Product Description

1. Product Overview:
LXS NB-loT smart water meter adopts mechanical base meter. According to the customer's needs can be matched with magnetic/no magnetic/dry/wet and other schemes, which inte grates data storage, remote communication and local com munication, and has the advantages of ultra-low power consumption, high accuracy, high reliability and high stability. It can be widely used in residential units, buildings and other systems.

2. Main Advantages:

• Range ratiois selectable at R80~R160.
• Ultra low power consumptionensures 8-vear service life on the basis of communication once a day.
• The electronic part and the base meter part are separated and can be easily disassembled.
• Infrared and button functions, better user experience.
• Protection level up to lP68, it can work under water for a long time.
• With sheet metalantenna to improve signal strength.
• Adjust the communication frequency according to the sign al condition to extend the battery life.
• It is connected to background data center through NB-loT for remote meter reading, ladder water price, data analysis, and percentage display of electricity, prepayment and other functions.
