Product Description

I. Product Introduction

The R500 electromagnetic water meter is a highly precise measurement tool specifically developed by Jiangsu DeGao IoT Technology Co., Ltd. for "District Metered Area (DMA) Leak Control" applications, built on the company’s seventh-generation electromagnetic measurement platform. Leveraging Faraday’s law of electromagnetic induction and incorporating a "dual-frequency excitation + adaptive gain" algorithm, this advanced meter boosts the traditional electromagnetic water meter’s flow range ratio to an impressive R500 (Q3/Q1 = 500:1), while maintaining Class 1 measurement accuracy. At its core, the device features a "low-power SoC chip combined with a sophisticated core filtering algorithm," complemented by an IP68-rated, fully encapsulated stainless steel sensor. This design enables the meter to operate continuously for over eight years without maintenance—even in harsh environments such as underground installations, pump rooms, or outdoor settings—from -20°C to 60°C—providing water utilities with a reliable, long-lasting leak-control solution that delivers "install once, manage for a decade."

3. Product Features

1. Ultra-wide measurement range—no leak goes unnoticed

• A flow range ratio of R500 with a starting flow rate of 2 mm/s, enabling "no volume loss at high flows and accurate measurement of nighttime drips."

2. Ultra-low power, long lifespan

• The device’s static power consumption is ≤100 µA, ensuring over 8 years of battery-free operation.

3. Zero Straight Pipe Sections + All-Scenario Installation

• Utilizing flow field rectification combined with digital compensation technology, it eliminates the need for upstream and downstream straight pipe sections and can be directly installed next to the valve.

4. Full-Chain Interference Resistance

The circuit board is designed with multiple "elevated" layers, equipped with shielding covers, ensuring that signal and power lines run separately without interfering with each other.

Built-in magnetic sensor immediately triggers an alarm and records the event as soon as a strong magnetic field appears nearby (e.g., from a large magnet), preventing anyone from cheating using a magnet.

4. Product Application Scenarios

1. DMA Level-1 / Level-2 Zone Metering

• Deployed in bulk at three-level nodes—pipeline inlet, community master meter, and building riser—to establish a "total-branch-household" water balance model.

2. Secondary Water Pump Room

- Pump house features dual-metering for inlet and outlet water, combined with pressure monitoring, enabling real-time assessment of pump unit efficiency and pipeline leakage. Paired with variable-frequency control, this setup delivers significant energy savings.

3. Trade Settlement for Large Commercial and Industrial Users

• For scenarios with significant daily and nightly traffic variations—such as hotels, hospitals, and factories—this single meter covers a load range of 0.5% to 100%, eliminating the need for "parallel connection of large and small meters" and substantially reducing investment costs.

4. Rural Water Supply and Integrated Urban-Rural Development

• Solar-powered and lithium-battery version addresses the challenge of lacking grid electricity in remote villages and towns; NB-IoT remote transmission enables county-level platform monitoring with a single, comprehensive overview, significantly reducing leakage and losses.
