A Scientometric study was conducted by querying the Web of Science database for the field of "natural gas". Based on the data obtained from Web of Science, the bibliometric relays were built using VOSviewer software. Bibliometric networks are useful for establishing the direction of research. The connections created in this software indicate your publications, magazines, researchers, the countries in which it was published, your interest in the subject of "natural gas" depending on the years. Product quality management and risk management proposes the elaboration of a set of procedures through which to design a gas meter that can prevent and reduce unauthorized interventions on gas meters. Keywords: Natural gas, gas meter, Web of Science, VOSviewer, management 1. Introduction All over the world, natural gas distribution companies are trying to make their balance between the gas bought by the company and the one distributed or supplied to consumers more efficient. This efficiency is achieved through a good maintenance on the entire distribution system, starting from the delivery / reception states, continuing with the distribution network, reaching the regulation- measurement equipment of the domestic or non-household consumers. Depending on the legislation in force in each country, the gas losses suffered by a natural gas distribution company are due to leaks in the distribution system, faulty measuring devices or due to unauthorized consumption.[1] Gas losses or unmetered consumption are called technological consumption, they being managed in Romania by ANRE (National Energy Regulatory Authority) and added to a certain extent to the final price to the consumer. Unauthorized intervention on a distribution system can be done in two ways, either by bypassing the natural gas measuring device completely, or by direct intervention on it, so that its measurement is not a real one. The current trend for unauthorized consumption is growing. According to the ANRE monitoring report in January 2021 in Romania there are 4182330 consumers, of which 3953330 are household consumers, and 229030 are non-household consumers.
