Potential Cause
Corrective Action
Grounding/Wiring
Fault
Grnd/Wire Fault
Improper installation of wiring
See “Sensor Connections” on page 2-11
Coil/Electrode shield not connected
See “Sensor Connections” on page 2-11
Improper process grounding
Faulty ground connection
Check wiring for corrosion, moisture in the terminal block,
and refer to “Grounding” on page 5-12
Sensor not full
Verify sensor is full and empty pipe diagnostic is on
High Process Noise
Hi Process Noise
Slurry flows - mining/pulp stock
Decrease the flow rate below 10 ft/s (3 m/s)
Complete the possible solutions listed under “Step 2:
Process Noise” on page 4-7
Chemical additives upstream of the
sensor
Move injection point downstream of the sensor, or move
the sensor
Complete the possible solutions listed under “Step 2:
Process Noise” on page 4-7
Electrode not compatible with the
process fluid
Refer to the Rosemount Magnetic Flowmeter Material
Selection Guide (00816-0100-3033)
Air in line
Move the sensor to another location in the process line to
ensure that it is full under all conditions
Electrode coating
Use bulletnose electrodes
Downsize sensor to increases flowrate above 3 ft/s (1 m/s)
Periodically clean sensor
Styrofoam or other insulating particles
Complete the possible solutions listed under “Step 2:
Process Noise” on page 4-7
Consult factory
Low conductivity fluids
(below 10 microsiemens/cm)
Trim electrode and coil wires - refer to “Installation” on
page 2-1
