What is BS 7118-2 -   Flow measurement devices about?

BS 7118-2 is the second part of an International Standard that discusses the aspects of measurement of fluid flow. BS 7118-2 describes the procedures for fitting a quadratic, cubic, or higher degree polynomial expression to a non-linear set of calibration data, using the least-squares criterion, and assessing the uncertainty associated with the resulting calibration curve. BS 7118-2 considers only the use of polynomials with powers that are integers. Because it is not practicable to carry out this type of curve fitting and assessment of uncertainty without using a computer, it is assumed in BS 7118-2
