The glass rotor flowmeter is characterized by its resistance to pressure, durability and accurate measurement. It can detect the flow of acids (excluding hydrofluoric acid), oxidants, alkalis and other corrosive gases or liquids. It is suitable for pharmaceutical, chemical, sewage treatment and papermaking. industry. The glass rotor flowmeter consists of a cone-shaped glass tube that expands from bottom to top and a float that moves up and down with the fluid flow rate. Here are the advantages of the glass rotor flowmeter produced by the company:
1. Straight pipe section requires low glass rotor flowmeter because the flow field is stable, and the pressure recovery speed is twice as fast as that of the orifice plate, which greatly shortens the requirements for the straight pipe section. The front and rear straight pipe sections are generally 1D before the 3D, and the minimum can be less than 0.5D. This saves a lot of straight pipe sections, especially the special expensive material pipes.
2. Good reproducibility and high linearity The product has a symmetrical porous structure, which can balance the flow field, reduce eddy current, signal and vibration noise, improve the stability of the flow field, and improve the linearity of the orifice plate by 5 to 10 Times, repeatability increased by 54% to 0.15%, from its comprehensive performance, balance flow meter belongs to the ranks of high-grade flow meters.
5:1 turndown ratio, linearity up to ±0.3%
7:1 turndown ratio, linearity up to ±0.5%
10:1 turndown ratio, linearity up to ±1.0%
3. Reduced permanent pressure loss The porous symmetric balance design reduces the formation of turbulent shear forces and eddy currents and reduces the loss of kinetic energy. In the same measurement conditions, it reduces the permanent pressure by 2.5 times compared to the orifice plate. The loss, which saves a considerable amount of operating energy costs, is an energy-saving instrument that is worth a lot of promotion.
4. The long-term stability of the product is good because the turbulent shear force of the product is significantly reduced, the direct friction between the medium and the throttling element is greatly reduced, the β value remains unchanged for a long time, and the entire instrument has no movable parts. Therefore, Long-term stability.
5, dirt-resistant and not easy to block the symmetrical symmetrical design of the porous, reducing the formation of turbulent shear force and eddy currents, thereby greatly reducing the formation of stagnant dead zone, ensuring that dirty media through a plurality of holes, reducing the fluid hole Blocked opportunities.
6. It can directly replace the orifice glass rotor flow meter and the orifice plate with the same use method and shape, so it can be directly replaced, no need to change the relevant instrument and any changes in the piping, it is very suitable for the whole plant energy measurement transformation will be hole The board is changed to a balanced flow meter.
7. Wide flow measurement range According to the test results, we learned that the performance of the glass rotameter can make its flow rate from the minimum to the speed of sound, its minimum Reynolds number can be less than 200, the maximum Reynolds number is greater than 107, and the beta value can be selected as 0.25 ~0.90.
8, can measure the complex working conditions of the media due to the product's special structural design, it has a special performance. It can carry out gas-liquid two-phase, various low-temperature gases (such as LNG, liquid hydrogen, liquid oxygen, liquid argon, liquefied ethylene, liquefied petroleum gas, etc.), various mixed gases (such as gas, gas, biogas, etc.), and gas liquid. Two-phase media (such as moisture), slurry, multi-phase flow, vibration flow, electromagnetic interference media, and bi-directional flow (since the balance flowmeter is completely symmetrical).
9. Measurable high-temperature and high-pressure medium glass rotor flowmeters, like throttling devices such as orifice plates, work at temperature and pressure depending on the material and grade of the pipes and flanges. The working temperature can reach 850°C and the working pressure can reach 42MPa.
