6.4.1.7 Determine absolute and relative error for the results of
measuring the density by means of areometer.
Absolute error of measuring is the absolute magnitude of
the difference between the average magnitude of the measurement

and the magnitude of individual measurement.

Table 6.3 – The results of determining the density of liquid (oil,
gas condensate or oil product) by means of areometer and

calculations.
