Linearisation for tanks
with conical outlet
You require a linearisation table, H/V or
H/G, max. 30 pairs in increasing order
• Level H in %, m or ft
• Volume V or weight G in customer units.

Note!
• First pair ~ 0 % level, in %, m, ft.
last pair ~ 100 % level, in %, m, ft.
• On error E602 or E604, correct table.
Re-activate linearisation in V2H0.
After linearisation
• Volume/weight is displayed at V0H0
• Level is displayed at V0H9
Next step
…Set analogue output and relays in volume
or weight units, p. 30…33.
