overview
Residential Meters are cutting-edge solutions designed specifically for commercial energy management. It utilizes the latest technological advancements, integrating intelligent wireless connectivity, complex data analysis, and excellent measurement accuracy. This combination enables businesses to optimize energy consumption, minimize energy losses, and maximize cost savings. Its innovative design has a durable structure, extending the service life of the electric water meter to 12 years, far exceeding traditional commercial electric water meters. It has no moving parts, ensuring consistent and reliable accuracy while eliminating maintenance needs throughout its entire lifespan. It is made of high-end imported engineering materials known for their excellent strength and pressure resistance, capable of withstanding a maximum allowable pressure of 16 bar, ensuring stable performance in various commercial environments, from bustling office buildings to large industrial parks.
Key Technical Features
1. Multiple measurement ranges: Customize the flowmeter according to your needs through the dynamic range selection of R250, R400, and R500, ensuring accurate readings over a wide range of flow rates.
2. U0/D0 Integration: Seamless collaboration with U0/D0 systems. This compatibility enables direct and accurate measurement, eliminating the hassle of additional pipeline installation.
3. Ultra sensitive detection: capable of detecting flow rates as low as 1.5L/h, capturing the smallest amount of water usage and providing detailed and accurate usage insights.
4. Worry free maintenance: Due to its non mechanical design without moving parts, plastic water meters have wear resistance. This means minimal maintenance, fewer inspections, and significant long-term cost savings.
5. Extended service life: This instrument is durable and is expected to have a service life of 12 years or longer. Its durability reduces replacement frequency, improves reliability, and lowers overall costs.
6. Flexible installation: It is easy to install both vertically and horizontally. This adaptability makes it very suitable for various pipeline settings and simplifies the installation process.
7. No air accuracy: Only measure water flow, ignoring air inside the pipeline. This ensures that the recorded data accurately reflects the actual water usage and provides reliable measurement results.
8. Durable protection: This instrument has an IP68 protection level, is highly dust-proof, and can withstand harsh conditions. Even in the most challenging environments, it can provide reliable performance.
9. Intelligent data processing: equipped with data recording function, the water meter records and stores water usage information. Analyzing these data can help identify consumption trends and optimize water resource management methods.
