AI-Powered supplier vetting

SummaryNINGBO XINGHANG METER TECHNOLOGY CO., LTD. is identified as a Chinese manufacturer/factory specializing in water meters and heat meters. The supplier reports more than 20 years of manufacturing experience, exports to over 60 countries, and derives 90% of total sales from exports. Its stated capabilities include electronic and mechanical design, programming, testing, calibration, three production lines, 11–20 quality-control staff, and 21–30 years of total R&D engineer experience. ISO 9001, ISO 14001, ISO 14000, and ISO 14064 are listed as management-system certifications. Reported annual water-meter production is 1.2 million pieces, with one-month lead times in both off-peak and peak seasons. Evidence supports established manufacturing, international distribution, and engineering capabilities. However, the provided information does not sufficiently verify financial strength, customization services, or named customer cases.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and operates as a limited company in Zhejiang, China, with Instruments & Meters as its commercial trade category. This directly supports its status as a manufacturing supplier rather than only a trading intermediary.

CertificationsThe supplier lists ISO 9001, ISO 14001, ISO 14000, and ISO 14064 as its supplier management-system certifications. These stated certifications provide explicit evidence of formal quality and environmental management systems, although certificate scope and validity details are not provided.

After-Sales capabilityThe supplier states that it provides efficient after-sales service and describes this capability alongside professional engineers and advanced technology. This is positive direct evidence, but the slices do not specify service locations, response times, warranty terms, or support procedures.

R&D capabilityThe supplier reports an engineering team capable of designing electronic parts, programming code, mechanical structures, testing, and calibration. Its product range includes mechanical, magnetic, ultrasonic, smart, modular, volumetric, water, and heat-meter products, supporting established technical breadth and product-development capability.

Production capacityThe supplier reports more than 20 years of water- and heat-meter manufacturing, three production lines, 11–20 quality-control staff, annual water-meter output of 1.2 million pieces, and one-month order fulfillment in both peak and off-peak seasons. It also states that 90% of sales are exports and identifies broad international markets, indicating substantial production and delivery experience.

Product Q&A

Q:What metering standards and accuracy class does this large-diameter ultrasonic heat meter comply with?

It meets EN1434 and CJ128-2007 standards with Class 2 accuracy and R25 measuring range ratio, fully satisfying the trade settlement and network management requirements of district heating utilities.

Q:What diameter range is available for district heating pipeline networks?

This series covers DN50 to DN500 with standard flange connection, matching the common specifications of main and branch district heating pipelines.

Q:What communication interfaces are supported for AMI/AMR system integration?

It provides both wired and wireless options: M-BUS, RS-485, pulse output, LoRa/LoRaWAN and NB-IoT, enabling seamless connection to centralized energy management systems.

Q:What is the battery performance and protection level for long-term outdoor operation?

It is equipped with an ER18505 waterproof lithium battery with 10-year service life, and achieves IP68 protection class, adapting to long-term outdoor and underground pipeline operation.

Q:How long can historical data be stored, and is there power-off protection?
