Does Cold Temperature Affect a Propane Tank Level Gauge?
Propane is similar to the majority of other types of materials in that it is affected by cold temperatures. The propane gas contracts as 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 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 rise as much as anticipated.

Propane Tank Level Gauge
The propane tank's gauge shows you what fraction of the tank is full. Usually, tanks are not filled over 80% in order to enable the gas to expand on warm temperatures. Like for instance, a 500 gallon tank, at a reading of 80% at normal temperatures reflects approximately 400 gallons of propane in the tank. This is roughly the amount which is able to be stored.

Normal Temperatures
The web site Propane 101, that 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 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 would read lower. Similarly, 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 amount of energy contained or energy contained in a tank would not change when the gas either contracts or expands, 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 receive roughly 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 would 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 will cause a smaller increase reading on the propane gauge.
