Does Cold Temperature Actually Affect the Level Gauge on a Propane Tank?
Propane is similar to the majority of other kinds of materials in that it is affected by cold temperatures. The propane gas contracts when the temperature declines. That reduced level of gas in 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 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 propane tank's gauge shows you what portion of the tank is full. Typically, tanks are not filled over 80% in order to enable the gas to expand on hot days. For instance, a 500 gallon tank, at a reading of 80 percent at normal temperatures reflects around 400 gallons of propane in the tank. This is around how much can be stored.

Normal Temperatures
The website Propane 101, which is operated by the propane industry, considers an exterior temperature of 60 degrees to be the baseline or reference point. Like for instance, if the gauge reads 50 percent of capacity on a day when the temperature is near 60 degrees, then a 500 gallon tank would contain about 250 gallons of propane. If the temperature that day is a lot lower than 60 degrees, the gauge will read lower. In the same way, if the temperature is much higher than 60 degrees, the gauge would actually read higher due to the expansion of the gas.

Effect of Expansion and Contraction
According to the information provided by the propane industry web site, the amount of energy contained inside the tank does not actually change as the gas expands or contracts. 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 would be given around 424 pounds of propane. With the delivery of 100 gallons, the homeowner with a 1000 gallon propane tank can 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 conditions, these chillier temperatures will result in a smaller increase reading on the propane gauge.
