3.10 Level Unit – Temperature Data
The Temperature Data-window shows the dynamic data and
the database values for the temperature measurement.
Select a new tank by hitting the Tank-button or by hitting the
up or down arrow keys.
The dynamic data box shows:
• Int temp. The internal temperature measured by a
sensor inside the Transmitter is displayed.
• Temp avg. The average temperature calculated as the
average of the values from the sensors that are im-
mersed in the liquid.
• Temp 1, 2 or 3. The value from each individual sensor is
displayed.
The following status are shown:
Note: Temperature sensor number 1 is the lowest sensor. If only
two sensors are used, these will be number 1 and 2, with number 1
as the lowest.
• TX comfail indicates that the transmitter is not commu-
nicating. This produces an alarm on the alarm row.
• Int temp fail. The internal temperature measurement
has failed when the box is checked.
• Avg error. This box is checked if it was not possible to
calculate any average temperature. For example if there
is no temperature sensor in the liquid.
• Temp 1, 2 or 3 fail. This temperature sensor does not
produce an acceptable value.
• Int Temp valid. This box is checked when the internal
temperature sensor is producing an acceptable value.
