This technical specification completes the requirements, already specified in the relevant parts of UNI/TS 11291 series, in order to allow interchangeability of meters with Qmax > 10m3/h and ≤ 160 m3/h and Pmax ≤ 0,5 bar that make available only volumes at reference conditions, that communicate in point-to-point mode, supporting GPRS/UMTS/LTE or NB-IoT communication standard.
Part 13-2 defines the subset of the data model specified for interchangeability with exclusion of objects needed to manage the transmission media.
