Flow measurement problems

Problem Possible causes
Non-zero flow reading •
at no-flow conditions
or at zero offset •
•
116
Possible cause
A meter verification test is in pro-
gress, with outputs set to Last Meas-
ured Value.
Sensor simulation is enabled.
There is a memory error in the dis-
play module.
A flowing density calibration is in
progress.
A D1 density calibration is in pro-
gress.
A D2 density calibration is in pro-
gress.
A D3 density calibration is in pro-
gress.
A D4 density calibration is in pro-
gress.
A zero calibration is in progress.
Flow through the device is in the re-
verse direction (against the flow ar-
row).
Misaligned piping (especially in new instal-
lations)
Open or leaking valve
Incorrect sensor zero

Recommended actions
• Allow the procedure to complete.
• Disable sensor simulation.
• Cycle power to the meter.
• Replace the display module.
• Contact customer support.
• No action required.
• No action required.
• No action required.
• No action required.
• No action required.
• No action required.
• No action required.
Recommended actions
• If the reading is not excessively high, re-
view the live zero. You may need to restore
the factory zero.
• Check for open or leaking valves or seals.
• Check for mounting stress on the sensor
(e.g., sensor being used to support piping,
misaligned piping).
• Contact customer support.
