Evaluation of uncertainty associated with totalisation of time-sampled data in gas quantity and energy measurements

Year: 2024

Type: article

Abstract: The measurement uncertainty attributed to gas quantity and energy measurements includes among others a contribution for the calculation of the total/average from time-sampled data. The aim of this paper is to establish a procedure for evaluation of this component of uncertainty, which considers contributions related to deterministic and random variations of the input data. The principal steps of the proposed procedure are (i) separation of deterministic and random components via time-domain filtering, (ii) evaluation of uncertainty associated with deterministic component by the decimation method and (iii) evaluation of uncertainty associated with random component by statistical analysis. The paper presents this evaluation procedure for a test case of time-sampled data of the superior calorific value.
