ES option available for the 20 ft. (6 m) range models and above.
NOTES:
• 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 correct range (dial scale).
For elevated tanks substract the tank elevation from gage reading to determine actual tank level.
