Description

Technical Field

[0001] This utility model relates to the field of flow meter technology, specifically a novel gas flow meter. Background Technology

[0002] A gas flow meter is an instrument used to measure the amount of gas in a gas delivery pipeline. It is commonly used in pipeline transportation. A gas flow meter consists of a metering device and a connecting pipe. The metering device is located on the connecting pipe, and most metering devices currently use electronic information displays to display the flow rate intuitively. However, the display part of the current flow meter is exposed, and the screen is easily scratched or dirt adheres to the screen during transportation and use, which affects the reading. The part of the connecting pipe that connects to the gas pipeline is spliced ​​using conventional splicing parts, so the airtightness is generally average. Utility Model Content
