MAGNICATOR

OPERATION
:
1. Putting MLI in service:
• Check that the operating conditions are within the rating of the MLI. Each Magnicator has a
permanent name plate engraved with the rating and process conditions.
• Check to see that all vent and drain valves and plugs (if applicable) are securely closed.
• Flag Indication: Black = Vapor Space, Yellow = Liquid Space (all flags should be in the black
position). Alternate color flag indication: White = Vapor Space, Red = Liquid Space (all flags
should be in the white position).
• Slowly open the upper isolation valve. Upper isolation valve must be opened first to equalize the
pressure between the chamber and tank / vessel.
• Slowly open the lower isolation valve. The float will rise with the liquid level in the chamber. The
magnet assembly is positioned in the float so it will ride at the surface of the liquid (or at the
interface between two liquids when specified). Flags will turn yellow with the liquid level.
2. Preparing MLI for maintenance:
•
Close lower isolation valve.
•
Close upper isolation valve.
•
Slowly open vent valve to release the pressure from the MLI chamber.
•
Slowly open drain valve to drain liquid from the MLI chamber.
MAINTENANCE
:
The Magnicator Magnetic Level Indicator is a simple device which requires a minimum amount of maintenance.
The maintenance normally consists of cleaning the chamber. The frequency of cleaning will depend on the
process in which it is installed in. When enough foreign matter collects in the chamber to restrict the movement
of the float, it will be necessary to isolate the chamber and drain out the accumulation of dirt from the MLI. The
chamber can be flushed by using the vent and drain connections. In extreme cases, it may be necessary to
remove the float, and mechanically clean the float and chamber. Some processes may dictate the use of a
suitable solvent for cleaning. In the event the float should be removed, refer to steps given under
INSTALLATION.
Mini-Mag Float Installation Procedure
Using the following steps to install the float inside of the chamber. All other setup and maintenance procedures
should be done in accordance with the Magnicator Installation, Operation & Maintenance.
• Find the arrow on the tag that is etched onto the float. The arrow tip locates the proper pole of the magnet
inside of the float.
• Insert float into the chamber with the arrow tip, and magnet, facing towards the indicator.
Completing these steps will ensure proper coupling between the magnets in the float and the indicator during
startup and operation.
Caution: Only clean indicators with a damp cloth to avoid electrostatic charge of non-metallic components.
Certificate #CR17ATEX1001
External temperature of components and T code is based on internal process temperature. When operating with no added accessories,
the external temperature can only be equal to or less than the process temperature. Take caution when installing accessories that may
generate their own heat. Always ensure the rating of the equipment meets or exceeds the requirements of the hazardous location.
