Fluid Pressure
The dependence of the parameters of a fluid on the pressure can be taken into account.This display will only be indicated

Error Value Delay
The error value delay is the time after which an error value will be sent to an output if no valid measured values are avail-
able.
Enter the pipe circumference. The limits for the pipe circumference are calculated on the
basis of the limits for the outer pipe diameter.
During the next scroll through the program branch
Parameter
, the outer pipe diameter
that corresponds to the entered pipe circumference will be displayed.
Example: 180 mm :
π
= 57.3 mm
Note!
The pipe circumference is only edited temporarily. When the transmitter switches back to the display
of the pipe circumference (internal recalculation), slight rounding errors may occur.
Example:
entered pipe circumference: 100 mm
displayed outer pipe diameter: 31.8 mm
When the transmitter switches back to the display of the pipe circumference, 99.9 mm will be dis-
played.
If
on
is selected, the fluid pressure will be requested in the program branch
Parameter
.
If
off
is selected, 1 bar will be used for all calculations.
Note!
For documentation purposes, it is useful to enter the fluid pressure, even if the transmitter contains
no pressure-dependent characteristic curves.
Select (

can be selected if the measuring point changes often.
In the program branch
Measuring
, the recommended transducer distance will be dis-
played in parentheses, followed by the entered transducer distance if the recommended
and the entered transducer distance are not identical.
During transducer positioning in the program branch

damping
if the damping factor is to be
used as the error value delay.
