Reported Problem
Possible Solutions
Flow rate is indication zero flow.
(When fluid is flowing in the pipe.)
• Verify that the correct supply voltage is
present at the flow meter power input.
• Verify that the flow meter signal outputs
are properly wired to the display.
• For insertion meters, verify that the
meter is correctly inserted and parallel
with the pipe.
• For turbine meters, verify that the turbines
are not clogged with debris.
• Re-confirm that there is really flow in the
pipe.
Displayed flow rate is too high or too low.
• Verify that the serial number of the flow
meter matches the serial number shown
on the label inside the D-100 front cover.
• Verify that the correct supply voltage is
present at the flow meter power input.
• Verify that the pipe diameter matches the
diameter shown on the calibration
certificate and on the flow meter tag.
• For insertion meters, verify that the
meter is correctly inserted and parallel
with the pipe.
• For turbine meters, verify that the turbines
are not clogged with debris.
Ai3 and/or Ai4 sensor values are too high or
too low.
• Verify that the sensor scaling matches
that programmed values shown on the
label inside the D-100 front cover and on
the calibration certificate.
• Confirm that the control system is
correctly scaled.
Data is not available at the control system.
• Verify network addresses are properly
programmed into the D-100.
• If applicable, verify the Baud rate.
• Check the polarity of the network
connections.
