LXC Residential Ultrasonic Valve Controlled Water Meter

LXC Residential Ultrasonic Valve Controlled Water Meter

Using ultrasonic metering principle, LXC ultrasonic valve water meter has the advantages of low starting flow, wide range ratio, high precision and long service life. Based on tel- communication technology, this product integrates ultrasonic metering, data storage, valve control,remote communication and local communication. Can be widely used in residential units, buildings and other systems.

Main Advantages

Functional Advantage
  • The water meter have not moving parts, with no mechanical component, low pressure loss, no installation angle requirements.
  • The water meter has valve control function, which can realize remote control of the on-off valve.
  • Range ratio 250,metering every drop of water, the water meter can help with leak detection.
  • Ingress protection is IP68,which makes the water meter can work underwater for the long term.
  • The water meter has a self-learning function, which can adjust the communication frequency according to the signal condition and extend the battery life.
  • The water meter uses Goldcard’s unique patented antenna technology, the signal is stable, and the signal strength is more than 30% stronger than the  common products on the market.
Unique Structure Design
  • The water meter integrates highly sensitive light-sensitive button function for better human-computer interaction.
  • Battery replaceable design for higher reliability.
  • The water meter adopts the all-inclusive pipe section structure to better prevent man-made damage.
Tel-communication Advantage
  • The water meter is connected to the data center through a network to realize remote meter reading, ladder water pricing, and remote valve Control, data analysis, power percentage display, prepaid and other functions.
