LXCY ultrasonic cold water meter
1. Product overview Ultrasonic cold water meter is an intelligent water meter based on ultrasonic metering technology, which has high
metering accuracy, wide measuring range, no mechanical wear, stable and reliable long-term use, supports a
variety of Internet of Things communication methods, and can realize water information monitoring and water
consumption reading.
2. Product features ● High range ratio up to R400 ● Multi-layer glue sealing, IP68 dustproof and waterproof, supporting immersion installation. ● Adopt advanced patented flow measurement method and intelligent data error correction technology to ensure accurate and stable measurement. ● Support multiple communication modes: NB-IoT, LoRaWAN, M-BUS, RS485. ● Self-diagnosis function: flow sensor error alarm, temperature sensor error alarm, battery undervoltage alarm. ● Large-capacity safe lithium battery with service can reach to ≥8 years. ● Support reverse measurement ● Optional external power supply (used when configuring 485, specified when ordering)
