MWM - Model m-log -Multi-Channel Data Logger
Existing measurements (e.g. flow meters), which cannot transfer data, can be equipped with the MARTINEK m-log™ data logger at any time. The data is automatically sent to AQUALYS and evaluated. The data pulse logger can be extended with an external and internal pressure transducer (also available separately).

The evaluation software is an essential part of the WLM-SYSTEM. The software is compatible with Windows 7 / Windows Server 2012 and higher and is operated with a SQL Server database. A hosting service can also be offered on request.
The software enables comparative measurements with simultaneous values from the previous day, triggers an alarm when one of the above-mentioned variables/parameters changes and identifies the leak zone. The analysis data is displayed visually in the network map (GIS plan).
By changing the colour of the individual symbols in the network diagram from green to red, an exceeding of the limit set by the software is indicated. This status display can be set for single sensors as well as for sensor groups monitoring a virtual or physical zone.
This allows the user to see at a glance whether significant changes have occurred in the network. In addition to this automatic data analysis, the WLM-SYSTEM enables an immediate pipe burst warning.
The software also allows a variety of comparison and query options, as well as automated data export and import. This is particularly important when the monitoring system is integrated into an existing infrastructure.
Data from different flow, pressure or level meters can be imported into AQUALYS and calculated. Thus, the existing measurement technology can be integrated almost completely into one system only.
