LoRaWAN Ultrasonic Valve Controlled Water meter

LoRaWAN Ultrasonic Valve Controlled Water meter

HKT LORA's LoRaWAN water meters fully comply with the LoRaWAN standard protocol established by the LoRa Alliance, ensuring seamless interoperability with mainstream gateways and network servers.

Our ultrasonic LoRaWAN water meters feature advanced metering technology with anti-clogging and anti-interference from metal impurities. Ultrasonic metering is highly sensitive to minimal flow rates, effectively detecting tiny leaks and drips that traditional mechanical meters cannot measure. With an all-electronic design, there is no mechanical wear over time — ensuring long-term measurement accuracy. The meters support remote meter reading and remote valve control, offering long transmission range, low power consumption, extended lifespan, and cost efficiency — enabling low-cost, high-benefit automated management.

Additionally, HKT LORA provides a complete water metering solution — beyond the smart meters, we also offer LoRaWAN gateways and a cloud-based management platform (the LoRaWAN ultrasonic water meter management system), delivering end-to-end seamless integration to ensure rapid deployment while reducing operational and maintenance costs.

Features

• Connectivity

This product supports multiple communication protocols including LoRaWAN, NB-IoT, WiFi, GPRS, M-BUS, and RS485. LoRaWAN frequency bands are available in 433~510MHz or 863~928MHz to meet regional regulations and deployment needs worldwide.

• Range & Power Efficiency

Our LoRaWAN smart ultrasonic water meter supports dual antenna options (built-in/external), ensuring flexible signal coverage and a maximum line-of-sight range of 15km; ultra-low-power design with standby current as low as 15μA guarantees stable data transmission and extended battery life even in large-scale deployments.

• Closed‑Loop Management System

HKT LORA provides a complete closed-loop management system: the meter periodically sends cumulative flow and battery data to nearby LoRaWAN gateways, which forward it to the cloud platform. Administrators can check real-time readings of all meters from the management system — no on-site visits required.

When a user's balance is overdue or settled, the administrator can remotely close or open the valve. If the meter detects an abnormality — like a leak or valve failure — it reports it automatically, so operators can act fast and cut water loss.

• Local O&M & Data

The meter supports cumulative flow measurement, with metering data and remaining battery capacity automatically uploaded to the cloud server and refreshed regularly — eliminating manual meter reading. Data history is stored locally to prevent loss during network interruptions and is automatically re‑uploaded once connectivity is restored. The LCD screen displays battery level, water balance, valve status, and other key information at a glance during on‑site inspections, while low‑battery and valve‑failure alarms proactively notify operators of abnormal conditions.
