9.4.1 Configuring the level and interface measurement
The level measurement is to measure the position where the displacer is balanced
(immersion point) in the liquid. When the liquid surface level changes, the displacer
continuously follows the position to measure the liquid level. To define the appropriate
level measurement, the following settings are required prior to operation.
The interface measurement can determine the interface between different liquids in a tank
(e.g. water and oil).Up to two different interfaces can be determined within a maximum of
three phases in a tank.
Setting the density of application
Density values for three liquid phases are set as follows prior to delivery.
• Upper density: 0.8 g/ml
• Middle density: 1.00 g/ml
• Lower density: 1.20 g/ml
Change the data to reflect the actual density values. For tanks with only one liquid phase,
set the upper density. For tanks with two or three phases, set middle and bottom densities
as well.
Number of phases Parameters to be set
1 phase Upper density
2 phases Upper/middle density
3 phases Upper/middle/lower density
When performing an interface measurement, the minimum density difference
between phases should be at least 0.100 g/ml.
Setting the density
1. Navigate to: Setup → Upper density , Setup → Middle density and Setup → Lower
density
2. Input the value to Upper, Middle, and Lower densities accordingly.
