Endress+Hauser FMR 231 - Horizontal cylinder; Semi-automatic entry

Horizontal cylinder A linearisation curve for a horizontal cylinder can also be entered manually by using the
table below:
•
Starting at the completely full tank (level/volume = 100%, calculate the % volume
for each level point.
Volume at L % level = Total volume x Volumen %

Note!
If the tank is emptied step-by-step, the following must be noted:
•
The number of points must determined before starting.
•
The first table no. = (30 – no. of points)
•
The entries in V2H1 must be made in descending order (last entry = 1).
