Products Description
The hot water meter is a state-of-the-art ultrasonic water meter designed for residential applications. Utilizing advanced ultrasonic measurement technology, it ensures high-precision metering while minimizing water loss and improving utility efficiency. Equipped with intelligent wireless communication and real-time data analysis, this meter enhances water management by reducing non-revenue water and optimizing resource allocation.
Built with a durable, wear-resistant structure, it features no moving mechanical parts, ensuring long-term accuracy and maintenance-free operation. The combination of high-strength engineering plastics and corrosion-resistant brass extends its service life to up to 12 years, far surpassing traditional mechanical meters. Its robust, pressure-resistant design guarantees reliable performance even in demanding conditions.

Main Features

1. Accurate traffic coverage range (R400): Dynamic range adaptation ensures consistent accuracy under all traffic conditions.
2. Universal pipeline compatibility (U0/D0): It can be easily installed without modifying the pipeline, reducing implementation costs.
3. High sensitivity to microflow (10L/h): Accurately detect the minimum water consumption and eliminate measurement gaps.
4. Strong anti-interference performance: not affected by water impurities or external magnetic fields, maintaining reliable measurements.
5. Extend the service life by 12 years: Abandoning traditional instruments and minimizing replacement and maintenance costs.
6. Multiple installation options: Supports vertical and horizontal installation without adjustment.
7. Real water flow measurement mode: automatically filters out air interference to obtain accurate consumption data.
8. IP68 full environmental protection: perfect operation under high dust and high humidity conditions.
