A level offset must be given as the displacer is now immersed for half of
the volume in water. On product level the displacer is immersed less.
The difference between both immersion depths must be given in the
[Primary value offset] of the primary value of the water or interface2 level.
(refer to Figure 7-41 (value L3) and to Appendix B for detailed displacer
information)
Example:
1. Immersion depth on product level surface:
Displaced volume:
([Displacer weight] - Setpoint1) / ρ
product
= 15/0.9 = 16.67
cm
3
Volume in cylindrical part: 16.67 - 3.2 = 13.47 cm
3
Immersion of cylindrical part: 13.47/
πr
2
= 13.47/(π*2.25

) = 0.85 cm
= 8.5 mm
Immersion depth on product: 8.5 + 6 = 14.5 mm
2. Separation line product / water:
water volume in cylindrical part:
½[Displacer volume] - 3.2 = 52.5 - 3.2 = 49.3 cm
3
Water height in cylindrical part: 49.3/πr
2
= 49.3/(π x 2.25
2
) =
3.1 cm
= 31 mm
Separation line product / water: 31 + 6 = 37 mm (from lower
end of displacer)
Hence, the [Primary value offset] of the water level PV becomes:
37 - 14.5 = 22.5 [mm] = 0.00225 [m]

Description
[Setpoint 3] [Setpoint 3]
(Water level)
Set point for the product / water interface
measurement.
[Primary value offset]
(Water level)
- General level offset.
Used for level offset between interface 1 immersion
depth (where the gauge is calibrated) and the
product / water interface immersion depth.
