Scope
This part of ISO 18213 presents procedures for standardizing a set of calibration data to a fixed set of
reference conditions so as to minimize the effect of variations in ambient conditions that occur during the
measurement process. The procedures presented herein apply generally to measurements of liquid height
and volume obtained for the purpose of calibrating a tank (i.e. calibrating a tank’s measurement system).
When used in connection with other parts of ISO 18213, these procedures apply specifically to tanks equipped
with bubbler probe systems for measuring liquid content.
The standardization algorithms presented herein can be profitably applied when only estimates of ambient
conditions, such as temperature, are available. However, the most reliable results are obtained when relevant
ambient conditions are measured for each measurement of volume and liquid height in a set of calibration
data.
