当初次安装和中间维修时，燃气管道中的焊渣等大颗粒杂质会在高速气流带动下

The very first time installation and maintenance center, welding slag Gas Pipeline large foreign particles will impact the flow meter housing and the impeller driven at a high speed gas flow, and the risk of stuck generate mechanical spark wheel, in order to avoid this danger, the flow meter installation instructions required, the filter attached to the tip of the flowmeter, the flowmeter before and after purging conduit prior to installation, the complete removal of dross in the duct, iron, sand and other impurities.

During the initial installation and intermediate maintenance, the welding slag and other impurities in the gas pipeline will impact the casing and impeller of the flowmeter driven by high-speed airflow, and there is a danger of mechanical spark and blocking impeller. To avoid this danger, the installation instructions of the flowmeter require that the front end of the flowmeter be equipped with filters, and the pipes before and after the flowmeter are installed are purged, and the pipe is completely removed. Impurities such as welding slag, iron scrap and sand in the channel.<br>
