Certification standards for water meter seals

ISO 9001: Quality Management System Certification, ensuring that high quality management standards are followed in the manufacture of seals.

NSF/ANSI 61: The National Sanitation Foundation (NSF) and the American National Standards Institute (ANSI) together issued the NSF/ANSI 61 certification standard. Used to evaluate the sanitary safety of materials and products that come into contact with drinking water.

WRAS (Water Regulations Advisory Scheme): WRAS (Water Regulations Advisory Scheme) is a UK certification scheme used to examine the sanitary safety and compliance of drinking water system items.

KTW: The German Federal Office for Health and Environment (UBA) has created a certification standard to evaluate the sanitary safety of materials in contact with drinking water.

ACS (Attestation de Conformité Sanitaire): ACS (Attestation de Conformité Sanitaire) is a French certification standard used to assess the sanitary safety and compliance of materials and products that come into contact with drinking water.

CSA B137.5: CSA B137.5 is a certification standard established by the Canadian Standards Association (CSA) for evaluating the performance and compliance of water supply system pipes, fittings, and seals.

Introduce

Water meter seals, as the name implies, are rubber seals used for water meter connection interfaces. They are typically composed of high-quality EPDM materials and may offer consistent sealing in water meter connection interfaces. It has an annular shape that is hollow on the inside and spherical on the exterior, this structure may be readily fitted into the water meter connection interface.

Advantage

Water meter seals are crucial for preventing water leakage, filling gaps, and ensuring equipment operation.

Improve reading accuracy and precision: By forming a rotating seal structure between the sealing block and the groove at the bottom of the letter wheel box, the sealing performance can be increased to avoid moisture penetration, thereby improving the accuracy and precision of water meter readings.
Waterproof and moisture-proof performance: The smart water meter uses high-performance sealing materials that can fit tightly to the shell to form a reliable sealing barrier that effectively prevents water penetration and other liquids.
