Canadian alcoholometric table anomalies

[meerkat]

I have had queries from distillers who noticed that some of the gauging calculations they performed using the Canadian Alcoholometric Tables did not agree exactly with the results they obtained from the AlcoDens software. The reason for the discrepancies is that the Canadian tables are a hybrid of the TTB "in air" values and the OIML "in vacuum" values. When these distinctions are taken into account the tables and AlcoDens agree very well.

The Canadian tables do not include blending calculations so the values obtained from these tables have to be interfaced with other systems for further processing. This makes it important that the basis for the numbers in the tables is understood.

For those who are interested I have written up a comparison of the examples in the Canadian tables with the values obtained from AlcoDens to illustrate how the Canadian tables should be used.
