Meters for cold potable water and hot water

NCh 3274/1:2018 "Medidores para agua potable fría y agua caliente- Parte 1: Requisitos metrológicos y técnicos" (Chilean Standard NCh 3274/1:2018 "Meters for cold potable water and hot water - Part 1: Metrological and technical requirements") (66 pages, in Spanish)

The notified standard specifies the metrological and technical requirements for new water meters for cold potable water and hot water flowing through a fully charged, closed conduit. These water meters incorporate devices which indicate the integrated volume.

In addition to water meters that operate mechanically, the standard also applies to devices that operate electrically, electronically or mechanically incorporating electronic devices, and that are used to measure the volume of hot or cold potable water. The standard also applies to electronic auxiliary devices. Auxiliary devices are optional. However, it is possible that the competent authority could make some auxiliary devices mandatory.
