CHINT Water Meters

LXSY intelligent remote valve-controlled cold water meter

1. Product overview Intelligent remote cold water meter is a kind of intelligent water meter that supports various remote

communication technologies. The running data of the intelligent water meter is transmitted to the centralized

reading platform by means of NB- Io T, Bluetooth, LoRa, etc., which can not only realize the monitoring of water

consumption information, but also realize the reading of water consumption and remotely control the on-off

valve of the water meter.

2. Product features ● Long lifetime: large-capacity safe lithium battery, low- power design, service life ≥8 years. ● Super protection class: Multi-layer glue sealing, IP68 dustproof and waterproof, supporting immersion installation. ● High compatibility: optional magnetic or non-magnetic sampling, supporting two-way measurement. ● Remote reading: meter data uploads to CHINT cloud automatically. ● Measurement safety: Adopting independent measurement module and anti-interference algorithm to make sure the stable accurate measurement in complex environment. ● Stable communication: high-gain sheet metal antenna, the success rate of once communication can reach to ≥99%. ● Convenient maintenance: electromechanical separation design with quick disassembly and assembly, with special battery compartment structure design for easy replacement. ● Convenient meter reading: dust-proof and high-permeability PC cover, independent pointer counter, no influence on reading. ● Remote valve control: billing valve control, supporting remote valve opening and closing of data platform. 3.
