Description

Technical Field

[0001] The utility model relates to the technical field of meters, and in particular to a natural gas metering device. Background Art

[0002] Natural gas metering devices are used to accurately measure the total amount of natural gas flowing through pipelines for billing, control, and monitoring purposes. They are widely used in urban gas pipeline networks and in natural gas supply systems for industrial, commercial, and residential users. Natural gas metering devices are typically installed on walls or building surfaces and require special care during use to prevent damage from impacts and other accidents that could affect metering accuracy.

[0003] Patent publication number CN115824341A discloses a natural gas metering device comprising a natural gas meter, a protective housing, a first protective assembly, and a second protective assembly. The natural gas meter is mounted within the protective housing. A natural gas inlet pipe and a natural gas outlet pipe are fixedly connected to the meter at each end. These pipes are connected to a natural gas pipeline. The first protective assembly comprises a first protective plate and a curved housing. The first protective plate and the curved housing are fixedly connected and located on the outside and inside of the protective housing, respectively. The natural gas inlet pipe and the natural gas outlet pipe extend through the first protective plate and the curved housing.
