Regarding the selection of mass flow meters
Thread Content
High-pressure gas at 30 MPa, with a temperature of over 100 degrees. Considering accuracy, a mass flow meter is the appropriate choice. Among those available currently are E+H, Kolon, and Yokogawa; after reviewing their technical specifications, it seems that their products are similar, but the prices vary significantly. I’m not sure which one to choose. From the perspective of long-term stability and reliability, which brand do you recommend? Everyone talks well of Emerson, but its price is the highest. I’d like to hear everyone’s opinions!!
I’ll still choose Emerson; from the perspective of actual production use, Emerson’s products are indeed superior
From the perspective of practical production applications and future convenience, imported options include Rosemont, while domestic options are Xi’an Dongfeng Electromechanical. Recently, domestic products have also become quite good, with excellent quality and performance. It is recommended to support domestic products.
So, how about E+H and Cologne? What our boss wants is to choose between E+H and Cologne; Emerson is just too expensive, and its sales staff are also extremely arrogant
E+H is also fine; are domestic options not considered?
Let’s not consider domestic products; our equipment is meant for export, and foreigners have high standards – it would be troublesome if something goes wrong
Then the E+H model will do; Rosemount’s offers poor service. :L
Since Emerson’s option isn’t being considered, cloning will do; it offers high reliability.
I just talked to the boss about it. He simply decided to go with E+H. Heh, I’m not sure if this decision by the boss is correct. Thanks to everyone for their discussions
The quality of E+H is good, so there’s no need to worry about Emerson’s salesperson. . Failure!
You can try choosing Yokogawa’s, as it offers good value for money. This is because the zero-point stability of Yokogawa’s mass flowmeters is better than that of Micro Motion, and its accuracy level is 0.1%, which is the highest available among Micro Motion’s products. However, it entered the Chinese market later, so its market share is relatively low.
The situation in Cologne is said to not be very good.
The guy on the 12th floor is an expert; I’d like to learn from him*. It seems like your company is quite strong, able to use a large number of Emerson mass flow meters
For E+H, I don’t think Rossmont’s after-sales service is as bad as what was said above~
The key question is: what is the purpose of using a mass flow meter? If it is for trade settlement, choose the best option, as the losses caused by even minor deviations or failures in trading can be dozens or hundreds of times greater than the investment in the flow meter. Of course, the exception is when you have sufficient means and methods to replace it! This post was last edited by zxg.wylton on 2009-2-6 09:57.]
