AK-LZ series metal tube rotameter has simple structure, reliable operation, high accuracy and wide application range. Compared with glass rotameters, they can withstand higher pressures. LZ series flowmeters have local indication, remote transmission, limit switch alarm, corrosion resistance, jacket type, damping type and explosion-proof and other varieties. It is widely used in the measurement and automatic control of liquid and gas flow in sectors such as defense, chemical, petroleum, metallurgy, electric power, environmental protection, medicine, and light industry.
When installing and using metal rotor flowmeters, pay special attention to the following:
1, metal rotor flowmeter must be installed vertically, the measured fluid flows through the funnel from the bottom up, import and export to ensure that there are 5 times the diameter of the straight pipe section, for the new installation of the pipeline, the pipeline should be cleaned before installation.
2, in the upstream of the flowmeter should install the valve, in the downstream 5 to 10 times the diameter of the instrument installed flow control valve. For small-diameter instruments, filters should be installed upstream. If the measured medium contains magnetic substances, magnetic filters should be installed in front of the flowmeter.
3, in order to facilitate the inspection and replacement of the flowmeter, when the instrument is installed, it is necessary to connect the bypass line.
4. The metal rotor flowmeter needs regular cleaning, especially when the measured medium is dirty, the tube and float should be cleaned in time. This keeps long-term stable measurements.
5, metal pipe rotameter measurement accuracy is generally 2.5, when the required measurement accuracy is high, it should not choose the metal tube rotameter.
6. Import and export not in the angle of the angle of the metal floater flow meter, when used in liquids, pay attention to whether the residual air in the outer casing of the float float displacement must be drained; if the liquid contains tiny bubbles, the liquid can easily accumulate in the casing, it should be Schedule exhaust. This is more important for small-caliber instruments, otherwise it will affect the flow indication obviously.
