If

Other Medium

is selected or no data set for the selected fluid is stored in the transmitter, 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
• gas compressibility coefficient

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

Gas Compressibility Coefficient

The compressibility coefficient of the gas is essential for the calculation of the standard volumetric flow rate (see section
3.2.1). Note that the value is to be selected correspondingly to the operating pressure, the operating temperature and the
composition of the gas.

11.2.5

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 as well as for the interpolation of the compressibility coefficient of the gas 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.

Enter the average sound speed of the fluid. Press ENTER.
This display will only be indicated if

is selected.

Select

: 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 or no data set for the se-

lected fluid is stored in the transmitter.

Enter the operating density of the fluid. Press ENTER.
This display will only be indicated if

Other Medium

is selected or no data set for the se-

lected fluid is stored in the transmitter.

Enter the compressibility coefficient of the gas. Press ENTER.
This display will only be indicated if

Other Medium

is selected or no data set for the se-

lected fluid is stored in the transmitter.

Enter the fluid temperature. The value has to be within the operating temperature range of
the transducers. Press ENTER.
