Does Cold Affect the Level Gauge on a Propane Tank?
Propane is like the majority of other types of materials in that it is affected by cold temperatures. The propane gas contracts when the temperature declines. That reduced level of gas inside the tank is reflected by the gauge which reflects the tank level. Usually, this happens whenever a homeowner checks the gauge during cold climate and sees the amount of the tank level before and after delivery. Depending on the weather, the level on the tank might not rise as much as anticipated.

Propane Tank Level Gauge
The gauge on the propane tank would show what fraction of the gas tank is still full. Tanks are normally not filled over 80% full because this would allow for the gas to expand on hotter temperatures. Like for instance, a 500 gallon tank, at a reading of 80 percent at normal temperatures reflects around 400 gallons of propane inside the tank. This is around how much could be stored.

Normal Temperatures
The propane industry operates the popular website Propane 101, that considers the propane reference point to be an exterior temperature of 60 degrees. Like for example, if the gauge reads 50% of capacity on a day when the temperature is close to 60 degrees, then a 500 gallon tank would contain about 250 gallons of propane. If the temperature that day is much lower than 60 degrees, the gauge will read lower. Also, if the temperature is much higher than 60 degrees, the gauge would actually read higher due to the expansion of the gas.

Effect of Contraction and Expansion
The energy contained or amount of energy contained within a tank would not change as the gas either expands or contracts, based on the propane industry website. The amount of propane itself has not changed, but just the density of the gas has changed.

Cold-Weather Delivery
The homeowner who orders 100 gallons of propane will be given roughly 424 lbs. of propane. With the delivery of 100 gallons, the homeowner with a 1000 gallon propane tank could expect the guage to go up by 10%. These numbers will be correct if the temperatures were close to 60 degrees at the time of delivery. If the delivery took place during colder weather, these chillier temperatures will cause a smaller increase reading on the propane gauge.
