5. Select the Calibration option from the Advanced Setup menu.
The tank calibration distances are defined as illustrated on
the next page.
1 Set the Distance Offset (G).
The Distance Offset is defined as the distance between the upper
reference point and the flange
( the flange is referred to as the Tank
Radar Pro Reference Point)
. You can use G to specify your own
reference point at the top of the tank. Set G=0 if you want the flange
as upper reference point. G is defined as positive if you use an
upper reference point above the
TR Pro Reference Point. For tanks
with an ullage plug for hand dipping the
Tank Ullage Reference
Point (dipping mark)
can be used as upper reference point, but you
can use other reference points as well
2 The Tank Height (R) is defined as the
distance between the upper reference
point (specified by the Distance Offset G)
and the lower reference point (zero level).
3 Set the Minimum Level (C).
The Minimum Level Offset is always
positive and is defined as the distance
between the zero level (
Tank Level Refer-
ence Point
) and the minimum accepted
level. Normally you set the C distance in
order to extend the measurement range to
the tank bottom.
4 Set the Calibration Distance. It should
normally be set to zero but can be used to
compensate for systematic errors due to
e.g. disturbances from the tank nozzle.
This may be the case if the gauge is
mounted in a nozzle which does not
conform to the free space requirements.
