Does Cold Affect the Level Gauge on a Propane Tank?
Propane is like the majority of other kinds of materials in that it is affected by cold temperatures. The propane gas contracts as the temperature declines. That reduced level of gas in the tank is reflected by the gauge that reflects the level on the propane tank. Often, this occurs whenever a homeowner checks the gauge in cold conditions and sees the amount of the tank level before and after delivery. Depending upon the weather conditions, the level on the tank might not go up as much as anticipated.

Propane Tank Level Gauge
The propane tank's gauge shows you what portion of the tank is full. Usually, tanks are not filled more than 80% so as to enable the gas to expand during hot days. For instance, a 500 gallon tank, at a reading of 80% at normal temperatures reflects about 400 gallons of propane inside the tank. This is around how much could be stored.

Normal Temperatures
The propane industry manages the popular web site Propane 101, that considers the propane baseline point to be an exterior temperature of 60 degrees. Like for instance, if the gauge reads 50% of capacity on a day when the temperature is near 60 degrees, then a 500 gallon tank would contain roughly 250 gallons of propane. If the temperature that day is much lower than 60 degrees, the gauge would read lower. Also, if the temperature is much higher than 60 degrees, the gauge will actually read higher because the gas expanded.

Effect of Expansion and Contraction
The energy contained or amount of energy contained in a tank would not change as the gas either contracts or expands, according to the propane industry web site. The amount of propane itself has not changed, but only the density of the gas has changed.

Cold-Weather Delivery
The homeowner who orders 100 gallons of propane will receive about 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, these chillier temperatures will result in a smaller increase reading on the propane gauge.
