Propane tank question.
I have two vertical 20# propane tanks. Is there a device that will tell me when the tanks need re-filling? I really don't want to empty them just to know that they need to be re-filled.

Just leave one tank valve closed while you use the other tank. When your propane goes out, switch tanks. You now know you will always have 20lb propane in reserve. Now you go fill the empty tank.
