Functional description LIQUID DATA
SOUND VELOCITY
Use this function to display the sound velocity of the liquid. This is determined via the
LIQUID
values of the functions LIQUID and TEMPERATURE. If you edit the predetermined value,
the function LIQUID will be reset to the option OTHER.
The sound velocity of the liquid must be entered if the liquid is not available for selection
in the function LIQUID and the option OTHER was selected here.
Transmitter search range:
The measuring device searches for the measuring signal within a defined sound velocity
range. The search range is specified in the functions SOUND VELOCITY NEGATIVE or
SOUND VELOCITY POSITIVE. An error message is displayed if the sound velocity of the
liquid is outside the search range.
!
We recommend you select a smaller search range in the event of unfavorable signal
conditions (signal strength < 50%).
1 = Sound velocity liquid
n = Lower search range: defined in the function SOUND VELOCITY NEGATIVE
o = Upper search range: defined in the function SOUND VELOCITY POSITIVE
User input:
Fixed-point number 400 to 3000 m/s
Factory setting:
1487.4 m/s
VISCOSITY
This function displays the viscosity of the liquid. This is determined via the values of the
LIQUID and TEMPERATURE functions. If you edit the predetermined value the function
LIQUID will be reset to the option OTHER. The viscosity must be entered if the liquid is
not available for selection in the function LIQUID and the option OTHER was selected
here.
User input:
Fixed-point number 0.0 to 5000.0 mm
Factory setting:
1 mm
SOUND VELOCITY
Use this function to specify the lower search range for the sound velocity of the liquid.
NEGATIVE
User input:
Fixed-point number 0 to 1000 m/s
Factory setting:
500 m/s
