4 Device
Configuring the HART-compliant temperature head transmitter (min. HART 5.0) with
burst function
The output current of the temperature transmitter used should be set to "Fixed" and a
HART address other than zero (e.g. address = 1) must be set. The burst function must then
be switched on with HART command 1. This step should be performed before the
procedure described below in order to avoid a HART input error of the device being output
during commissioning.
1. Select the "Level" measuring mode via the "Measuring mode" parameter.
 Menu path: Setup → Measuring mode
L
WARNING
Changing the measuring mode affects the span (URV)
This situation can result in product overflow.
‣
If the measuring mode is changed, the setting for the span (URV) must be checked in
the "Setup" operating menu and readjusted if necessary.
2. Select a pressure unit via the "Press. eng. unit" parameter, here "mbar" for example.
 Menu path: Setup → Press. eng. unit
3. The sensor is unpressurized, perform a position adjustment →  43
4. Set the "Auto dens. corr." parameter to "External value".
 Menu path: Expert → Application
5. Perform level adjustment (wet or dry)
Result: The measured value output by the Waterpilot corresponds to the level in the deep
well corrected by means of the density characteristic line of water.
The TMT72 temperature head transmitter is not suitable for this configuration.
9.11 Linearization
9.11.1 Semi-automatic entry of a linearization table
Example:
In this example, the volume in a tank with a conical outlet should be measured in m 3 .
