10.3 Flow measurement problems
Flow measurement problems and recommended actionsTable 10-3:
Problem Possible causes Recommended actions
Flow indication at no
flow conditions or
zero offset
• Misaligned piping (especially in new in-
stallations)
• Open or leaking valve
• Incorrect sensor zero
• Verify that all of the characterization parame-
ters match the data on the sensor tag.
• If the flow 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 Micro Motion.
