-quality users to maliciously destroy (artificially pour water into it), so as to achieve the purpose of illegal gas theft and cause a lot of damage. Economic losses

Embodiment 1

[0027] Such as Figure 1-2 Shown is a schematic structural diagram of an embodiment of an ultrasonic gas meter, which includes a housing 1 , an air inlet 2 , an air outlet 3 , and a metering module 4 . The air inlet 2 and the air outlet 3 are respectively connected to existing gas pipelines.

[0028] The air inlet 2 and the air outlet 3 are respectively provided at the bottom of the casing 1 . The air inlet 2 is arranged at the bottom of the housing 1, so that the path of gas intake in the pipeline enters the interior of the housing 1 from bottom to top, and the water in the pipeline cannot enter through the air inlet 2 under the action of gravity. The gas outlet 3 is provided at the bottom of the housing 1, so that the gas in the pipeline is discharged from the housing 1 from top to bottom, and the accumulated water in the housing 1 is discharged from the gas outlet 3 under the action of gravity.

Embodiment 2

[0036] Such as Figure 3-4 As shown: the structure of an ultrasonic gas meter includes a housing 1, a metering module 4, the metering module 4 is set in the housing 1, the housing 1 is provided with an air inlet 2 and an air outlet 3, and the air inlet 2 and the outlet Gas ports 3 are respectively connected to existing gas pipelines.

[0037]The air inlet 2 is arranged on the bottom surface of the casing 1, and the air outlet 3 is arranged on the side surface of the casing. The air inlet 2 is arranged at the bottom of the casing, so that the path of gas intake in the pipeline enters the inside of the casing from bottom to top, and the water in the pipeline cannot enter through the air inlet 2 under the action of gravity. The air outlet 3 is provided on the side of the housing, so that the path of the gas in the pipeline from the housing is horizontal, and the accumulated water in the housing is discharged from the air outlet 3 .

Embodiment 3

[0042] Such as Figure 5 As shown, an ultrasonic gas meter includes a housing 1 and a metering module 4, the metering module 4 is arranged in the housing 1, and the housing 1 is provided with an air inlet 2 and an air outlet 3, and an air inlet 2 and an air outlet 3 Connect the existing gas pipelines respectively. The air inlet 2 is arranged on the bottom surface of the casing 1, and the air outlet 3 is arranged on the top of the casing. The air inlet 2 is arranged at the bottom of the casing, so that the path of gas intake in the pipeline enters the inside of the casing from bottom to top, and the water in the pipeline cannot enter through the air inlet 2 under the action of gravity. The air outlet 3 is provided at the top of the housing.

[0043] The metering module 4 is composed of a transducer, and the transducer is composed of one or more sets of ultrasonic probes and air passages. After the gas enters the housing 1 from the air inlet 2, a stable pressure gas chamber is...

Abstract

The invention provides an ultrasonic gas meter, which comprises a shell body and a metering module, wherein the metering module is arranged in the shell body; an air inlet and an air outlet are formedin the shell body; the air outlet end of the metering module is connected with the air outlet; and the air inlet is formed in the bottom surface of the shell body. The structural arrangement of the device breaks the fixed thinking of the structural design of the traditional ultrasonic gas meter, and prevents water in a pipeline from entering the shell body through the air inlet by changing the arrangement position of the air inlet; and the technical problem of accumulated water in the structure of the traditional ultrasonic gas meter is solved from a source, and the problem of inaccurate metering after the surface of an ultrasonic probe on the metering module is wetted is prevented from causing metering failure.

Description

technical field [0001] The invention relates to the field of commercial gas measurement, in particular to an ultrasonic gas meter. Background technique [0002] For traditional ultrasonic gas meters, the air inlet and outlet are at the top of the housing, and there is a metering module inside the housing. In the conventional structure, the air inlet of the housing and the air inlet of the metering module are open. [0003] The big flaws of traditional ultrasonic gas meters are: [0004] If there is water in the gas medium or in the pipeline, the structure of the traditional ultrasonic gas meter will cause water to accumulate for a long time after entering the air inlet and cannot be discharged. Once the surface of the transducer (ultrasonic probe) on the metering module is stained with water, or water enters the air passage of the metering module, inaccurate metering will result. [0005] In the traditional structure, the pipes are blocked due to excessive water accumulat...
