To me that all sounds good and well if you were filling it with water, but am I right in saying liquid refridgerant weighs less than water (in our case R134A), so therefor to put 22L of R134A in would fill the liquid level to 100%, although it would weigh less than 22kg. ?_Z)PM6M6NPPkxJ7>@U`l1aU!`m}K+T+>5@=O\W{Z `cuXQ8E29EJD 1`;PH k{b;-V~a6Fw*?aC2REIUj6Fq_rZB9`'#Z8w?m/x:ylXs:[j}Z[d q/d(s6U1R co Cylinders must remain in good, secure condition.

There is no mention of a "fill ratio" to compensate as you say. The most common mistake I see is the filling ratio of R410A being < 1. The quantity of refrigerant, and type, transferred for reclamation or destruction, the person/company to whom it was transferred, and the date of the transfer. EDIT: Looks like they suggest only filling to 80% on top of the fill ratio, giving you: Tare + (Water Capacity x Fill ratio x 0.80) = maximum weight of bottle. Only talk about "refrigerant weighs less than water so you wouldn't fit that much in anyway". Does the WC already include a 20% margin?
