What is the measurement accuracy of domestic mass flow meters? Recommended manufacturers of Coriolis mass flow meters
Thread Content
With massive investments in the chemical industry, how has the quality of domestic instruments improved? I checked the forum posts on measurement accuracy; they all mentioned products imported from abroad. The only domestically produced one seems to have been linked to overseas gambling websites. What are the measurement accuracy and localization progress of Coriolis mass flowmeters? Are domestic leading companies following up on such advanced flowmeters? The market should have considerable demand.
Chemical companies are generally conservative and not very sensitive to costs; few people would take such a risk. Chuan Yi offers mass flow meters; judging from Chuan Yi’s reputation, they shouldn’t be too bad.
Beijing Shouke, Xi’an Dongfeng Electromechanical
Beijing Shouke, Xi’an Dongfeng Electromechanical, Qingdao Aowei – there is still a difference in high precision between domestic and imported products, but the difference in low precision is minimal
Shanghai Yino and Shanxi Taihang both have them, and the quality is good too{:9002:}
I used Shanghai Yino 15 years ago; it wasn’t that great. Back then it was probably just newly released and still had some flaws. I’m not sure how it is now； Dongfeng Electromechanical is okay, it’s just a bit large in size
I just bought three Dongfeng electric fans; they are indeed a bit large in size
If quality flowmeters are to be competitive with imported brands, it is necessary to find good brands among the technology developers; Xi’an Dongfeng Electromechanical, Shanghai Yino, as well as Qingdao Aowei, all follow similar technical approaches. The products they produce are generally larger in size, as greater bends make it easier for vibrations to occur, which in turn makes it harder to create sensors that can provide stable measurements. For things like the eh slightly curved tubes, it’s relatively more difficult to initiate vibration in the Cologne straight tubes, but they do a great job; their technical specifications are also superior. Currently, in China, one could consider the quality mass flowmeters produced by the Zhejiang Tianxin brand.
For any domestically produced instrument, one needs to determine where its technical origins lie Most of the current mass flow meter brands use domestic technology; very few rely on technologies from foreign manufacturers. You might want to take a look at the Zhejiang Tianxin brand.
I think Xiner in Nanjing is worth giving a try!
