Sound speed range of the fluid
• Select
auto
if the area around the average sound speed is to be calculated by the transmitter.
• Select
user
if the range around the average sound speed has to be entered.
• Press ENTER.
This display will only be indicated if
Other Medium
is selected.
• Enter the range around the average sound speed of the fluid.
• Press ENTER.
This display will only be indicated if
user
is selected.
Kinematic viscosity of the fluid
The kinematic viscosity influences the flow profile of the fluid. The value is considered in the profile correction.
• Enter the kinematic viscosity of the fluid.
• Press ENTER.
This display will only be indicated if
Other Medium
is selected.
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.
Gas compressibility coefficient
The compressibility coefficient of the gas is essential for the calculation of the standard volumetric flow rate. Make sure
that the value is selected according to the operating pressure, the operating temperature and the composition of the gas.
• Enter the compressibility coefficient of the gas.
• 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 range of the transducers.
• Press ENTER.
