Product Overview

Description


ultrasonic water meter


1. SK-UM11 series ultrasonic water meter is developed based on the principle of propagation velocity difference method, and the measurement accuracy is stable.


2. Adopt low power design, a battery life length can be 10 years.


3. High repeatability, low pressure loss, no moving parts, accuracy requirements meet 


4. The starting flow rate is low to 0.002 m³/h


5. Support M-BUS or various wireless output, realize remote meter reading, facilitate centralized management of users, and realize intelligent analysis of pipe network data.


6.The ultrasonic water meter adopts IP68 waterproof design, which can be immersed in water for a long time.


7. The water meter can be mounted in many angles, and the measuring accuracy of the water meter is not affected.
