Sensor Types

A choice of three sounding devices is available, these being a sounding tube, a pressure sensor and a radar sensor. In order to define the geometry of each sounding tube or the position of each of the other two types of sensor, within one or more compartments of the identified set of compartments, it is necessary to select the second of the two Tank Calibration icons and, via the Edit button open the Sensor dialog box. A user can duplicate this overall activity if the vessel is to contain selected compartments each having two or more sounding devices.

If a sounding tube is selected then a series of points established by sets of x, y, z coordinates, defined relative to the mainhull origin, are used in order to describe its geometry. A maximum of twenty sets of coordinates is permitted and these coordinates must be input in ascending order of the z coordinate value. The sounding tube is assumed to be a straight line between each consecutive set of coordinates.

A single set of x, y, z coordinates, defined relative to the mainhull origin, is required to describe the position of a radar or pressure sensor, if such a device is selected by you.

If no sounding device of any type is defined for a particular tank that is listed under the tanks to be calibrated heading, then the program automatically produces tank calibrations by assuming a straight, vertical sounding tube in the centre of the tank. The spacings, that is the increments, of the tank calibration soundings or ullages are defined in a separate input screen.
