Our 3rd generation low-power cellular data logger with a built-in cellular modem for smart water and gas metering.

Automated water meter readings with customizable breakdowns, leak detection and prevention. Detection of water leakages to avoid flooding, non-revenue water for more accurate billing, optimization of operating costs, and improvement of water supply reliability.

Remote data collection via the pulse output (S0) or M-bus. Data is sent through LTE NB-IoT / NB2 / Cat.M1, and LTE450 cellular networks to a central server or HES (Head-end System).

This smart water metering device has a standalone and intermittent operation.

It reads and counts the consumption data (pulse signals or M-Bus data) of the connected meters in „sleep mode” and saves the data to the local storage. Then it wakes up at pre-configured intervals to transmit the stored data using MQTT or LwM2M protocol, plain TCP/IP packets or JSON, XML format.

The device has an IP67 waterproof housing. The installation is easy, which is supported by operation LED lights to indicate proper functioning.

Optionally, add-on boards can be attached to the mainboard to extend the capabilities (e.g. more inputs, M-Bus connection, etc).

The modem has a special internal battery which provides energy for more than 5-10 years.

With the over-the-air (OTA) protocol, the device can be configured and the firmware can be updated remotely without the need to send experts to the field.
