Multi-parameter smart water quality monitoring

ATi’s MetriNet solutions are a pioneering, field-proven breakthrough in water quality monitoring. With 16 parameters to choose from, the modular nature allows unique monitoring solutions for individual site requirements across utilities, food & drink, industrial, healthcare, leisure and events.

Available as both street level and below ground installations, MetriNet’s smart sensor technology offers sustainable solutions with zero water wastage*, helping to meet environmental targets, drive down complaints and create real-time awareness of water quality throughout the network. By using actionable insights, MetriNet ensures the efficient delivery of high-quality water in an environmentally friendly way.

Deploying a neural network of MetriNet’s digital smart M-Node sensors at critical locations throughout the water distribution system offers customers continuous, real-time assurances and evidence-based proof that the water is safe. MetriNet will predict events, loss of disinfection, taste, odour, discoloration, bursts or leaks, providing a network that measures, thinks, predicts and takes actions. Timely warnings and analysis of network anomalies then allows operational staff to react before costly failures develop.

 
Street-Level Smart Water Quality Monitoring

ATi’s tried and trusted MetriNet technology has also been developed into an innovative Street Level Smart Water Quality Monitoring solution, offering a new way of delivering ultra-low powered, real-time monitoring for the creation of intelligent, optimised, smart water networks.

Housed within a serviceable, robust, flame retardant and vandal resistant telemetry bollard, this new solution enables distributed water quality monitoring without the concerns associated with below ground-level installations.

 
Zero Water Wastage

MetriNet’s KIWA approved, smart technology also allows samples to be immediately returned back to the network*, resulting in zero wastage. There is no cumulative leakage as the sampled water re-joins the mains flow.

This low-powered system can be installed any application that requires water quality monitoring, including water distribution networks, working alongside acoustic and transient systems. Our monitors are also a vital tool in helping detect and prioritise leaks in a network, enabling flexible, pro-active and strategic network management.

*Requires 0.5 bar difference between inlet and outlet.

M-Node digital water quality sensors

At the heart of the MetriNet solutions are ATi’s industry-leading M-Nodes, complete smart, digital sensors and transmitters housed in miniaturised bodies with the ability to measure 16 water quality parameters.

M-Nodes are equivalent to traditional online instruments and are connected to the water supply using a purpose designed ‘click-connect’ flow cell arrangement. M-Nodes are connected in series to minimise water usage and can run at pressures up to 6 bar. 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 is key with M-Nodes, they can be connected to any data gathering system. The modular nature enables users to assemble a bespoke monitoring package that fits individual site requirements. All M-Nodes plug directly into the MetriNet system and are powered directly from the communications bus.

MetriNet Q51 Portable Controller

The Q51 is a battery-powered device that supports our digital M-Node water quality sensor applications. It can be used with our MetriNet smart water quality system to calibrate or configure individual sensors, or as a complete stand-alone data logger to run M-Node sensors directly. The controller communicates with the Modbus RTU protocol.

Each M-Node is a complete Modbus smart transmitter with a submersible multi-pin connector on the back. If only one sensor is being used, the sensor is connected directly to the controller. If more than one sensor is used, the controller plugs directly into the multi-sensor bus bar, allowing for easy access to all M-Node sensors.

MetriNet User Interface (MUI)
 

For a complete solution, M-Nodes can also be connected to the MetriNet User Interface (MUI). The MUI connects to up to 8 M-Nodes and connects to the outside world in via any ‘ftp’ based system – operating as independent modules that can be linked via a communication bus. The MUI also has on board data-logging with vast data storage capabilities. All M-Nodes plug directly into MetriNet systems and are powered directly from the communications bus. M-Nodes may be added or removed as needed and removal of an M-Node will not affect system measurements. Sensor and bus connectors are IP-67 rated for maximum signal protection.
