- Commodity name: High-Precision Electromagnetic Water Meter Dedicated for Trade Settlement
I. Product Introduction

This product is Jiangsu DeGao's seventh-generation electromagnetic water meter—a flagship model designed specifically for large industrial and commercial users, as well as municipal water companies, in the field of trade settlement. "Tailored for the revenue side." Utilizing Faraday's electromagnetic induction as the measurement principle, it employs military-grade dual-frequency excitation and a ultra-low-power SOC algorithm to achieve 1 Level measurement accuracy, R≥400 ultra-wide range ratio ensures "large meters aren’t undercounted, and small meters remain accurate." The entire device features IP68 protection and EMC Class E2 certification, enabling it to operate continuously for over 8 years in harsh environments such as strong electromagnetic fields, high humidity, and underground well chambers—truly delivering maintenance-free performance with zero complaints and zero disputes.

II. Product Specifications

• Nominal diameter: DN40–DN300 (catering to all calibration requirements for trade settlement)

• Measurement accuracy class: Level 1, Level 2

• Measurement range ratio: R ≥ 400 (Q3/Q1)

• Initiation Flow Velocity: 2 mm/s (Nighttime micro-leaks are perceptible)

• Power supply: 3.6 V lithium battery, with an 8-year lifespan (supports Lithium battery / Municipal Electricity /Solar energy seamless switching)

• Communication protocols: Modbus-RTU, NB-IoT/4G full-stack compatible

• Medium temperature: T 3 0 (0- 3 0 ℃), optional T 50

• Protection rating: IP68 (can operate underwater at 2 m for extended periods)

III. Product Features

1. Wide-range adaptability: Dual-frequency excitation + dynamic gain, ensuring linear accuracy of ≤0.2% across the entire Q1-Q4 range; with a range ratio R ≥ 400, the device handles high flows without reaching the upper limit and maintains signal fidelity even at low flow rates.

2. Revolutionary Design of Zero Straight Pipe Section: Patented Flow Field Design +CFD optimization ensures accuracy with 0D front-end and 0D rear-end installation—no need to cut or relocate existing pipes during renovations of aging networks, leading to significant savings. Significantly Construction costs.

3. Financial-grade security: TLS 1.3 encrypted transmission, magnetic attack color indicator—ensuring every cubic meter of data remains tamper-proof and fully traceable.

4. 8-Year Maintenance-Free Operation: The device's static power consumption is ≤100 µA, Battery life More than 8 years.

IV. Product Application Scenarios

1. Industrial and Commercial Trade Settlement: High-value water users such as industrial parks, CBD complexes, star-rated hotels, hospitals, etc., replacing mechanical large-caliber water meters to reduce annual measurement losses. Significantly reduce 。

2. DMA Zone Assessment: As the master table for Level 1 and Level 2 zones, minimum flow resolution during nighttime High , Leakage location error Effectively shorten , helping to reduce leakage rates Significantly reduce 。

3. Secondary Water Pump Room: Equipped with main inlet and outlet pipes for the pump room, along with pressure-boosting devices, this system features real-time flow-pressure interlinkage, enabling on-demand frequency conversion and significantly reducing energy consumption of the pump units.

4. Energy Management Contract (EMC): Centered on metering data, this provides water utilities and energy-saving service providers with precise water consumption benchmarks, ensuring that energy-saving revenue sharing is transparent and equitable.
