Install an adapter piece from 2"flange to 3"or 4" flange. Buy a new transmitter with direct or remote seal for the new flange with a special oil for your temperature specifications. A smaller flange size it's not a solution. If your problem is only the sludge draining, I recommend this easiest solution. I'm also using the radar and I believe the DP transmitter is a very simple and reliable solution.

I want to ask about the reason of increase flange size, i can use 2" existing flange and order a new transmitter with the suitable liquid.Are Remote seal accurcy with sludge with be greater than Dp transmitter as i need to drain it daily or radar will the greatest accuracy.

If we use non- contact radar in my case (shell and tube)without using bridle,the readings will be accurate or the bundle inside exchanger will affect the readings....

Hi hashem ali,

Do you have a way to access the top of the heat exchanger?  Because you don’t have a bridle, to consider a radar solution you will need a way to install the device on top of the heat exchanger that has a clear path to fluid.  

To better answer your questions, I need some very specific information:

Please provide your mechanical drawing to (nathan.stokes@Emerson.com) as I did not see it get posted here.

Other application data I would need to evaluate your application would be:

• Process temperature min and max (operating)
• Ambient temperature min and max at your location
• Process pressure min and max (operating)
• Specific gravity or density of the fluid whose level you want to measure
• Tap to tap distance

You are currently using a 2” 300# flange correct? 

Would you be concerned about build up inside of the flange connection?  You could consider an extended seal design that has a extension into the flange so that the diaphragm is flush with the inner vessel wall.  This will eliminate any potential for plugging.

The others comments about flange size are valid.  This is because the diameter of a remote diaphragm seal has a big impact on the performace of the unit.  The larger the diameter of the seal, the better overall performance you can get from a system.  A 2” 300# connection is very common remote seal size and you can get good performance from it.  By providing the information above, I can calculate what the performance would be in your application and if a traditional system with capillary would be best or if Electronic Remote Sensors would be best.

If you have the ability to add a radar measurement to the top of the heat exchanger, we can also provide you with information about that type of solution so you can evaluate the tradeoffs between a radar solution and a differential pressure based solution and what will be best for your application.

Dear nathan,
good day,
firstly,listed under-here all the parameter required:
1-min process temp.=229 F
max process temp.=425 F
2-ambient temp. min=9 C
ambient temp. max=45 C
3-process pressure min=88.3 psig
process pressure max=185 psig
4-density of condensate=0.7848 g/cm3 at 288 K
5-Tap to tap distance(flange to flange)=130cm
6-URV=-33 inH2O
LRV=-63 inH2O
if you need any further data don't hesitate to contact me,
can you please also evaluate the tradeoffs between a radar solution and a differential pressure based solution?
