The metal tube rotor flowmeter has the characteristics of simple structure, reliable operation, wide application range, accurate measurement, and easy installation. It is resistant to high temperature and high pressure. The metal tube rotor flowmeter has ordinary and anti-corrosion types, which are divided into on-site indication type and electric remote transmission type, ordinary flow sensor, instrument material (1Cr18Ni9Ti), and anti-corrosion type (1Cr18Ni9Ti) lined with PTEF.

Installation:

1. The flowmeter must be installed vertically, and the measured fluid passes through the flowmeter from bottom to top. The inlet and outlet must have a straight pipe section of 5 times the diameter of the instrument. For newly installed pipelines, the pipeline should be flushed clean before installing the flowmeter.

2. For the convenience of maintenance and replacement of flow meters, a bypass pipeline needs to be connected during instrument installation.

3. Valves should be installed upstream of the flowmeter, and flow regulating valves should be installed downstream at 5-10 times the instrument diameter. For small-diameter instruments, a filter should be installed upstream. If the measured medium contains magnetic substances, a magnetic filter should be installed before the flowmeter.

4. When the measured medium is dirty, the tube and float should be cleaned in a timely manner.

5. The measurement accuracy of a metal tube rotor flowmeter is generally 2.5 levels. When high measurement accuracy is required, it is not advisable to choose a metal rotor flowmeter.

6. For angular metal float flow meters with import and export not in a straight line, when used for liquids, pay attention to whether there is any residual air in the extended sleeve of the external float displacement, and it must be drained completely; If the liquid contains tiny bubbles that are prone to accumulate inside the casing during flow, it is even more important to exhaust them regularly. This is more important for small caliber instruments, otherwise it will significantly affect the flow indication.

7. Instruments with LCD displays should avoid direct sunlight as much as possible to avoid reducing the lifespan of the LCD

8. Avoid vibration. Including vibrations caused by external and internal factors of the pipeline network

9. When multiple instruments are densely installed or carbon steel process pipelines pass near the instruments, the metal tube rotor flowmeter should maintain a distance of at least 100mm from the instruments to avoid magnetic field interference.

The metal tube rotor flowmeter adopts a variable area measurement principle and is suitable for measuring liquids and gases. All metal structure, including indicator type, electric remote transmission type, corrosion-resistant type, high-voltage type, jacket type, and explosion-proof type.

It has standard analog signal output and on-site indication of 0-10mA and 4-20mA. Accumulation, digital communication, on-site modification of measurement parameters, different power supply functions, with magnetic filters and specifications.

Metal tube rotor flow meters are widely used in industries such as petroleum, chemical, power generation, pharmaceuticals, food, and water treatment. During the flow measurement process under complex, harsh environmental conditions, and various media conditions.
