MultiLog LX2

Stand-Alone Communicating Data Logger

The Multilog LX2 range of data loggers are often used for pressure and flow monitoring in drinking water networks, but due to the variety of sensors that can be connected and the measurement processing capabilities, it can be used for many other applications.

These data loggers are equipped with the latest generation of LTE-M/NBIoT cellular modems and offer a 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
  • 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 change of measurement, etc.
    — calculation of minimum, maximum, average values, counting, height/flow conversions, etc...


  • Dimensions (H x W x D): 110 x 150 x 105 mm
  • Weight: 590 g
  • PC-ABS housing
  • Operating Temperatures: -20°C to +60°C
  • Powered by internal batteries and, if desired, external packs
  • Possibility of primary power supply by 12V source (batteries used as backup in this case)
  • IP68 waterproof (submersible)
  • Integrated cellular modem LTE-M/NBIoT
  • Data and alarm transmission through Data IP and backup via SMS
  • Logging capacity: 1 million timestamped data readings
  • Configurable sampling rate (1 sec to 24h), with possible acceleration during alarms
  • Inputs/Outputs available (depending on models):
    — digital ON/OFF inputs (level floats, rain gauges ...)
    — Mono or bi-directional count inputs (up to 25 Hz)
    — analog inputs 4-20mA, 0-10V, 0-1V
    — integrated pressure sensors
    — input for ultrasonic sensor
