Meter Setup
Calibration Diameter
A
This parameter is set at the factory. In the event the amplifier is replaced,
verify that the pipe diameter matches the installed pipe size.
Detector Factor
A
This parameter is set at the factory. This factor compensates for accuracy
error as a result of the installed detector.
In the event the amplifier is replaced, this parameter must be
reprogrammed with the original detector zero.
Detector Zero
A
This parameter is set at the factory. This parameter compensates for
accuracy error as a result of the installed detector.
If accuracy adjustment of the meter is required, refer to the scale factor.
Amplifier Factor This parameter is set at the factory and is Read Only. This electronic
calibration factor compensates for accuracy error as a result of the
installed amplifier.
Coil Current This parameter (coil current to the detector) is set at the factory and is
Read Only. This factor compensates for accuracy error as a result of the
installed amplifier.
Scale Factor
S
Changing the scale factor lets you adjust the meter accuracy without disturbing parameters set by
the factory. You can tune the meter to meet changing application requirements in a range of ±5%
(0.95…1.05).
Power Line Frequency
S
For optimum operation of the meter, set Power Line Frequency to 50 Hz or 60 Hz in this menu at
operating location.
Excitation Frequency
A
This parameter is set at the factory. This value shows in which frequency the meter coils are
operated. Supported frequencies are dependent on the configured power line frequency and
meter size.
50 Hz 60 Hz
3.125 Hz 3.75 Hz
6.25 Hz 7.5 Hz
12.5 Hz 15 Hz
OTE: N When selecting excitation frequency, make sure to always observe that the ratio in respect
of power frequency is integer.
Empty Pipe Detection
S
ON/OFF
S
When set to ON, an Empty Pipe condition indicates to the outputs
that the meter is not completely filled. When set to OFF, empty pipe
conditions are not detected.
Threshold
S
Threshold value for empty pipe detection.
For liquids with lower conductivity or long cables, the threshold value
must be increased. The actual value can be monitored in the next
menu"Measured".
Measured Measures the real empty pipe value. This parameter is Read Only.
