Precautions

1. When the air flow meter is inserted into the straight pipe section, the direction is adjusted correctly;

2. In order to ensure safety, a reliable grounding wire should be connected to the detector at the site;

3. All units of measurement should be converted to the unit of measurement required by the standard, which is convenient for the judgment level.
