UNI/TS 11291-7:2011

The provisions of resolution ARG/gas 155/08 "Instructions for the obligatory commissioning of gas metering units meeting minimum functional requirements and having remote reading and remote management functions, for all redelivery points on natural gas distribution networks" released from Authority for gas and electricity (AEEG), introduces an obligatory requirement, to be phased in gradually over time, for the commissioning of metering units meeting the minimum functional requirements established for each category, for all redelivery points on natural gas distribution networks.With the present provision the Authority shall pursue the following aims to be achieved through standardisation activity: a) to create the functional and technological conditions for the introduction of mechanisms to develop a market system for natural gas, to support the definition of the regulated market for natural gas and the new balancing service; b) to make it easier to eliminate any inefficiencies and discriminatory features by improving the process of recording and accounting for the natural gas withdrawn by consumers and introducing technological innovations to metering units; c) to improve the quality of natural gas metering, sales and distribution services, while ensuring the same functional and service levels irrespective of the operator responsible for the metering service and fostering greater awareness of consumption levels.This new part of the UNI TS 11291 family covers the technical requirements for meters with capacity more than 16 m3/h for accomplishing the relevant AEEG requirement.
