BIS Certification Consultant for Bulk Type Water Meters | IS 2373:1981 | Qualitance India
Introduction
Bulk Type Water Meters are used to measure water flow in water-supply systems, including public and private distribution networks. Accurate measurement is important for monitoring water consumption, managing distribution and supporting reliable billing and water-management operations.
The relevant Indian Standard is
IS 2373:1981 – Water Meters (Bulk Type) — Specification (Third Revision). The standard covers vane-wheel (impeller-type) water meters from 50 mm to 300 mm and helical-type water meters from 50 mm to 500 mm. <Cite refs={["turn549674search22","turn549674search23"]}/>
Manufacturers seeking BIS certification need to understand the applicable standard, product testing requirements, factory quality-control arrangements, documentation and licence-scope conditions.
Qualitance India provides consultancy support to manufacturers navigating BIS product certification and related compliance requirements.
What Is IS 2373:1981?
IS 2373:1981 specifies requirements for bulk-type water meters. It covers two principal designs:
- Vane-wheel or impeller type: A meter in which the runner or impeller is mounted on a vertical spindle and has vanes arranged around its axis.
- Helical type: An axial-flow meter whose runner has vanes forming a multi-threaded helix.
The standard identifies nominal sizes ranging from 50 mm to 500 mm, depending on the meter type. <Cite refs={["turn549674search22","turn549674search8"]}/>
Manufacturers should verify the exact product configuration, size and type against the applicable edition of the standard and its amendments before preparing a BIS application.
Is BIS Certification Mandatory for Bulk Type Water Meters?
Yes. Bulk Type Water Meters are included in the
Water Meters and Accessories (Quality Control) Order, 2023, notified through Gazette notification S.O. 1142(E), dated 5 March 2024. The order lists IS 2373:1981 for Water Meters (Bulk Type), and BIS lists this product under Scheme-I, the ISI Mark Scheme. <Cite refs={["turn549674search24","turn549674search4"]}/>
The order provides for implementation dates based on the applicable category of enterprise. Manufacturers should review the original Gazette notification and subsequent amendments to confirm the requirements and any exemptions applicable to their circumstances.
Where the QCO applies, the product must comply with the applicable Indian Standard and bear the BIS Standard Mark under a valid licence. A consultant cannot issue a BIS licence or guarantee its approval.
BIS Certification Process for Bulk Type Water Meters
BIS has published a product manual for Water Meters (Bulk Type) under IS 2373:1981. The manual provides guidance on product sampling, grouping, test equipment, the Scheme of Inspection and Testing, and the scope of the licence. <Cite refs={["turn549674search21","turn549674search0"]}/>
1. Identify the Product Type and Size
Determine whether the meter is vane-wheel (impeller type) or helical type. Confirm the nominal size, dial type and any applicable frost-protection feature.
2. Review Product Design and Materials
Review the construction, components, material specifications and manufacturing arrangements against the requirements of IS 2373:1981. Keep supporting technical documentation and supplier records available.
3. Prepare Manufacturing and Quality-Control Documents
Document the manufacturing process, inspection stages, testing arrangements and responsibilities of quality-control personnel. Ensure that the factory can demonstrate how product conformity is maintained.
4. Arrange Testing
Identify the tests required under the standard and review the current BIS product manual for sampling and test-equipment requirements. Testing arrangements should cover the applicable performance and construction requirements.
5. Submit the BIS Application
Prepare the application and supporting documents using the applicable BIS process. Ensure that applicant details, factory information and the proposed licence scope are consistent.
6. Complete the Applicable Assessment
Address any documentation gaps or observations raised during the certification process. The manufacturer should be prepared to demonstrate the relevant manufacturing and testing capabilities.
7. Obtain the Licence Before Using the ISI Mark
The manufacturer may use the BIS Standard Mark only after the relevant licence has been granted and in accordance with its scope and conditions. Product type, size and dial configuration should match the approved licence scope.
