Does Cold Affect the Level Gauge on a Propane Tank?
Like the majority of other kinds of materials, propane is affected by cold temperatures. When the temperature goes down, the propane gas contracts. That reduced level of gas in the tank is reflected by the gauge which reflects the level on the tank. Often, this occurs whenever a homeowner checks the gauge in cold weather conditions and sees the amount of the tank level before and after delivery. Depending on the weather, the tank level might not rise as much as anticipated.

Propane Tank Level Gauge
The gauge on a propane tank shows you what portion of the tank is full. Typically, tanks are not filled over 80% so as to allow the gas to expand during warm days. Like for instance, a 500 gallon tank, at a reading of 80% at normal temperatures reflects roughly 400 gallons of propane inside the tank. This is around the amount that is able to be stored.

Normal Temperatures
The propane industry manages the popular website Propane 101, that considers the propane baseline point to be an exterior temperature of 60 degrees. Like for instance, if the gauge reads 50 percent of capacity on a day when the temperature is close to 60 degrees, then a 500 gallon tank would have roughly 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 because the gas expanded.

Effect of Contraction and Expansion
According to the information given 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
If a homeowner orders 100 gallons of propane to be delivered, they will receive 424 pounds of propane. If the homeowner has a 1000 gallon propane tank, they can expect the gauge to go up by 10% with the delivery of 100 gallons. These numbers will be accurate if the temperatures were close to 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.
