Fluid density
The density is used to calculate the mass flow.
If the mass flow is not measured, an input is unnecessary. The default value can be used.
• Enter the operating density of the fluid.
• Press ENTER.
This display will only be indicated if
Other Medium is selected.
Fluid temperature
At the beginning of the measurement, the fluid temperature is used for the interpolation of the sound speed and therefore
for the calculation of the recommended transducer distance.
During the measurement, the fluid temperature is used for the interpolation of the density and viscosity of the fluid.
The value entered here is used for the calculation if the fluid temperature is not measured.
• Enter the fluid temperature. The value has to be within the operating temperature of the transducers.
• Press ENTER.
9.1.3 Other parameters
Transducer parameter
If transducers are identified at a measuring channel, the input of parameters is finished.
• Press ENTER. The main menu will be displayed.
If no or special transducers are connected, the transducer parameters have to be entered.
• Select Standard to use the standard transducer parameters stored in the transmitter.
• Select Special Version to enter the transducer parameters. The transducer parameters have to be provided by
FLEXIM.
• Press ENTER.
If
Special Version
is selected, enter the 6 transducer parameters specified by FLEXIM. Press ENTER after each input.
Extension cable
In case the transducer cable is extended (e.g., between junction box and transmitter), enter the length of the extension cable.
• Select the menu item
Additional cable in the program branch Parameter .
• Enter the length of the extension cable.
• Press ENTER.

Notice!
If a standard transducer is selected, no transducer-specific calibration values are considered. A higher uncertainty
has to be expected.
