MetriNet combines Multilog 2, our market leading telemetry logger with ATi's pioneering multi-parameter system to deliver real-time water quality data.

MetriNet uses a series of smart digital sensors to continually measure a range of water quality parameters including residual chlorine, turbidity, pH, conductivity, dissolved oxygen and more.



At the heart of the MetriNet system are ATi's new M-nodes series of smart digital sensors.  M-nodes are connected to the water supply using a purpose designed flow cell arrangement and can operate up to pressures 6 bar.

Multilog 2 is a highly advanced and versatile multi-channel data logger designed to monitor any combination of digital and analogue signals.

As well as a wide variety of water quality parameters, the combination of MetriNet and Multilog 2 has the capability to measure pressure, flow and pressure transient.


Key Features and Benefits

  • Interchangeable M-nodes: wide variety of water quality parameters available
  • Sensors connected in series: can be used in closed bypass arrangement to completely eliminate water loss
  • Ultra low-powered: M-nodes run autonomously for years on small batteries 
  • Multiple sampling rates: user-selectable to minimise power consumption
  • Telemetry: NBIoT LTE-based cellular communication standard with fallback 2G capability
  • Serial input options: for connection to digital meters, SonicSens level sensor, Modbus, SDI12, RS232, Badger/Sensus/Neptune serial meter interfaces
  • 4 channel logging: 8 or 16 channels available on request
  • Fast logging: primary logging to 1 second as standard - 25hz for transient events
  • Alarm: full alarm functionality
  • Robust: rugged die case aluminium case
