Communication solutions for water metering

  • LoRaWAN long range WAN two-way communication technology
  • Wireless M-Bus short range communication technology for drive-by/walk-by meter reading
  • Sigfox long range WAN two-way communication technology (product development option upon individual request)
  • Bluetooth Low Energy (BLE 5.0) for local
    communication with flow control valve and with smartphone app

ADDRA Ultrasonic water meter is built on a communication platform that supports multiple communication technologies. LoRaWAN long-range communication technology is offered as the main option. For majority of use-case LoRaWAN will satisfy utility needs not only for data collection, but also for management of metering infrastructure, which shall also include disconnection/reconnection or limitation of water supply to consumer for various reasons (non-payment, overuse, leakage of burst).

In specific cases, when LoRaWAN network is not yet available or has some areas without proper coverage, LoRaWAN can be combined together with short-range Wireless M-Bus, which will allow utility to read meters by walk-by/drive by means using special reading handheld reading devices. Both LoRaWAN and Wireless M-Bus communication channels will work simultaneously.

ADDRA communication platform supports Sigfox. This communication solution can be implemented at individual request.

Bluetooth Low Energy (BLE 5.0) is supported by the meter by default and serves the following purposes:

  • allows connectivity to ADDRA shut-off valve to manage water supply;
  • serves as interface between the meter and smartphone/tablet/laptop to enable readings, configuration or firmware change inside the meter for utility personnel;
  • serves as interface between the meter and smartphone application for consumer that enables meter readings, alarms and management of the valve
  • serves as interface between the meter and smartphone application for consumer for STS based prepayment enabling introduction of tokens, reading of consumption, alarms and remaining credit.
Ultrasonic water meter

The ADD Grup ultrasonic water meter is designed for household water consumption measurement. The installation of this device is quick and simple, and it is known for its high reliability and accuracy. The advantage of this equipment is that it has no moving parts, which means that the ADDRA water meter requires no maintenance, maintains measurement accuracy, and does not need recalibration throughout its service life.

This water meter has a low starting flow, only 1 liter per hour, and it automatically records water consumption data, ensuring reliable data storage. The user-friendly LCD display shows information about the total water usage, alerts to potential leaks, backflows, and provides other useful information.

Furthermore, ADDRA is equipped with various communication interfaces for local access via a smartphone, tablet, or computer, for communication with a valve, and communication channels for remote access, making it an economically advantageous solution. It also complies with international quality and safety standards.

Our water meter supports credit/prepaid operation modes, with prepaid functionality based on the STS standard. For prepaid functionality, it is necessary to separately purchase the ADDRA valve, which interacts with the meter through a BLE interface.
