1. Measuring Instruments CE Certification (MID)

Measuring Instruments CE Certification (MID) is a certification implemented in accordance with the EU Measuring Instruments Directive (MID, 2004/22/EC), aimed at regulating the EU single market for measuring instruments, eliminating trade barriers, and protecting consumer rights. The specific explanation for the delay is as follows:

1. Overview of the Directive Issuance and Implementation: The European Union officially notified the MID Directive on April 30, 2004, and enforced it from October 30, 2006. Purpose: To establish a single market for measuring instruments for manufacturers, enabling products to be universally used throughout Europe and ultimately benefiting consumers. Scope: Covering ten types of measuring instruments, including automatic scales, fuel dispensers, length and volume measuring instruments, water meters, electricity meters, gas meters, etc. Secondly, the purpose of certification is to regulate the market: to eliminate trade barriers within the European Union and promote the free circulation of measuring instruments. Protecting consumers: ensuring the accuracy and reliability of measuring instruments, and safeguarding consumer rights. Regulatory status: MID is not only an important application of metrology, but also an important regulation for the qualification assessment of metrology products.

III. Types of Measuring Instruments Covered: Water Meter, Gas Meter, Electricity Meter, Heat Meter, Liquid Meter (excluding water), Automatic Weighing Instrument, Taxi Pricing Instrument, Material Measuring Instrument, Multi Dimensional Measuring Instrument, Exhaust Gas Measuring Instrument

IV. Requirements and Scope of Application:

Measuring instruments are used for public interests, health, safety, order, environmental protection, consumer protection, travel, taxation, tariffs, etc., and are generally required to comply with MID requirements.

. Key specifications: MID mainly regulates measuring instruments such as water meters, gas meters, electricity meters, heat meters, liquid meters (excluding water), automatic weighing equipment, meters, material measuring instruments, space measuring instruments, exhaust analysis instruments, etc. Qualification assessment mode: Different measuring instruments correspond to different CE modes and MID appendices, such as water meters corresponding to B+F, B+D, H1 modes and MI-001 appendices.

Fifth, Design and Manufacturing Pattern Pattern A: DoC based on internal production management (A1=+product testing by designated institutions).

. Mode B: The designated institutions type inspection mode. Mode G: DoC mode based on the certification of a single product by a designated organization. Mode H: DoC based on a comprehensive quality assurance system (A1=+product testing by designated institutions). Mode C: DoC based on internal production management (C1=+product testing by designated institutions). Mode D: DoC based on QA production process (D1=DoC based on production process). Mode E: DoC based on QA final product inspection and testing (E1=DoC based on QA final product inspection and testing). Mode F: DoC based on product certification from a designated organization (A1=DoC based on product certification from a designated organization). 6、 Related gas meter standards: such as EN 1359:1998 "Gas meters - Diaphragm gas meters" and its revised version. Heat meter standards: such as EN 1434-1:2007 "H
