　　3、 Installation requirements:

　　Before installing the flowmeter, all packaging should be disassembled, the components that fix the float during transportation should be removed, and any transportation damage should be checked.

　　Before installing the flowmeter onto the process pipeline, the pipeline should be purged to clean the welding slag inside the pipeline and prevent impurities from blocking the instrument and affecting normal use.

　　To ensure measurement accuracy, it is recommended to install a 5DN inlet straight pipe section upstream of the flowmeter and a 250mm outlet straight pipe section downstream.

　　4. Flow meters can be installed vertically or horizontally. If installed vertically, the verticality should be ensured to be better than 1%. If installed horizontally, both the verticality and levelness should be ensured to be better than 1%.

　　If the medium contains solid impurities, a filter should be installed between the valve and the straight pipe section; If the medium contains ferromagnetic substances, a magnetic filter should be installed upstream of the flowmeter.

　　Due to the installation of a magnetic remote transmission system in the tube float flowmeter, it is necessary to ensure that the magnetic fields generated by other surrounding equipment do not affect the measurement results.
