 Installation Position of Metal Tube Rotameter
 
1. The flowmeter must be installed vertically. The measured fluid passes through the flowmeter from bottom to top.
   The inlet and outlet are guaranteed to have a straight pipe section of 5 times the diameter of the meter. 
   For the newly installed pipeline, the pipeline should be flushed before the flowmeter is installed.
2. In order to facilitate the maintenance and replacement of the flow meter, the bypass pipeline should be 
   connected when the meter is installed.
3. A valve should be installed upstream of the flowmeter, and a flow regulating valve should be installed downstream 
   of 5 to 10 times the diameter of the meter. For small-caliber instruments, a filter should be installed upstream.
   If the measured medium contains magnetic substances, a magnetic filter should be installed in front of the flowmeter.
4. When the measured medium is dirty, the pipe and float should be cleaned in time.
5. The measurement accuracy of metal tube rotameter is generally 2.5. When the measurement accuracy is required to 
   be high, metal rotameter is not suitable.
6. Angle metal float flowmeters whose inlet and outlet are not in a straight line. When used in liquids, 
    pay attention to whether there is any residual air in the extended sleeve of the outer float displacement. 
    It must be drained; if the liquid contains tiny bubbles flowing, it is easy to accumulate in the sleeve, 
    especially Exhaust regularly. This is more important for small-caliber instruments, otherwise it will affect the flow rate indication significantly.
7. The instrument with liquid crystal display should avoid direct sunlight as far as possible, so as not to reduce the service life of liquid crystal
8. Avoid vibration. Including vibration caused by external and internal causes of the pipe network
9. For metal tube rotameters, when multiple instruments are installed densely or carbon steel process pipelines pass near the instrument,
   keep a distance of more than 100mm from the instrument to avoid magnetic interference.
