Abstract
It is shown that use of the classical form of the least squares method to analyze measurements of the mass of petroleum products in storage tanks by DMSs (data-measurement systems) incorrectly estimates the errors of the coefficients of the calibration curves of the differential pressure gages used in these systems. This article presents an algorithm for analyzing these measurements when made on the basis of hydrostatic pressure. The algorithm accounts for errors of the argument of the measurement function (in the given case, the errors of the standard pressure control-point setting mechanisms).
