5. Install the temperature sensors in the same circuit as
the meter.
6. Seal temperature sensors and screw connections to
prevent manipulation.
7. Remove the rubber band from the volume measuring
part. During operation, the temperature sensor cable
and control line should not be in direct contact with the
volume measuring part.
8. If you install the meter as a cooling meter, follow the
corresponding instructions.
Recommendation: If you install several meters, the
same installation conditions should apply to all meters.
4.1 Changing the installation location
Note
The installation location can be changed in the field if
this function has been enabled at the factory. This
function locks after 5 changes and can then no longer
be used. The entries can be checked via the LCD loop
"LE".
Note
Alternatively, you can change the installation location
using UltraAssist.
Note
If the "PoS" symbol is not displayed, this function is
not available.
For meters with an adjustable installation location, the
installation location can be determined manually. Proceed as
follows:
• Press and hold the Service button (for more than 3
seconds) until "Para" appears on the LCD.
• Press button 2 briefly until "F8" appears on the LCD.
• Press button 1 briefly several times until "PoS" appears
on the LCD.
• Briefly press button 2 to display the current installation
location. Depending on the installation location, "PoS
Cold" or "PoS Hot" is displayed.
• To change the installation location, press button 1.
The display changes.
• Press button 2 briefly until
• To complete the parameterisation, briefly press button
1 several times until "nb-----" appears on the LCD.
• Press button 2 briefly to complete the change.
• The change can be checked using the symbols (
) on the LCD.
• If necessary, adjust the temperature sensors according
to the installation requirements.

4.2 Installation recommendations

• During installation, make sure that water cannot enter
into the calculator during operation.
• Inlet or outlet sections are not necessary but are
recommended.
• If you install the meter in the common return of two
circuits, select an installation location with a minimum
distance of 10 × DN from the T-piece.

• The temperature sensor ends should reach at least into
the middle of the pipe cross-section.

Figure 5: Integration for circuit with throttle circuit, for
example (flow sensor in flow direction before the control
valve/differential pressure regulator)
4.4 Installation instructions for the adapter set
(direct immersion temperature sensor)
An installation set is included for meters with a Ø 5.2 × 45
mm temperature sensor. This allows you to immerse the
temperature sensor directly in an installation piece or a ball
valve, for example.
