Installation Considerations and Recommendations
Before you install the Rosemount 2110 Level Switch, consider specific installation
recommendations and mounting requirements.
• Install in any orientation in tank containing liquid.
• Always install in the normally “on” state
• For high level recommendation is Dry = on (see “Function” on page 2-6).
• For low level recommendation is Wet = on (see “Function” on page 2-6).
• Always ensure the system is tested by using the local magnetic test point during
commissioning (see “Magnetic Test Point” on page 3-1).
• Ensure sufficient room for mounting and electrical connection (see “Dimensional
Drawing” on page A-5).
• Ensure that the forks do not come into contact with the tank wall or any internal fittings
or obstructions.
• Ensure the forks does not come into contact with the tank wall of any internal fitting.
• Avoid installing the 2110 where it will be exposed to liquid entering the tank at the fill
point.
• Avoid heavy splashing on fork
• Avoid product buildup
• Ensure no risk of bridging the forks.
• Ensure there is sufficient distance between build-up on the tank wall and the fork.
• Ensure installation does not create tank crevices around the forks where liquid may
connect (important in high viscosity and high density liquids).
• Extra consideration is needed if the plant vibration is close to the 1300 Hz operating
frequency of the 2110.
• Ensure sufficient clearance for the fork so highly viscous liquids quickly flow off the
forks.
• Extra consideration is needed if the plant vibration is close to the 1300 Hz operating
frequency of the 2110.
