Hook Up document

Hi Solmaz,

You're going to have to do better with your post 'coz I can't understand it. It's all of one sentence and I couldn't tell if you misspelled a couple of words or are abbreviating them (like, what's "sth"). Give us more detail about your problem and we'll try to give you our best.

There's a spell checker at the top of the comment editor. It's got an ABC with a check mark. Just now, I used it and it caught my misspelling of "abbreviating". I had spelled it with one "b". Useful tool.

Dear Friend:

Thx for your advice, my problem is this: i don't have sufficient information for drawing hook up document. ESP, impulse line that should be drown for liquid service, i can't understand the need for impulse line. that would be very kind of you if you help me with this matter

Impulse lines are pipes or tubes that connect pressure transmitters to the tank or process piping. Some people call them "pressure sensing lines".

There are several "rules" for using them depending on the application. In fact, the information you are seeking is going to take a long time to type.

One advice I'm going to give you is to get the instrument manuals of the pressure transmitters. These will usually have examples of how to use impulse lines to connect the process to your transmitters.

I'm putting a link to a manual here. I'm not advertising their product but it's the first manual I could find that gives good illustrations, drawings and descriptions.

You could also try googling though it'll take you a long time to go through all the hits.
