Maintenance
Normally,
WIKA
WMI
Series Magnetic Level Indicators
operate free from maintenance
and wear when applied
properly. Depending on the application, occasionally mud or other floating substances can gather in the lower
portion of the instrument. Should this be the case, follow the below steps to remove the gauge from service.
1.
Isolate the chamber from service by closing the process valves starting with the lower valve and then the top
valve.
2.
Allow pressure to equalize with atmosphere by slowly opening the vent connection.
3.
Drain off any remaining liquid in a manner compatible with plant requirements.
4.
Remove the flange on the bottom of the gauge.
Caution!
Take care to not allow the float to drop on the floor.
This can cause damage to the float and/or the magnet assembly.
5.
Clean out chamber with a brush and wash with water if compatible. Make sure there are no remaining solid
particles. Look for items or debris that will inhibit the movement of the float. Further inspect the gauge
chamber to ensure that it is free from unexpected corrosion or damage.
6.
Replace the float with the arrows in the “Up” position.
7.
Using a new gasket, replace the bottom flange and tighten all fasteners to the proper torque.
