The device is not
measuring the flow
rate correctly. • Check that the K-factor matches the
fitting used
• Check that the KW value has not been
switched
• Perform a Teach-In process to deter-
mine the K-factor for the fitting used
Green 4 to 20 mA Depending on the
switching thresh-
olds or switched
a
The displayed flow
rate is not zero
even though the
flow rate in the pipe-
line is zero. • Check that the flow rate in the pipeline
is zero-
• Check that there are no air bubbles in
the pipeline-
• Check the filter level-
• Calibrate the flow rate zero point.
Green 4 to 20 mA Depending on the
switching thresh-
olds or switched
a
The displayed flow
rate is always zero. • Check that the flow rate in the pipeline
is not zero.
• Check that the K factor or KW value
are not too low.
• Check that the measuring electrodes
are mounted so that they are perpen-
dicular to the direction of flow.
• Select a smaller flow rate unit or in-
creased the number of decimal places
displayed.
Green 4 to 20 mA Depending on the
switching thresh-
olds or switched
a
The displayed flow
rate is not stable. • Check whether the medium is flowing
in the pipeline
• Select a higher filter
Green 4 to 20 mA Depending on the
switching thresh-
olds or switched
a
The flow rate dis-
play is changing at
a very slow place. • Check whether the medium is flowing
in the pipeline
• Select a smaller filter
