　　4、 Installation precautions:

　　1. The metal tube float flowmeter must be installed on a vibration free pipeline. The fluid flows through the flowmeter from bottom to top, and the verticality is better than 2 °. When installed horizontally, the horizontal angle is better than 2 °;

　　2. For the convenience of maintenance, replacement of flow meters, and cleaning of measuring pipelines, metal tube float flow meters installed on process pipelines should be equipped with bypass pipelines and bypass valves;

　　3. The inlet of LZ metal tube rotor flowmeter should have a straight pipe section with a length of more than 5 times the pipe diameter, and the outlet should have a straight pipe section of 250mm;

　　4. If the medium contains ferromagnetic substances, a magnetic filter should be installed; If the medium contains solid impurities, it should be considered to install a filter between the valve and the straight pipe section;

　　5. 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.
