Multi-parameter water quality monitor

MetriNet is a multi-parameter water quality monitor to measure network water quality in real time

Product specifications

Product title: Multi-parameter water quality monitor
Brand: ATI

Analytical Technology’s MetriNet multi-parameter water quality monitor for networks is a new approach to smart sensor technology, with amazing capabilities.  It is a modular approach to the distributed collection of water quality data.  Designed specifically for applications in water distribution networks, the MetriNet allows ‘no compromise’ continuous measurement of all the main water quality parameters you need to measure in distribution networks:

  • Residual chlorine (free and combined)
  • Turbidity
  • pH
  • Conductivity
  • Dissolved oxygen
  • Temperature
  • and many more!


At the heart of the system are smart digital sensors, the industry-leading M-Nodes, that come complete with all the communications protocols needed and expected in today’s digital age, as well as a good old-fashioned analogue output.

The M-Nodes are connected to the water supply using a purpose designed ‘click-connect’ flow cell arrangement. Sensors are connected in series to minimize water usage and can run at pressures up to 6 bar. This means that MetriNet systems can be used in closed bypass arrangement to completely eliminate water loss.

M-Nodes are ultra-low-powered and run autonomously for years at a time on small batteries. Alternatively, they can be powered from a local plc or telemetry system. Flexibility really is the name of the game with M-Node sensors, they can be connected to any data gathering system. The modular nature enables users to assemble a monitoring package that fits individual site requrements.

For those of you looking for a complete solution, M-Nodes can be connected to the MetriNet User Interface (MUI). The MUI connects to up to 8 M-Node sensors and connects to the outside world in via any ‘ftp’ based system. The MUI also has on board data -logging with massive data storage capabilities.

M-Nodes are complete water quality monitors equivalent in most respects to full function instruments.  Electronic assemblies are galvanically isolated from both the power supply and communication link.

  • Monitors water quality and collects data at remote locations
  • Can foresee potential issues by advising early, which avoids complaints and allows you to take mitigating action
  • Pro-active network management with measuring points across the whole network
  • Zero and span data stored internally so calibration can be done anywhere
  • Internal clock records total run time on the sensor
  • Calibration timer can alert users when calibration is due
  • Two alarm set points are available
  • Sensor diagnostics report problems in clear message form
  • Controller accepts up to 8 M-Node sensor inputs
  • Stores data at user-defined intervals
  • Stores over 3000k  values
  • Internal Micro-SD RAM card provides data backup in the event of communication problems
