Definition of technical unit Barrel (bbl), given in gallons per
barrel.
US: US gallons
Imp: Imperial gallons
User def.: free to set the conversion factor.
Format 9; 9.9; 9.99; 9.999 Number of places after the decimal point
!
Note!
Only visible if the "Random" system unit has been selected.
Meter coeff. Pulse value
K-factor
Select the reference variable for the pulse value.
Pulse value (unit/pulse)
K-factor (pulse/unit)
Pulse value 0.001 to 99999 Setting as to what volume flow (in dm
3
or litre) a pulse of the
flow transmitter corresponds to.
!
Note!
Only available for Pulse signal.
K Fact. unit Pulse/dm
3
Pulse/ft
3
K-factor 0.001 to 9999.9 Enter the pulse value of the vortex sensor. You can find this
value on your flow sensor.
!
Note!
This can only be selected for the PFM signal.
For vortex sensors with pulse signal, the reciprocal value of the
K-factor (in pulse/dm
3
) is entered as a pulse value.
Start value 0.0000 to 999999 Start value for the volume flow (differential pressure) with 0 or
4mA.
!
Note!
This can only be selected for the 0/4 to 20 mA signal.
End value 0.0000 to 999999 End value for the volume flow (differential pressure) with 20
mA.
!
Note!
This can only be selected for the 0/4 to 20 mA signal.
Flow cut off 0.0 to 99.9%
4.0 %
Below the set value, the flow is no longer recorded or 0 is set.
Depending on the type of flow transmitter, the flow cutoff can
be set in % of the full scale value of the flow measuring range
or as a fixed flow value (e.g. in m
3
/h).
Correction Yes
No
Possibilities for correcting the flow measurement by offset,
signal damping, flow cut off, sensor expansion coefficient and
correction table for curve description.
Signal damp 0 to 99 s Time constant of the first order low pass for the input signal.
This function is used to reduce display fluctuations in the event
of severely fluctuating signals.
!
Note!
This can only be selected for the 0/4 to 20 mA signal.
Offset -9999.99 to 9999.99 Shifts the zero point of the response curve. This function is
used to adjust sensors.
!
Note!
This can only be selected for the 0/4 to 20 mA signal.
Correction Yes
No
Possibility for correcting the flow measurement. If "YES" is
selected, the sensor curve can be defined in the correction
table and there is the possibility of compensating the
temperature effect on the flow transmitter (see "Exp. coeff.")
