Does Cold Truly Affect the Level Gauge on a Propane Tank?
Propane is similar to nearly all other types of materials in that it is affected by cold temperatures. The propane gas contracts when the temperature does down. That reduced level of gas inside the tank is reflected by the gauge that reflects the level on the tank. Usually, this occurs whenever a homeowner checks the gauge during cold weather conditions and sees the amount of the tank level before and after delivery. Depending on the weather conditions, the level on the tank may not go up as much as anticipated.

Propane Tank Level Gauge
The gauge on the propane tank will show what fraction of the gas tank is still full. Tanks are typically not filled over 80% full because this would allow for the gas to expand on warmer temperatures. For example, a 500 gallon tank, at a reading of 80 percent at normal temperatures reflects approximately 400 gallons of propane inside the tank. This is about the amount which could be stored.

Normal Temperatures
The web site Propane 101, that is managed by the propane industry, considers an exterior temperature of 60 degrees to be the baseline or reference point. For instance, if the gauge reads 50% of capacity on a day when the temperature is close to 60 degrees, then a 500 gallon tank will have around 250 gallons of propane. If the temperature that same day is a lot lower than 60 degrees, the gauge will read lower. Also, if the temperature is much higher than 60 degrees, the gauge will actually read higher due to the expansion of the gas.

Effect of Contraction and Expansion
According to the information given by the propane industry website, the amount of energy contained within the tank does not actually change as the gas contracts or expands. The amount of propane itself has not changed, but just the density of the gas has changed.

Cold-Weather Delivery
If a homeowner orders 100 gallons of propane to be delivered, they would receive 424 lbs. of propane. If the homeowner has a 1000 gallon propane tank, they could expect the gauge to go up by 10% with the delivery of 100 gallons. These numbers will be correct if the temperatures were near 60 degrees at the time of delivery. If the delivery took place during colder weather, these chillier temperatures would result in a smaller increase reading on the propane gauge.
