Configuration/Operation
Temperature sensor element positions
The temperature elements are numbered from the bottom of the tank and upwards. Enter the position
of each element, measured as the distance from the Zero Level (Dipping Datum Plate) to the
temperature element. If you use average temperature elements, enter the position of the terminating
level of each sensor element.

Tank average temperature calculation
You can exclude certain spot elements from the average temperature calculation. This may be useful if,
for example, the temperature close to the surface or close to the bottom of the tank deviates
significantly from the temperature in the rest of the tank. This may also be accomplished by setting an
appropriate value for the Insert Distance parameter, see
“Insert distance” on page 52 .
Note
A faulty temperature sensor will affect the temperature calculation. For more information see “Ground
fault detection” on page 111 .
