>Diameter<
Enter the
accurate
inner diameter of the measurement place here.
Enter inside pipe diameter
The DN number is not equal to the inner pipe diameter which, depending on pressure level
and pipe material, may significantly vary from the DN number.
Entering an incorrect inside pipe diameter inevitably leads to a faulty calculation of the
cross-sectional area resulting in faulty calculated flow readings.
Maximum inside diameter depending on version
With NFP version “25” the maximum possible inside diameter is limited to 0.55 m. Version
“28” permits to specify diameters up to 0.85 m.
>Qmin<
This parameter is to suppress lowest evaluated and indicated vol-
umes which are either undesired or not relevant.
The parameter is mainly used in permanently full large pipelines with
partially low movements or to suppress indication and output of low
leakage volumes.
Q
min
: Measurement values lower than this one will be set to “0”.
Only positive values are allowed to be set. These values are going to
be considered as absolute values and therefore have positive as well
as negative effects.
>Operation mode<
This parameter is for adjustment to existing applications. Distinguish
between:
>Cyclic (pump)<
Medium condition changes between standing
and strong movement.
Primarily for use in applications such as
