4.2 Select medium (MEdI)
The unit has characteristic curves for different media� Depending on the operating
mode, the following media can be selected in the menu (→ 10.4.3) :
Operating mode
Medium
REL LIQU GAS
*OIL1:
Viscosity ≥ 40 mm²/s at 40 °C / ≥ 40 cSt at 104 °F
**OIL2:
Viscosity ≤ 40 mm²/s at 40 °C / ≤ 40 cSt at 104 °F

4.3 Define the internal pipe diameter (diA)
In the operating modes LIQU and GAS the internal pipe diameter has to be en-
tered to define the volumetric flow (→ 10.2.2) �
4.4 Customer-specific calibration (CGA)
Via the calibration factor CGA the sensor can be adjusted to a reference flow in
the application�
The customer-specific calibration allows changing the gradient of the curve of
measured values� It influences the display and the outputs�
