BIS Certification for Water Meters (bulk Type) IS 2373:1981

BIS Certification is a mandatory for Water Meters (bulk Type) As Per IS 2373:1981. Bulk metres are a vital tool in modern water management systems, designed to detect leaks in large-scale plumbing infrastructure, such as those supplying water to extensive residential complexes. These meters are installed only to monitor water flow and do not affect billing, ensuring that residents are accurately charged based on their individual consumption.

In India, the importance of maintaining the quality and accuracy of these meters is underscored by the Bureau of Indian Standards (BIS) through its certification process, specifically under IS 2373:1981. This standard provides guidelines for bulk type water meters, ensuring they meet stringent requirements to prevent water wastage and guarantee fair billing practices.

IS 2373:1981

Water management is critical to sustainable development, making accurate measurement essential in scenarios involving large volumes of water. Bulk water meters play an indispensable role here. IS 2373:1981 specifies standards for two types of bulk water meters: vane-wheel (impeller) type, ranging from 50 to 300 mm, and helical type, ranging from 50 to 500 mm. These meters must be manufactured from corrosion-resistant, non-toxic and non-staining materials to ensure long-term durability and safety.

Timeline for BIS Certification for Water Meters (bulk Type)

The approximate timeline to obtain BIS certification for Water Meters (bulk Type) to use the ISI mark as per IS 2373:1981 is as follows:

For Indian Manufacturers (Standard Timeframe – 30 days)
For Foreign Manufacturers (Standard Timeframe – 180 days)

Conclusion:

The standard mandates that the internal components of the meter, especially those in constant contact with water, be protected from corrosion, avoiding the use of dissimilar metals in contact under water to minimize electrolytic corrosion. Additionally, the meters must be equipped with flanges at both ends, be machined flat to ensure proper fitting without protruding joint faces, and be able to handle water temperatures up to 45ºC and pressures up to 1.6 MPa (16 kgf/cm2).

Accuracy in measurement is a critical feature, as per IS 2373:1981 the metering precision for both types of meters should be within ±2 percent. This stringent accuracy ensures that water consumption is reliably tracked on a large scale, aiding in effective water resource management and leakage detection, ultimately contributing to conservation efforts and efficient use of this vital resource.
