Mass flow meter
Thread Content
Which manufacturer produces the best mass flow meters with good cost-performance? A comparison between domestic and foreign options: victory:
Undoubtedly, the highest quality option is MICROMOTION’s CMF; followed by E+H and KROHNE. There are also many other brands available.
Mass flow rate: For foreign brands, the main ones are Yokogawa ROTA MASS and E+H, as well as Emerson’s products. Emerson’s products are more expensive than those of the first two brands. Between Yokogawa and E+H, I would choose Yokogawa, as it is reliable to use; once the right model is selected, there are basically no issues. But Yokogawa only offers an accuracy of 0.1%. E+H, on the other hand, provides two options for accuracy: 0.2%, and it’s definitely cheaper with that option
Of course, the mass flow meter should be from Emerson Coriolis – our company uses Coriolis meters; they offer stable performance, high reliability, and high measurement accuracy. Most importantly, they support HART protocol communication, and they are maintenance-free instruments. Secondly, I think it’s E+H, and also Yokogawa.

Try the domestically produced Coriolis mass flow meter – the newly released OVAL ALTI Mass intelligent, high-precision, multi-functional mass flow meter, with an accuracy of up to 0.1 grade, a range ratio of 200:1, a temperature range of -200 to +350°C, a response time as fast as 10 msec (computation cycle), a backlit display, self-diagnosis capabilities, adjustable data settings, and a variety of output signal options, including Hart protocol or RS485.
E+H and Rosemont are good, but they are a bit more expensive
The current mainstream brands include Emerson, E+H, Siemens, Yokogawa, Claron, and so on. Among them, Emerson is the strongest; its CMF model offers the best performance. However, it is the F series that sells best, with a precision of up to 0.1, and at a significantly lower price. Other brands’ products each have their own unique features; those who are interested in discussing this in detail can communicate privately.
It seems that everyone uses them quite a lot, and they are pretty expensive. We’ve only used E+H models; they’ve been in use for over 6 years now, require almost no maintenance, and are quite good. This is just some information for the original poster’s reference.
It’s domestic; Xi’an Dongfeng Electromechanical is quite good – we’ve been using their products. The service is okay.
Flow meter technical specifications: 1. Accuracy, 2. Repeatability, 3. Stability. The technical specifications of some domestic Coriolis mass flowmeters are now close to those of imported products.
