LXC Residential Ultrasonic Water Meter

LXC Residential Ultrasonic Water Meter

The LXC residential ultrasonic water meter utilizes the transit-time difference method. By measuring the time difference of ultrasonic waves propagating downstream and upstream within the liquid, it determines the average liquid flow velocity in the channel and calculates

the liquid flow volume accordingly. The meter offers key advantages of low starting flow, wide range ratio, high accuracy, high stability and long service life. And it can be widely used in residential scenarios such as individual households, apartments and building complexes.

Main Advantages

Performance Advantages
  • No moving parts, ensuring no mechanical wear, low pressure loss and no installation angle restrictions.
  • Wide range ratio of up to R250, capable of drip water metering and leakage detection.
  • IP68 protection, enabling long-term underwater operation.
  • Self-learning function, with adaptive communication frequency adjustment based on the signal conditions to extend battery life.
  • Goldcard’s unique patented antenna technology ensures stable communication, with signal strengthover 30% higher than that of typical products on the market.
Structural Advantages
  • Integrated high-sensitivity photosensitive button for better human-computer interaction.
  • Full-wrap pipe section structure for improved protection against intentional damage.
Communication Advantages-Wireless Remote Transmission
  • Connect to the backend data center through NB-IoT and other networks to realize functions such as remote meter reading, tiered water pricing, data analysis, percentage display of electricity consumption, and prepaid payment.
