The ultrasonic water meter is a new-generation smart water metering device designed for precise measurement without the need for mechanical moving parts. Using advanced ultrasonic transit-time technology, it ensures stable performance, long life, and excellent accuracy even under low flow conditions. Shengda Water Meter provides residential (DN15–DN25) and bulk ultrasonic water meters (DN40–DN300), supporting remote reading and smart AMI/AMR systems.
Key Features & Advantages
1.No moving parts – No wear, stable accuracy for 10–15 years.
2.High accuracy – Up to R250–R500, especially strong in low-flow leak detection.
3.Low starting flow– Perfect for DMA (District Metering Area) leakage control.
4.Multiple communication options – LoRaWAN, NB-IoT, 4G, RS485, M-Bus.
5.IP68 waterproof design – Suitable for underground installation.
6.Long battery life6–10 years depending on model and communication mode.
7.Wide measuring range – Suitable for both domestic and industrial applications.
8.Supports prepaid smart control– Optional valve control for prepaid systems.
