The Multilog 2 MetriNet system is designed for monitoring clean water quality, especially for sites without power supply.
It combines ATI's M-Nodes range of digital sensor-transmitters and HWM's Multilog 2 communicating data logger-controller to provide a highly flexible, stand-alone measurement system with telemetry capabilities for remote alerting and monitoring.
This combination also allows the coupling of physico-chemical monitoring of other measurements such as pressure or flow on the selected network portions with instrumentation.
Continuous monitoring of water quality in drinking water distribution networks or other installations supplied with clean water (greenhouses, fogging systems, etc.).
The wide range of M-Nodes digital sensor-analyzers allows the selection of useful measurements for each application (Chlorine, Turbidity, pH, Dissolved Oxygen, etc.); each system can have up to 8 monitored parameters, from there it is possible to add other sensors connected to the Multilog 2 recorder (pressure, flow, level, etc.)
The Multilog 2 Metrinet is particularly suitable for installations without power supply, thanks to its ability to operate using batteries.
However, it can also be used for powered sites and offers the advantage of continuous monitoring in case of power failure.
A version of the Multilog 2 MetriNet can be installed on pressure control valves and then couples to quality measurement, monitoring of upstream/downstream pressures; the water withdrawn for analysis is then reinjected into the network.

MOUNTING AND OPERATING PRINCIPLE
The Multilog 2 MetriNet allows the assembly of 1 to 8 measuring chambers. Each chamber contains an M-Node sensor with a simple bayonet connection. A rotary locking ring allows the chambers to be clamped together for easy assembly.
DIN rail mounting clips attached to each chamber allow easy mounting and assembly on a rail.
A flow control device is built into the cell outlet fitting to control sample flowrate at 0.2 l/min, with a maximum inlet pressure of 6 Bar (87 psi).
The system can be operated in continuous or cyclic mode controlled by the Multilog 2:
An internal screen protects the flow element from particles larger than 100 µm that could enter the system and can be easily removed for inspection and cleaning if necessary.
