MultiLog 2

Multichannel Communicating Stand-Alone Data Logger

The range of Multilog 2 data loggers offers a wide variety of possible applications, thanks to the numerous types of connectable sensors. They can manage up to 16 measurement channels.

These data loggers are equipped with the latest generation of LTE-M/NBIoT cellular modems and offer great autonomy due to their internal batteries.


  • Monitoring of distribution pressures and flows for water systems
  • Counting (counter signals or flow meters)
  • Sectorization of networks and leak detection
  • Monitoring of river levels and flood risk
  • Monitoring of flows for sewerage networks or rivers (see Multilog 2 Raven-Eye)
  • Physico-chemical quality monitoring (see Multilog 2 Metrinet)
  • Numerous other applications depending on the connected sensors

Main benefits

  • Works on the new LTE-M/NBIoT cellular networks that offers:
    — Better communication in difficult locations (e.g., manholes under the road)
    — reduced energy consumption
  • Flexibility to adapt to a wide variety of applications
  • Long battery life (ranging from 3 years to more than 5 years for most applications)
  • Availability of external battery packs to increase this duration
  • Waterproof IP68 (Submersible), stainless steel 316 connectors
  • High level of security of communications, with SMS backup in case of reduced availability on the Data IP channel of the networks.
  • Configurable remotely
  • Advanced measurement, processing and alarm management functions. Examples of advanced functions:
    — acceleration of measurements and transmission frequencies during alarms
    Alert for ON/OFF status, for threshold, for measurement variation, etc.
    — calculation of minimum, maximum, average values..., counts, height/flow conversions...
