INSTALLATION
CONSIDERATIONS AND
RECOMMENDATIONS
Before you install the Rosemount 2130, consider specific installation
recommendations and mounting requirements:
• Install in any orientation in tank containing liquid
• Always install in the “on” state
(See “Electrical Installation” on page 6)
• For a high level, use the “Dry on” setting
• For a low level, use the “Wet on” setting
• Ensure the system is tested by using the local magnetic test-point
during commissioning. (See “Magnetic Test Point” on page 3-2)
• Ensure there is sufficient room for mounting and electrical connections
(see “Dimensional Drawings” on page A-5 for switch dimensions)
• Avoid installing the 2130 near to liquid entering the tank at the fill point
• Avoid heavy splashing on the forks. Increasing the time delay reduces
accidental switching caused by splashing
• Ensure that the forks do not come into contact with the tank wall, any
internal fittings, or obstructions
• Ensure there is sufficient distance between build-up on the tank wall
and the fork (see Figure 1-6 on page 1-8)
• Ensure the installation does not create tank crevices around the forks
where liquid may collect. This can happen with high viscosity and high
density liquids
• Extra consideration is needed if the plant vibration is close to the
1300 Hz operating frequency of the 2130
• Supporting the fork avoids long fork length vibration
(see Figure 1-7 on page 1-9
