产品描述

- Commodity name: Export-Only Electromagnetic Water Meter
I. Product Introduction

The export-oriented dedicated electromagnetic water meter is a next-generation electronic measuring instrument developed specifically for global water trade settlement and zone-based metering applications. Built on the principle of Faraday’s electromagnetic induction, this product features a rectangular flow-channel measuring tube and a fully stainless-steel welded housing—eliminating any moving or obstructive components. As a result, it maintains Class 1 trade-grade accuracy even under extreme installation conditions such as zero straight pipe sections, strong flow disturbances, or submersion scenarios. The entire device has successfully passed multiple international certifications related to drinking water and trade settlement, including MID, OIML R49, NSF61, and FCC standards.

II. Product Specifications

• Caliber range: DN40–DN200

• Accuracy Class: Class 1 (R160, R250) / Class 2 (R160–R400)

• Initial flow rate ≤ 2 mm/s, enabling "drip-by-drip metering"

• Zero straight pipe section: No straight pipe sections are required before or after; it can be directly installed on elbows, tees, and reducers.

• Protection Rating: IP68

• Power supply method: 3.6 V lithium battery with a battery life of ≥ 8 years;

• Output interfaces: RS485 Modbus, 4G/GPRS

• Media temperature: 0.1 – 50 °C (drinking water type) / 0 – 70 °C (industrial type)

• Data storage: Cyclic recording of 36-month daily freeze data and 24-month minute-level data, with no data loss in case of power failure.

III. Product Features

1. Zero Straight Pipe Section

The rectangular flow guide tube, combined with the patented excitation structure, maintains accuracy even under front-to-back 0D installation conditions, eliminating the need to add additional flowmeter wells during pipeline network renovations and significantly reducing project costs.

2. All-Scenario Metering

The flow-obstruction-free design ensures low pressure loss, making it suitable for a wide range of applications—including secondary water pump outlets, gravity flows from elevated water tanks, and nighttime micro-flow leakage monitoring.

3. Full-Range IoT

Built-in eSIM supports 4G Cat-M1 / NB-IoT global bands, enabling seamless cross-border roaming.

4. Long-lasting, Maintenance-Free

Bearingless, impeller-free, and with no risk of electrode fouling; battery life ≥ 8 years.

5. Dual Trade Security

Mechanical lead seals; automatic event recording in case of power failure or magnetic field interference, with tamper-proof events traceable down to the second level.

6. Intelligent Self-Diagnosis

Self-diagnosis of 12 types of faults, including air duct blockage, bubble formation, electrode contamination, and excitation circuit abnormalities, with proactive work order notifications delivered via the IoT platform.

IV. Product Application Scenarios

• Global trade settlement: Providing trade metering services for large industrial and commercial users of water utilities in Europe, the Middle East, and Southeast Asia, meeting the dual certification requirements of MID & OIML for billing purposes.

• Secondary water supply equipment export: Featuring a frequency-controlled secondary water supply unit for export, the zero-straight-pipe design effectively addresses the challenge of limited pump room space.

• Zoning Metering DMA: In areas with dense, older pipeline bends, directly replace mechanical water meters to achieve precise monitoring of nighttime minimum flow rates, significantly reducing leakage rates.

• Irrigation and Water Intake: The battery-powered version is designed for irrigation headworks in farm fields without grid access, as well as remote pumping stations, offering an 8-year battery-life guarantee with no replacements needed.
