Logging data today is not just processing data such as oxygen, pH or levels. We measure and log data from reservoirs, lakes, rivers, streams, creeks, groundwater, surface water, harbors and many other places to help adapt and improve our infra structure.

Logging data far away from urban areas is handled by a battery powered data logger, that gather information and send the information to a SCADA system, dedicated databases or even as e-mails when its suitable to do so.

Publicly placed data loggers are vandal protected, and will send a warning when intruders act.

Sending data once a day will provide at battery life time of up to 5 years.

Information on ground water levels and early warning sewer systems in correlation with buildings nearby urban construction can save millions of Euros in damage.

Chatter is an advanced data logging device, developed by MJK to be working stable and secured in the nature, just as well as in wells, storm flow systems and public places.

Chatter records the levels via MJK Digital Expert Hydrostatic Level Transmitters, stores the data and transfers data via GSM/GPRS as e-mail, SMS or directly to SCADA using the standard ModBus RTU protocol.

Chatter is mainly used to register ground water levels, and storm flow incidents. Furthermore, today the Chatter can also calculate rain intensity and compare this to defined time frames and the data can be used to start pumps, thereby avoiding sewage overflow.
Warnings are send from the device in case of low battery or unauthorized access. This makes it easier to plan maintains routines, as the Chatter does not need manned monitoring.

Chatter is used to monitor and log ground water levels, pressure, temperature, flow etc. in drinking water distribution network systems and boreholes, placed on long distances from main power supply.  Data transmissions can be via a simple SMS or as e-mail with attached CSV package on over cell phone network GSM/GPRS to SCADA systems.

Chatter is perfect for logging the level and state of spare basins. The Chatter works independently of power resources as it is battery powered. The logged data can be transferred via GSM/GPRS on schedule or triggered by alarms. The incoming data can with great advantages be used for to overview the level of for instance sludge tanks, spare basins and clearing tanks.
