Notes (all models)

• Options may not be available in combination. Consult factory.
• Over range is not to exceed 10% FS above full range.
• Calibration is for water. Specify for other liquids.
• Add TOTAL height of liquid above the pressure connection to determine the correct range (dial scale).
• For elevated tanks, subtract the tank elevation from gauge reading to determine actual tank level.
