Propane

Reading your propane tank fuel gauge is not complicated, but can be confusing. First, you must locate the gauge by looking under the dome of your propane tank. There you will find black numbers surrounding the circumference of the gauge and a pointer needle indicating a percentage.

Based on the physical properties of propane, tanks are considered full when the gauge reads 85%. This allows for any expansion of propane vapor. If your gauge ever falls below 20% you should contact Gerner Energy immediately at 410-472-2022 for a refill. It is safest to refill your tank before the gauge falls below 20%.

  • DOT cylinders are those that meet the Department of Transportation’s specifications. These cylinders are smaller than ASME tanks and are designed with portability in mind. For example, you might use a DOT cylinder to power your grill. Much larger DOT cylinders might stay in one place because of their size, but they can still technically be relocated even when full. Because transporting propane poses certain risks, though, those who do so must follow specific regulations set forth by the DOT. They must also maintain their tanks, which means arranging for recertification 12 years after the original manufacture date and then every five years for the life of the cylinder.
  • ASME tanks get their name from the American Society of Engineers. These vessels are designed for permanent installation on a property. Because they have thicker steel and are not exposed to the same hazards that mobile DOT cylinders are, recertification is not required. ASME tanks are measured in gallons. Common tank sizes range from 120 gallons to 2,000 gallons. The capacity of DOT cylinders, on the other hand, is measured in pounds of water. They might range in size from 5 pounds to 420 pounds.

Cathodic protection prevents corrosion by applying DC current from an external source, forcing the tank to become cathode. Sacrificial systems are used when the amount of current required for the protection is small, such as in underground propane tanks.
