Steam Line Pressure tap seal pot installation

On top of the pipe with an isolation syphine to prevent "live" steam from hitting the transmitter.

Mike

The setup is tap off the top of the steam line. Were should the seal pot be installed ?

Along side the steam line or above or below the steam line? And were should the

transmitter be located? Thank You

Hello Guest,

you seem to have a pretty good answer from the expert "Boilerguy". But here is a few other choices:

Hello mike,

Great references. Thanks for sharing.

My pleasure my friend! Really your name says it all!

hi all!!

I would like to help me with a problem I'm having problems with a boiler level sensor (differential pressure)
when the boiler delivers less than 4000 kg / h of steam sensor readings are correct
when given a little over 4000kg / h sensor readings are an inch above and when delivery 11000 Kg / h sensor readings are about 3 inches above
reviewing the plans, I realized that the reference HP (bottom of the boiler) the sensor is connected in the wrong place next to the right place but do not think this is the real problem I think the real problem is that I did not put a " seal pot" in the reference leg LP (top of the boiler) this may be the cause of my problems?
influence too much the "seal pot?
which is exactly what happens inside the boiler?
to deliver steam to a large amount this makes the pressure at the top of the boiler to drop so that readings vary according to the flow of steam?
in a few days the boiler stopped to make the necessary changes and make sure I get it right this time
thanks for any help best regards
excuse my English I understand it ............. but my writing is disastrous

Dear All

what about the orientation of the seal pot any preference.

Regards

Dear All

for the seal pot it is necessary to use vent plug or blind plug.

any advise pleaseee.

Regards

I've only seen plugs, like the hex plug below used for sealing the top port after filling the pot and impulse piping.

Although a vent valve would allow an air purge on start-up, I'd have to think about a safe way to manage it. I'm sure the style with a vent tube or barb (on the right, below) would be essential for conducting the vented air/fluid/steam safely.

Those kinds of high pressure vent valves are routinely used on DP transmitters, I can't see a down side. Might have to use a pressure rated reducer bushing.

Maybe a steamboiler guy has another opinion . . .
