Accuracy
Accuracy of Magnetel gauge dial indication estimated ±10% as a percent of full scale. Accuracy depends upon proper gauge sizing. Accuracy may be less for some tank shapes and sizes. Accuracy may be less near full and empty. Accuracy may be less if tank is not level. This gauge is not to be used for filling.

Caution: This gauge is not a substitute for an automatic overfill prevention device, which may be required for filling. This gauge is not to be used as an unattended means of determining tank overfilling. This document does not provide instructions for tank filling. Periodic annual operability checks may be required which are necessary to detect gauge malfunctions and/or inaccurate gauge readings. Gauge accuracy depends upon proper gauge sizing and installation. Release of tank contents as well as damage and safety hazard may result if tank is overfilled. Fuel exhaustion may occur if tank contents are less than indicated.

Precaution for LPG and NH3: Accurate measurement of Liquefied-Petroleum Gas (LPG), or Anhydrous Ammonia (NH3), requires converting a volume measured at an observed temperature to the volume at a standard base temperature of 60°F. LP Gas is usually a mixture of propane, butane and possibly other gases, so the conversion factor is usually determined from a chart when the specific gravity of the LP Gas is at 60°F is known.
