9.1.3
Input of fluid parameters
Fluid temperature
The fluid temperature is used:
– at the beginning of the measurement for the interpolation of the sound speed and therefore for the calculation of the
recommended transducer distance
– during the measurement for the interpolation of the density and the viscosity of the fluid
This value is only used, if the fluid temperature is not measured. The value has to be within the ambient temperature of the
transducers.
• In case of a temperature range, enter the average fluid temperature.
• Press ENTER.
Fluid pressure
The fluid pressure is used for the interpolation of the sound speed and the gas compressibility coefficient.
• Enter the fluid pressure.
• Press ENTER.

Other parameters
Extension cable
In case the transducer cable is extended (e.g., between junction box and transmitter), enter the length of the extension
cable.

Notice!
If the relation between the sound speed and the temperature is not linear, see the sound speed-temperature curve.
