Application of A+QMC balanced flow meters in the fine chemical industry

Thread Content

For acidic and alkaline corrosive liquid media, the A+QMC balanced flow meter features a lined structure and special material loose-flange design to effectively isolate the corrosive medium. All parts in contact with the fluid are made of PTFE or special materials such as Hastelloy, which helps reduce costs while ensuring measurement accuracy. Low investment required, with a shortened time to achieve return on investment. Traditional measurement methods include vortex flow meters without compensation or with partial compensation, or differential pressure flow meters without compensation or with partial compensation provided by a computer system; however, these methods often result in inaccurate measurements and an inability to balance the steam flow. At its core, steam is not a liquid; during transmission through pipelines, changes in temperature or pressure cause changes in the state of the steam itself. As a result, it is difficult to obtain consistent measurement values for the steam flow rate at the upstream and downstream ends of the pipeline. Additionally, vibrations occur during the transmission of steam over long pipelines, which can also affect the actual measurement accuracy of some vortex flowmeters. Solution: The A+QMC balanced flow meter uses orifices with equal Reynolds numbers to minimize eddies and balance the flow field; it also has the capability to throttle and straighten the flow, thereby reducing the required length of straight sections before and after the meter – these sections can now be as short as 2D. At the same time, an AES metering system can be configured to provide real-time, dynamic compensation for both temperature and pressure of the steam, thereby eliminating or reducing energy losses caused by changes in temperature or pressure and improving the accuracy of overall steam energy measurement. The flow measurement accuracy is as high as 0.5%, and the balanced flow meter is not affected by vibrations in the steam pipeline, which could otherwise impact the measurement accuracy. It ensures the stability of long-term measurements, fully meeting the requirements for process control. To address the system errors caused by on-site installation, the process is simplified by allowing assembly and debugging to be carried out on site, which facilitates installation for users, reduces on-site work, minimizes leakage points, and improves measurement accuracy.
