The "level" menu
25
• horizontal cylinder
4)
• sphere
In these linearization types the measured level is convertet to the volume in a horizontal cylinder
or a spherical tank.
The following additional parameters have to be specified:
– the unit of the linearized value, e.g. kg, m
3
, ft
3
, ... ("customer unit")
– the diameter (D) of the tank ("diameter")
– the maximum capacity (a) of the tank, measured in the customer unit ("maximum scale").
• angled bottom (A)
• pyramid bottom (B)
• conical bottom (B)
In these linearisation modes the measured level is converted to the volume in the respective type
of vessel.
The following additional parameters have to be specified:
– the unit for the linearized value, e.g. kg, m
3
, ft
3
, ... ("customer unit")
– the intermediate height H according to the diagram ("intermediate height")
– the maximum capacity (a) of the tank, measured in the customer unit ("maximum scale").
4) This option is only valid for horizontal cylinders without dome ceiling. For tanks with dome ceiling ToF Tool or FieldCare can be used to calculate a linearisation
table and to upload it into the instrument.
