Operating Instructions

Step 2 – Application
1. Click on Step 2.
2. Select the application type (Level/vessel, Level/stillpipe, Level/bypass pipe, Volume/vessel,
Volume/stillpipe, or Volume/bypass pipe) and the material (Liquid or Low dielectric liquid).
3. Click on Apply.
Step 3 – Vessel Shape
1. Click on Step 3.
2. Select a predefined vessel shape. To describe a more complex shape see Linearization
(Page 88).
3. Click on Apply.
Step 4 – Ranges
1. Click on Step 4.
2. Change units if desired (in meters by default).
3. Set High and Low Calibration points.
4. To convert the reading from level to volume enter a value for Maximum Volume.
5. If a vessel shape with parabolic ends has been selected, set dimensions A and L.
6. Click on Apply.
Step 5 – Summary
Check parameter settings, and click on Cancel to abort, or Apply to transfer values to the device.
Linearization
You can use the linearization feature to define a more complex vessel shape and enter up to
32 level breakpoints where the corresponding volume is known. The values corresponding to
100% and 0% levels must be entered. The breakpoints can be ordered from top to bottom, or
the reverse.
Using linearization via the Quick Start wizard
Navigate to Configure/Setup > Wizard > Quick Start.
In Step 1 – Identification, make any desired modifications and click on Apply.
In Step 2 – Application, select a level application and liquid as a material.
In Step 3 – Vessel Shape, choose the vessel shape option Linearization Table.
In Step 4 – Ranges, enter a value for maximum volume.
