　　3、 Installation:

　　1. When used for gas measurement, it should be ensured that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter to ensure stable operation of the float;

　　2. In order to avoid deformation of the flow meter caused by the pipeline, the flange of the process pipeline must be coaxial and parallel to the flange of the flow meter. The pipeline support should be used to avoid pipeline vibration and reduce the axial load of the flow meter. The control valve in the measurement system should be installed downstream of the flow meter:

　　3. When measuring gas, if the gas is directly discharged into the atmosphere at the outlet of the flowmeter, a valve should be installed at the outlet of the instrument, otherwise a pressure drop will occur at the float, causing data distortion.

　　4. When installing instruments with PTFE lining, do not tighten the flange nuts asymmetrically at will to avoid deformation of the PTEF lining;

　　5. Instruments with LCD displays should avoid direct sunlight on the display as much as possible to avoid reducing the lifespan of the LCD; Instruments powered by lithium batteries should avoid direct sunlight and high temperature environments (≥ 65 ℃) as much as possible to avoid reducing the capacity and lifespan of the lithium battery.
