Who uses mass flow meters from the following manufacturers
Thread Content
Our company wants to install a mass flow meter; we don’t want to use foreign-made ones as the costs of purchase and maintenance are too high. We’re considering products from Dongfeng Electromechanical – has anyone used them and what are their experiences? ? What’s the word on it? I’d like to recommend some other domestic flowmeters as well, thank you!
Domestic mass flow meters will keep you extremely busy
Is it that serious? I previously chose an E+H 80F flow meter; my flow rate ranges from 0 to 12 T, so I selected a DN40 model. However, E+H advised me to use a DN50 model instead. Is that reasonable?
Who says that the mass flow meters produced by Dongfeng Electromechanical are not good? I’ve used them, and there were no issues with them at all. We use them to weigh and calibrate the polymerization reactors
We’ve used quite a few units here as well; it’s okay! Their service is pretty good! We mainly use them in automatic filling systems.
I’ve used the E+H model; it’s an older version. It’s okay – it hasn’t broken as long as it’s not disturbed. However, there are occasional abnormal fluctuations. The people from the manufacturer didn’t know what the problem was either. We switched to a Dongfeng Electric model last year; it’s easy to operate – one can adjust and reset things on the panel by oneself. There was a problem at first, but when the manufacturer arrived they found that it was due to incorrect wiring on our end. Since then, all 10 units have worked without any issues. Moreover, they came to check and calibrate the instruments during maintenance, so the service was excellent. The E+H model cost 40,000 in bonuses, while this one was resolved for just over 30,000. I’ve also used a domestic brand, but I can’t remember its name; its quality was also quite good!
I use this to measure liquids; I need a tube that’s half the size. Are there any other domestic options available?
The mass flow meters produced by Dongfeng Electromechanical are considered quite good among domestic products; their failure rate is relatively high (compared to Rosemount). However, we have been using them for many years now, and over time their product quality has improved significantly. Their after-sales service is also good – they are available whenever needed, which is quite useful.
Has anyone else used any domestic brand that is relatively better?
It seems that Dongfeng Electric is not bad either
It is recommended that the mass flow meters produced by Dalian Zhonglong Instruments meet quality standards and offer excellent service
