Figure 5-3. Plan View — L-Cell and Junction Box Locations (Carbon Steel)
Notes:
1. Spacing is approximate and is based on
spacing L-Cells symmetrically on standard
panel centerlines on bolted vessel.
2. For welded vessel, distribute L-Cells
symmetrically around vessel using spacing
shown above as guideline.
3. For diameters not shown, use the sensor
quantity for the next largest diameter (e.g., for
a 14’ diameter welded vessel, use the number
of sensors for a 15’ diameter vessel, and
distribute symmetrically around vessel). X X

Notes:
• L-Cells A and C are on inside of skirt.
• L-Cells B and D are on outside of skirt.
• For welded vessel, distribute L-Cells symmetrically
around vessel.
• Minimum panel height for L-Cell installation is
6’ (1.8m).
• Junction box is on inside of skirt, 6’ (1.8m)
above foundation.
• Run conduit 1’ (0.3m) below junction box or
near foundation, so it does not interfere with
L-Cell placement.
