Tank Calibration Folder Dialog - Default Data

Tank Calibration Folder Dialog - Default Data Sheet.

This tab sheet enables you to set various defaults that, unless subsequently over-ridden for a specified compartment, establishes the manner in which the calibration is to be undertaken and the data produced for the group of tanks as a whole.

Setting values for extra trims and heels enables you to allow for a vessel that frequently operates away from a level keel condition. The range of densities would be set to be compatible with the operational purposes of the particular group of compartments that was identified on the Compartments tab sheet.

The effect of defining the calculation and output steps is to enable you to allow for the frequently complex geometric shapes of tanks, particularly for levels in their lower and upper regions and where accurate contents data will be required by an operator. The increment defines the vertical calibration steps, in meters or feet, starting from the base of the compartment up to the specified level of fill expressed in percentage of total tank capacity terms. you can add and delete steps within the two tables, however he must ensure that the percentage increments are always in a sequentially increasing direction from a small value at the top of each table, that is near the bottom of the tank, to a full or close to being full value at the bottom of the table, that is near to the top of the tank.

The sensor type provides a drop-down menu enabling you to make a single selection from three standard types, namely sounding tube, pressure pad, and radar sensor, with sounding tube being the default type.

Further output options provided are:

• Separate Table for Each Trim,

• Display Geometry, which if selected will result in a 3D diagram of the compartment being included in the calibration report, and

• If you select the Edit Table button in this tab sheet Calc presents you with another dialog box labelled Table Format.

  

  Default Data Sheet - Table Format.

This dialog enables you to directly select from the full list of properties that Calc can calculate, those specific properties that you wish to be produced for the particular report. This enables Calc to set up the output table format.

If you select the Edit Graph button in this tab sheet Calc presents you with another dialog box labelled Table Calibration Graph Options.

Tank Calibration Graph Options

This dialog enables you to specify the curves to be plotted and other data associated with the tank calibration diagram.

There are three options for plotting the VCG against sensor measurement, as well as volume:

• No VCG

• Actual VCG

• Actual and virtual VCG

Other options are as follows:

• Plot Longitudinal Centre of Gravity (LCG) against sensor measurement

• Plot Free Surface Moment (IT) against sensor measurement

• Vertical Sensor Axis - checking this option causes the sensor measurement scale to be vertical on the left-hand side of the graph. The dependent axes will then be drawn horizontally at the bottom of the diagram.

By default the text of the sensor measurement scale is Sensor Measurement. Any text given by you in the Text for Sensor Axis edit box, will replace this default text.
