This little gadget will help.



It's a digital luggage scale for $22
  • ABS plastic, steel
  • Automatic hold feature allows you to lift luggage, set it down and then read the weight
  • Measures in lbs. or kgs. Up to 100lbs./44kg.
  • Large digital display for easy reading
I plan on using it to weigh my CO2 cylindars and propane tanks. I am also going to use it when I swap my tanks out to make sure I get a full one. I have rejected some propane swaps just cause the tank felt a bit "light".

That's a pretty nifty gadget and idea Ed!

And I thought I was done buying stuff for the brewery.

Cheap enough to have more than one and I can leave it in place.

another neat trick for propane tanks is to pour very hot water on the tank and feel where it gets cold again. i know it sounds wierd but it works great. i got six brew sessions off of one tank.

Okay silly question...How much does a full 20 lb propane tank weight full? 20 lbs?
They seem lighter then 20 lbs empty, and heavier then 20 when full.

The TARE weight should be stamped on the tank. That's the empty weight. Add that to whatever they are supposed to add and that is your full weight.

That's great...but my co2 tank is a 50#'er and between the 50 of Co2, and the tank, the whole deal must weigh around 250#...Guess I should fill the 5# bottle.

Engraved on the side of the tank should be the letters TW then a number. This number is the empty tank weight.

Each gallon of liquid propane weighs 4.23 lbs.

A 20 lb. tank has 20 lb. of propane in it when full.

Therefore 20 lb. + TW# = Total weight when full. (usually around 37-38 lbs.)

* See "Propane Tank Remainder Measurement" in the following link:
