Description
Overview:
The Asset Track Pro Smart Ultrasonic Water Meter uses advanced ultrasonic transit-time technology for highly accurate flow measurement, capable of detecting flow as low as 0.01 m³/h, compliant with OIML R49/MID standards. It features micro-power technology with an 8+ year battery life (ER26500, customizable to ER34615), compact size, strong anti-interference, and stable performance. It supports multi-angle installation without affecting accuracy or causing pressure loss. Ideal for residential use, it includes LoRa connectivity and can integrate with a wireless monitoring system via GSM or Ethernet for real-time data and abnormality alerts.
