In-depth discussion on the troublesome and demanding operating conditions of instruments
Thread Content
I believe that every instrumentation professional has encountered rather special chemical process instruments in their work, due to harsh operating conditions and specific requirements for instrument selection. For example, Shenhua encountered special wear-resistant control valves in coal-to-oil production; the issue was gradually resolved only after several modifications to the metal material used. Let’s share the problems we encounter together, so that there may be more sunshine in the lives of those who work with instruments.
Pressure thermometers are relatively common； Nuclear-grade radiation-resistant instruments are quite rare these days ； Nuclear-grade radiation-resistant split-type instruments are extremely rare to see.
What you said is great; I’ve hardly come across such instruments before, and today I’ve learned a lot. May I ask in what fields and devices are these instruments generally used? What are their special features? Are there any manufacturers or brand information you could share? Eager anticipation. :handshake
“\"Nuclear-grade radiation instruments\" – I’m not sure how they are classified. In the petrochemical and coal chemical industries, I have come across many imported nuclear level gauges, nuclear density meters, and other such nuclear instruments; do they fall into this category?
LZ’s thinking is too naive; every harsh operating condition could potentially be the subject of a patent
To be direct, I’m referring to the instrument that, in my opinion, is the most difficult to work with – its selection and application require high standards, making it a real headache. It’s not as big as you say. Thank you for your attention.
Slurry flow meter; concentration around 42%. Due to the properties of the medium, electromagnetic flow meters cannot be used, so reciprocating pumps are required. Over 70 kilograms of pressure. It’s hard to choose. A rectangular flow meter is being used temporarily; I’m not sure how effective it will be.
I’d like to study in detail what device it’s specifically used in; could you help me look into it? If there are any relevant materials available, please let me know. Thank you.
On the gasifier, oil coal slurry is used in place of water coal slurry. The light oil is recycled before transformation.
External clamping ultrasonic waves might be able to solve this problem, provided that the accuracy is somewhat lower, and Doppler sensors would need to be used \"probably\" in order for it to work
Not many products are truly excellent, but this one is indeed useful – it can measure level, interface, and density
