Smart water meter CE certification process and standards——ZRLK

Author:中認聯(lián)科 time:2022-04-14 Ctr:1615

Smart watch is a new type of water meter that uses modern microtechnology, modern sensing technology, and smart IC card technology to measure water volume, transmit water data and settle transactions. It is a must for every family whether it is at home or abroad. After the smart water meter is installed and used, it can not only measure the user's monthly water flow more accurately, but also pay the bills directly online, which is very convenient. However, if the smart water meter wants to export to the EU market, it needs to apply for CE certification.

The necessity of CE certification for smart water meters

CE certification provides a unified technical specification for the trade of products from various countries in the European market and simplifies the trade procedure. To enter the European Union and the European Free Trade Area, the products of any country must be CE certified, and the CE mark should be affixed to the product. Therefore, CE certification is a passport for products to enter the European Union and European Free Trade Zone countries.
