Product Description
The ultrasonic water meter is a type of water meter that uses ultrasonic technology to measure water flow. Compared with traditional mechanical water meters, it offers higher accuracy, better durability, and stronger data processing capabilities
Product Features
- Designed with no moving parts to avoid mechanical wear, enhancing product stability and longevity.
- Accurately measures water usage even at low flow rates (4L/h), ensuring reliable data.
- Equipped with a 9-digit LCD, clearly showing total cumulative volume and real-time flow for easy user monitoring.
- Low-power circuit design effectively extends battery life, with an overall service life of up to 8 years.
- Ultrasonic Water Meter supports multiple communication methods, including wired and wireless AMR (Automatic Meter Reading) technologies, facilitating remote data collection and management.
