What is the maximum permitted length for a retail discharge hose?

The main idea is that there is a limit to how long a retail discharge hose can be without hurting measurement accuracy and safety. A maximum length of 18 feet is used because the hose contains liquid that isn’t measured by the meter when the sale is charged—the dead volume. The longer the hose, the more unmetered liquid stays in the line, and the more pressure drop, temperature and evaporation effects, and potential leaks can affect the amount actually dispensed and billed. Keeping the hose under 18 feet minimizes these issues, helping the meter stay within its calibrated accuracy range and ensuring customers are charged correctly. Shorter lengths would be more accurate but may be impractical for installation, while longer lengths would worsen accuracy and safety, which is why the limit is set at 18 feet.
