Multiple Level Gauges on Vessel Bridle

Multiple Level Gauges on Vessel Bridle

Multiple Level Gauges on Vessel Bridle

Please help me demystify the reason why sometimes multiple, smaller level gauges will be used instead of one larger gauge for bridles on oilfield vessels. I am aware of the need for multiple gauges if two liquid phases are present, but this is not what I am talking about.

Is there a standard gauge length that is used (ie 24") instead of ordering a "custom size"

Is there concerns over weight or stability?

I know this is sort of a trivial question but I would like to understand why I see so much variability in level gauge applications.


RE: Multiple Level Gauges on Vessel Bridle

Would this be influenced by the level range being monitored in the vessel - shorter LGs' for narrow ranges, and longer LGs' for wider ranges?

RE: Multiple Level Gauges on Vessel Bridle

The main reason is to use "standard" gage lengths and to keep the nozzle structural loads low. Long gages are heavy and have more issues with thermal expansion.

RE: Multiple Level Gauges on Vessel Bridle

Exactly what type of level gage are you referring to?
