8. Enter the Hybrid Min Level.
This value specifies the lowest product level at which TankMaster calculates the
Observed Density. Normally, the accuracy of pressure sensors is reduced at low
pressures, i.e. at product levels close to the sensor membrane. Therefore, you can
specify a limit below which the density calculation is “frozen”. For example, if
Hybrid Min Level is equal to 2.0 meter, the Rosemount Tank Gauging system will
present a fixed density value for product levels below 2.0 meter.
Note
Specify the actual product level and not the distance between the pressure sensor
and the product surface.
9. Enter the P3 Sensor Position, i.e. the position of the center of the Vapor Pressure
sensor membrane measured from the tank Zero Level/Datum Plate.
10. Click the OK button to save the Hybrid Density configuration.
C.7 Volume configuration
To configure the Rosemount 2410 Tank Hub for volume calculations, choose one of the
standard tank shapes, or the strapping table option, see Table C-4. Select None if volume
calculation is not used. For the standard tanks, a Volume Offset parameter can be
specified to be used for a non-zero volume that corresponds to the Zero Level. This may be
useful, for example, if you like to include the product volume below the zero level.
Volume calculation is performed by using a predefined tank shape or a strapping table.
Note
For application software version 1.B5 and older, tank volume calculation has to be enabled
in Holding Register 6136.
One of the following standard tank shapes can be chosen:
• Sphere
• Horizontal Cylinder
• Vertical Cylinder
• The following parameters must be entered for a standard tank shape:
• Tank diameter
• Tank length (for horizontal cylinder)
• Volume Offset (use this parameter if you like to include product volume below the zero
level)
• For application software version 1.B5 and older, tank volume calculation has to be
enabled by setting bit 31 "TANK_VOLUME" in Holding Register 6136
