Guided wave radar measures both the level and interface level in separators, and settling and condensate tanks.
The cost for wiring and installation is reduced because there is one tank penetration and a single pair of wires.
There are some basic conditions which must be met in interface measurements:
• The lower dielectric fluid must be on top
• The two liquids must have a dielectric difference of at least 6
• The upper layer dielectric must be known (in-field determination is possible)
