LoRa Wireless Ultrasonic Water Meter
- SK-UM11 series ultrasonic water meter is developed based on the principle of propagation velocity difference method, and the measurement accuracy is stable.
- Adopt low power design, a battery life length can be 10 years.
- High repeatability, low-pressure loss, no moving parts, accuracy requirements meet GB/778-2007, JJG162 - 2009 verification regulations.
- The starting flow of the ultrasonic water meter is low to 0.002 m³/h。The ultrasonic water meter adopts IP68 waterproof design, which can be immersed in water for a long time.
- The water meter can be installed in many angles, and the measuring accuracy of the water meter is not affected.
- It supports wireless RF( Radio Frequency ) 868MHz output interfaces.
