C.7.1 Strapping table
The Strapping Table option should be used when the tank shape deviates significantly
from an ideal sphere or cylinder, or when high volume accuracy is required.
The Strapping Table divides the tank into segments. Level values and corresponding
volumes are entered starting at the bottom of the tank. These figures can typically be
obtained from tank drawings or from a certificate provided by the tank manufacturer.
A maximum of 100 strapping points can be entered. For each level value the
corresponding total volume up to the specified level is entered. The volume value is
interpolated if the product surface is between two level values in the table.
C.7.2 Holding and Input registers for volume configuration
Holding registers 4300 to 4732 are used for volume configuration. The different
parameters are given in

Holding Register Description
4300 Bit 1: Volume over Zero. By setting this bit
presentation of negative volumes for product
levels below the Zero level is prevented.
4302 0: None
1: Strapping table
2: Sphere
3: Horizontal cylinder
4: Vertical cylinder
4304 Number of strapping table points used
4306 Distance from zero level to the tank bottom
4308 Tank diameter
4310 Tank length (for horizontal cylinder)
4314 0: linear
1: Quadratic
4316 Strapping table offset. You can use this function
to shift the zero level (empty tank) from the
Datum Plate to the bottom of the tank. The Level
Offset will be added to the measured level and
then used to find the corresponding volume value
in the strapping table. A positive Level Offset
value will increase the displayed volume.
