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 the metal tube rotor flowmeter is generally 2.5. When the measurement accuracy is required to be higher, the metal rotor flowmeter 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 exhausted; if the liquid contains tiny bubbles flowing, it is easy to accumulate in the sleeve, especially Exhaust regularly. This point is more important for small-caliber instruments, otherwise it will affect the flow indication significantly.7. For instruments with LCD display, avoid direct sunlight as much as possible, so as not to reduce the service life of the LCD.8. Avoid vibration. Including vibration caused by external and internal causes of the pipe network.9. For the dense installation of multiple instruments or the carbon steel process pipeline passing near the instrument, the metal tube rotameter should keep a distance of more than 100mm from the instrument to avoid magnetic field interference.
