MAINTENANCE
Mandatory, routine or scheduled maintenance should not be required for the M5000 Electromagnetic Flow Meter electronics
or flow tube after proper installation.
However, some occurrences may require personnel to perform the following:
• Flow tube and electrode cleaning
• Circuit board replacement
WARNING
DO NOT CLEAN COMPONENTS INSIDE THE AMPLIFIER OR JUNCTION BOX.
Cleaning the Flow Tube and Electrode
At times flow tube, electrodes, amplifier/junction box housings and the amplifier window may need cleaning, depending on
process fluid properties, fluid flow rate and surrounding environment.
Clean the flow tube and electrodes by following the material handling and cleaning procedures documented in the Material
Safety Data Sheet (MSDS) guidelines for the products(s) that were in contact with the flow tube and electrodes.
Should flow tube and/or electrode cleaning become necessary:
1. Disconnect detector from pipeline.
2. Clean electrodes according to MSDS guidelines.
3. Reconnect detector to pipeline.
Replacing Circuit Board
If the circuit board is damaged, follow these instructions to replace it.
1. Unplug the electrode and coil plugs.
2. Unscrew and remove screws S1-S4.

4. Remove the old circuit board.
5. Insert the new circuit board.
6. Secure it by fastening S1-S4 screws. Plug in the electrode and coil plugs.
7. If necessary, congure new circuit board related to the available meter (detector, size).
