Yeah, I would just get sealed leg capillaries and be done with it. Tell them the minimum temp you get to. I have installed this for -50C aps using Rosemount.
If your heart is set on wet legs (uggg) glycol gets pretty thick in the cold. you might need to go from a 60/40 glycol (assuming that...
the laser will not likely work...has not in my experience.
The scale might, but I am guessing there will be piping that will scew that measurement.
I would consider a Nuclear gauge. I have had to use this in similar applications in the past.
i would contact rosemount. in similar applications i have used necked / standoff manifolds. I was shocked at how much research has been put into temperature rating and management in the past few years when i attended a seminar a few months back.
I have actually installed rosemount...
Think of it like your furnace. You may set a stat at 22C, but it is going to stray up and down a couple degrees (say 19-25C). Not a big deal in the house. If you use a VFD on the furnace you will maintain that 22C. View the VFD as said control valve. It maintains Set-Point, as opposed to...

radar, ensure it is low frequency, not high, when dealing with froth / foam. Guided would be much better.
Don't rule out contacting systems. There are many great vendors, one of which is http://www.ktekcorp.com. Their Megnoresistive are pretty reliable. A capacitive probe would work well...
I would look to hiring a 3rd party commissioning crew. That generally works best. The installer is more conscious of maintenance friendly installations because they know another company will be going through their work before it is "turned over." 3rd party commissioning has always worked best...
There are fields that require an ESD after any schedule change even. So in a gas well you would have to have one off the well head (and potentially a down hole ESD as well), at the separator, at the line heater, and prior to the pipeline.
JLSeagull - a "flow element" is a very broad statement. anyything that measures flow has a "flow element." An orifice plate is a flow element, as is a hot wire, as is the vortex shredding bar, as is a coriolis tube, etc etc etc.
What model was the Intek meter? I am familiar with some of...
not hot wire in the tradition handheld sense you refer to
Kayden makes a model:

so does kobold (KAL-K, KAL-A, KAL-L, etc models)
Sage makes them
there are piles of makes and models

I have seen several installations using a DP setup.
You can do DP across the fan, and that is generally not too bad. This won't really work for you as you are using 1 fan and have 3 lines (unless of course that on fan is a primary and then each line has a booster). You can also do this if...
Ahh, I see...he is worried about choked flow causing critical pressure due to the increased velocity via the fixed u/s pressure and a the potential for a higher dp at points. This reagent must have a lower critical pressure or something....I dont really ever run into the issue, but it makes...
I have used these literally hundred of times on compressors, and never had an issue. the downside is that response time is hampered greatly. I have also used them on several pumps.
good point roydm. I have never really had issues, and in a 6" duct, I don't think there would be. Another option is a flow vein, like the Flowtect V4. These are however very finicky. I would stay away from them, but it is an option. There is one more...I am for some reason drawing a blank...
