Scope

Scope: This document specifies the terms and definitions, classification, metrological requirements, technical requirements, and test methods for electronic water meters. This document is applicable to electromagnetic water meters, ultrasonic water meters, and jet water meters used to measure the flow of drinking water in closed full pipes, with temperature grades of T30 and T50. Other types of electronic water meters can also be implemented as a reference. Main technical content: Based on the differences in the working principles, structures, and operating modes between electronic water meters and mechanical water meters, and on the basis of GB/T 778-2018 and JJG 162-2019, combined with the characteristics of electronic water meters (mainly ultrasonic water meters, electromagnetic water meters, and jet water meters), a systematic evaluation of their performance is carried out, which can provide technical guidance for electronic water meter manufacturers, technical institutions, and water meter users.
