Horizontal Drum Tap Locations for Level Indicators

Horizontal Drum Tap Locations for Level Indicators

Horizontal Drum Tap Locations for Level Indicators

Hi All,

My department is going through some spec reviews and something brought up a discussion about our horizontal Drum level tap locations and how we arrived at the standards that we have now.
For reference, we set a standard that the upper level tap shall be 4" above HHWL and the lower tap is 1" below LLWL. Of course this may change on a project-to-project basis but that's the "norm" for us.

So I was wondering if there's a specific standard that lays out a requirement for these taps.


RE: Horizontal Drum Tap Locations for Level Indicators

Not sure for a specific standard for the level taps setup. IMO, it's more related to the process design and/or the specific instrument requirements.
