LXC Ultrasonic Water Meter

LXC Ultrasonic Water Meter

Goldcard smart ultrasonic water meter integrates metering, data collection, storage, communication, and valve control. Featuring ultrasonic technology and a modular communication design, it supports multi-stage valve regulation while delivering high accuracy, fast response, low power consumption, and long-term stability in a compact form factor.

Main Advantages

Functional Advantage
  • High-precision ultrasonic measurement, accuracy class2, stable and reliable.
  • Supports remote valve control with 5-level opening adjustment(0%, 25%, 50%, 75%, 100%).
  • Built-in water temperature sensor, pressure sensor.
  • Comprehensive alarm system: reverse installation,over-flow, abnormal flow, etc.
  • Battery life exceeds 10 years or even longer. (depending on different operating conditions)
  • Large datastorage, including daily, monthly, and annual consumption.
Unique Structure Design
  • Communication module is replaceable. Easy network switching & convenient on-site maintenance.
  • The water meter integrates photosensitive button function for better human-computer interaction.
  • IP68waterproof and dustproof, strong environmental adaptability.
Telecommunication Advantage
  • The water meter is connected to the data center through a network to support prepayment and other functions.
  • Remote data communication: NB IOT/4G
