Is the FF instrument widely used in China?
Thread Content
How widespread is the use of FF instruments in China? How many times is its price compared to that of ordinary instruments? How many times that of a HART instrument? What parameters or variables can mainly be sent upward? I’m a beginner in instrumentation, so my questions might not be quite appropriate; please forgive me.
FF has a fairly comprehensive set of table functions, but I find its communication speed to be relatively slow. I haven’t had much exposure to it.
Your skill level is even higher than mine; I’ve never even heard of FF instruments before, and I just learned about HART instruments from you. Hehe, I’ll learn from you in the future*
In China, it is still in the trial phase; dedicated transmitters and positioners with FF functionality are required
Fieldbus control systems are known as the fifth generation of control systems and represent the direction of development in the future. Currently, several large petrochemical plants in China have adopted FF instruments, such as Shanghai Seko and Huizhou Ethylene.
:Funk: I’ve also never heard of FF instruments or HART instruments; I’ve only heard of the HART protocol. I’m really sorry about that
China’s largest FF application is at Sinopec in Shanghai; it’s worth taking a look. It has been in use for almost 3 years now. When Emerson leaves, it will take FF with it
I’ve been looking at some FF products recently, and its watch functions are indeed very powerful. All controls are implemented within the table, and the function blocks are also provided by the instrument. However, the communication rate of the FF H1 is only 31.25kbps. But these are all superficial conceptual things; when you go deeper, you don’t know.
:I just read a few web pages introducing smart meters to get a basic understanding of them. As mentioned in the introductions, FF instruments are the most widely used in the petrochemical industry. So I’m looking for some experts on our forum.
A few days ago I checked Emerson’s website; the Rosemount 3051 also comes in several models, with a specific FF version of the 3051 available.
Shanghai Sike used to be the largest FF application site in the world, relying primarily on Emerson’s instruments and systems.
Many sources mention that for Shanghai Sike, Emerson is the manufacturer that primarily promotes FF.
There is another company that uses FF for ethylene production at CNOOC Shell, and their Yokogawa systems require that all instruments support FF communication. Generally, systems in the United States and Japan recommend the FF bus, while European companies recommend the Fieldbus bus.
Let me answer the original poster’s question here. Taking ROSEMOUNT as an example, the 3051CD transmitter with FF bus is about 2,000–3,000 RMB more expensive than those with HART protocol; this is mainly due to the addition of PID processing functions as well as the LINK ACTIVE function
What kind of intelligent system is the FF system? Can it represent the future direction of instrument development? Personally, I think the future development direction of instruments should be toward wireless transmission!
Some people might not be familiar with the term FF; on the other hand, everyone has probably heard of field buses. They are not widely used in China at present, with all communications being digital. There should be books on this topic; people might as well look for them. It seems to be the direction in which things are developing. At present, the price is quite high, so it’s used very little in China.
In the chemical and petrochemical industries, Foundation Fieldbus and Profibus are used, with Emerson and Siemens serving as the leading companies in these areas respectively
