Multilog 2 WW

Multilog 2 WW

Multilog 2 WW is a highly-versatile data logger, specifically designed to be compatible with a wide variety of HWM and third-party sensors including: RavenEye, MicroFlow-i, dBi or VEGAPULS.

Equipped with our advanced modem, Multilog 2 WW is capable of connecting via LTE-M or NBIoT with a 2G fallback or through 3G or 2G for dependable data telemetry and future-proofing in the rapidly evolving cellular landscape.

Housed in a robust IP68 plastic enclosure, the unit offers multiple inputs and switch outputs and is ideally suited to installation in environments where corrosion is a concern. Multilog 2 WW is a highly versatile solution for waste water monitoring applications where ATEX certification is not required.



With multiple input capability, Multilog 2 WW is a highly effective, battery powered data logging/RTU solution.  Typical applications include:

  • Level, Velocity and Flow monitoring
  • Water Quality Monitoring
  • Control Outputs for third-party systems (e.g. water sampler)
  • Modbus and SDI12 sensor telemetry
  • External power options

Ideal for environmental and waste applications where ATEX certification is not required.
