Import Big Diameter Smart Water Meter — Buy in Bulk from Supplier in China

This big diameter smart water meter from Chongqing Smart Water Meter Group Co., Ltd. is a vertical Waltmann remote-reading meter available in sizes LXY80, 100, 150, 200, and 500, covering nominal diameters from 80 mm to 500 mm. The integrated smart technology enables real-time data collection and remote monitoring without manual site visits, addressing utility needs for large-flow measurement in municipal, industrial, and large residential applications. Construction emphasises durability for outdoor and buried installations where environmental exposure and continuous operation are expected.

The Waltmann impeller principle, also known as the Woltman or turbine type, uses a helical rotor aligned with flow direction to measure volumetric throughput with minimal pressure loss. For large-diameter meters, this mechanical approach remains cost-effective against electromagnetic alternatives while providing accuracy classes typically within +/- 2% in the lower flow range and +/- 1% in the permanent flow range per ISO 4064 or OIML R49 standards. The remote reading module converts mechanical rotation into electronic pulses or encoded data, transmitted via wired M-Bus, wireless RF, or GPRS depending on configuration. Robust housing materials, typically ductile iron or cast iron with epoxy coating, protect internal components against corrosion and mechanical damage in harsh environments.

Primary buyers include municipal water utilities managing district metering areas, industrial facilities monitoring process water or cooling circuits, and property managers of large residential complexes requiring sub-metering or main inlet measurement. The energy-efficient design supports battery-powered operation with multi-year cell life, reducing infrastructure requirements. When sourcing from Chongqing Smart Water Meter Group Co., Ltd., buyers should confirm accuracy class certification, communication protocol compatibility with existing AMR/AMI systems, pressure rating, and environmental protection level. Installation orientation, straight pipe requirements, and flange standards must also be verified to ensure hydraulic performance and mechanical fit.

Chongqing Smart Water Meter Group Co., Ltd. is headquartered at No.2 Longhua Road, Jiulongpo District, Chongqing 400052, China. The company holds imported-tier supplier status with a harbor trust designation on this platform. The response rate is recorded at 0.00% with zero average response hours, indicating no historical communication data is available through this channel. Buyers should establish direct contact to evaluate technical support responsiveness, after-sales service capability, and project engineering assistance before committing to volume orders.

The supplier profile does not disclose founding year, employee count, annual production capacity, installed base, or specific client references. No ISO 9001, ISO 14001, or product-specific certifications are confirmed in the available data, though these are commonly claimed in the water meter industry. The company specialises in smart water metering solutions, with this product line targeting large-diameter applications where remote data collection reduces operational costs. Given the absence of verified response signals, buyers should request factory audit reports, calibration laboratory accreditation, and reference installations of similar scale. Direct verification of quality management systems and field reliability data is essential for infrastructure investments with 15-20 year service life expectations.
