A Lesson In Propane
8:30am - When outfitting Little Scampy, a gage was put on the propane tank's incoming line in order to know when the gas in the tank was getting low. However, the gage was not accurate. When the gage was warm, the gage showed more gas in the tank. When cold, the gage showed less gas.
Often, when going to refill propane because the gage indicated low, the tank would only take 1/2 of the tank's capacity.
So, the decision was made to remove the gage and let the tank go empty. We carry two backup propane tanks which are those tiny one pound tanks used on BBQs. So, we never run out of propane.
Yesterday evening, our 20 pound tank went empty. When we connected a one pound propane tank, it appeared that this tank was empty! I was surprised! Astounded!
When connecting the 2nd backup one pound tank, it also appeared to be empty! Now I was mystified and phoned my friend Pete Olson for help [Pete lives here in Jojoba Park]. Pete came over and brought with him three one pound tanks.
All three of Pete's 1-Lb propane tanks appeared to be empty as well. Wow! Both Pete and I realized that something was wrong, but we did not know what. Pete suggested an electric heater, and he brought one over.
Researching the problem
I went online and searched for what could cause this problem. I came up with a possible answer.
When a propane tank goes empty, air may enter the incoming line. When a full propane tank is then connected, the propane mixes with that air. The result is when attempting to lite up a stove's burner, the flame either will not lite up or it will lite, then go out.
The incoming propane line needs to be purged of air. If the stove's burner is lit up repeatedly, eventually the incoming line gets purged of air.
Nice to know!
2pm - Propane Tank Gauge
After going over the hassle of using backup one pound propane tanks, I decided to return to using a propane tank gauge!
