Semiautomatic entry of the linearisation table
Example:
In this example, the volume in a tank with a conical outlet should be measured in m
3
.
Prerequisite:
• The tank can be filled. The linearisation characteristic must rise continuously.
• A minimum gap of 0.5 % of the distance between two points must be maintained. Spans for the
"Pressure linearized" option: HYDR. PRESS MAX. – HYDR. PRESS MIN.; TANK CONTENT
MAX. – TANK CONTENT MIN. Spans for the "Height linearized" option: LEVEL MAX – LEVEL
MIN; TANK CONTENT MAX. – TANK CONTENT MIN.
