regarding wiring installation requirements.
4.
for component and/or combination cable wiring.
5.
Verify there is minimal exposed wiring and shielding.
Less than 1 inch (25 mm) is recommended.
6.
Verify that the single conduit that houses both the electrode signal and coil drive
cables do not contain any other wires, including wires from other magmeters.
Note
For installations requiring intrinsically safe electrodes, the signal and coil drive cables must be
run in Individual conduits.
12.3.4
Process fluid
1.
The process fluid should have a minimum conductivity of 5 microSiemens/cm (5
micro mhos/cm).
2.
The process fluid must be free of air and gas.
3.
The sensor must be full of process fluid.
4.
The process fluid must be compatible with the wetted materials - liner, electrodes,
ground rings, and lining protectors.

Diagnostic messages
Problems in the magnetic flowmeter system are usually indicated by incorrect output
readings from the system, error messages, or failed tests. Consider all sources in
identifying a problem in the system.
Basic Diagnostic Messages
Table 12-1:
Error message
Potential cause
Corrective action
Empty Pipe
Empty pipe
None - message will clear when pipe is full
Wiring error
Check that wiring matches appropriate wiring dia-
grams
Electrode error
Perform sensor tests - see
Conductivity less than 5 microSiemens
per cm
Increase conductivity to greater than or equal to 5
microSiemens per cm
