Installation
Metal tube rotameter installation
Installed flowmeter should guarantee the entry ≥5DN straight pipe section, export straight pipe section not less than 250mm; if the medium containing ferromagnetic material, magnetic filter should be installed in front of the flowmeter. （see magnetic filter and straight pipe section diamension diagram ）
1.For flow meter installed，ensure the measuring pipe perpendicularity is better than 5 and should be equipped with bypass,easy to maintain and clean and does not affect production..
2.Monitoring and control system in the control valve，should be installed downstream of the flowmeter.For gas measurement，Should ensure the working pressure is not less than 5 times of pressure loss of the flowmeter, to make stable work of the flowmeter.
3.Before install the flowmeter，The pipe should be welding slag purging clean；When installation to remove locking component in the flow meter;when used after installation，Slowly open the control valve，Avoid shock damage flow meter
