If Other Medium is selected, the fluid parameters have to be entered first:
• average sound speed of the fluid
• range around the average sound speed of the fluid
• kinematic viscosity
•density
11.2.1 Sound Speed
The sound speed of the fluid is used for the calculation of the transducer distance at the beginning of the measurement.
However, the sound speed does affect the measuring result directly. Often, the exact value of the sound speed for a fluid
is unknown. Therefore, a range of possible values for the sound speed has to be entered.
11.2.2 Kinematic Viscosity
The kinematic viscosity influences the flow profile of the fluid. The entered value and further parameters are used for the
profile correction.
11.2.3 Density
The density is used to calculate the mass flow (product of the volumetric flow rate and the density).
11.2.4 Fluid Temperature
The fluid temperature is used for the interpolation of the sound speed and therefore for the calculation of the recommend-
ed transducer distance at the beginning of the measurement.
During the measurement, the fluid temperature is used for the interpolation of the density and viscosity of the fluid.
11.2.5 Fluid Pressure
The fluid pressure is used for the interpolation of the sound speed.
Enter the average sound speed of the fluid. Press ENTER.
This display will only be indicated if Other Medium is selected.
Select auto or user. Press ENTER.
auto: The area around the average sound speed is defined by the transmitter.
user: The area around the average sound speed has to be entered.
Enter the range around the average sound speed of the fluid. Press ENTER.
This display will only be indicated if user is selected.
Enter the kinematic viscosity of the fluid. Press ENTER.
This display will only be indicated if Other Medium is selected.
Note! If the mass flow is not measured, press ENTER. The other measuring results will not be affected.
Enter the operating density of the fluid. Press ENTER.
This display will only be indicated if Other Medium is selected.
Enter the fluid temperature. The value has to be within the operating temperature range of
the transducers. Press ENTER.
Enter the fluid pressure. Press ENTER.
This display will only be indicated if Special Funct.\SYSTEM settings\Dialogs/
Menus\Fluid pressure is activated.
