1)
he device does not properly
measure the flow rate.
→
Check that the K factor corre-
sponds to the fitting used.
→
Check that the Kw coefficient has
not been disturbed.
→
Carry out a teach-in procedure
to determine the K factor of the
fitting used.
green 4-20 mA depending on
the thresholds or
switched
1)
The displayed flow rate is not
nil but the flow rate in the pipe
is.
→
Check that the flow rate in the
pipe is nil.
→
Check that there are no bubbles in
the pipe.
→
Check the filter chosen.
→
Calibrate the flow zero point.
green 4-20 mA depending on
the thresholds or
switched
1)
The displayed flow rate is
always nil.
→
Check that the flow rate in the
pipe is not nil.
→
Check that the K factor or the Kw
coefficient are not too low.
→
Check that the electrodes are per-
pendicular to the flow direction.
→
Choose a smaller flow rate unit or
increase the number of displayed
decimals..
green 4-20 mA depending on
the thresholds or
switched
1)
The displayed flow rate is not
stable.
→
Check that there is fluid in the pipe.
→
Choose a higher filter.
green 4-20 mA depending on
the thresholds or
switched
1)
The displayed flow rate
changes very slowly.
→
Check that there is fluid in the pipe.
→
Choose a lower filter.
1) If the output is configured to switch when a warning message is generated. See chap. 8.6.5.
