Chatter is an advanced data logging device developed by MJK to work in a stable and secure way - in nature as well as in wells, storm flow systems and public places.
Chatter records levels via MJK Digital Expert Hydrostatic Level Transmitters. It stores 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. This 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.
In drinking water distribution network systems and boreholes placed a long distances from main power supply, Chatter is used to monitor and log ground water levels, pressure, temperature, flow etc.
Data transmissions can be via simple SMS, or as e-mail with attached CSV package over cell phone network GSM/GPRS to SCADA systems.
Chatter is perfect for logging level and state of spare basins. 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 advantageously be used for an overview of the level of, for instance, sludge tanks, spare basins and clearing tanks.
In Denmark alone, more than 1,200 Chatter devices are constantly monitoring water levels in ground water, lake streams and such. In the forest areas, the data is providing the Danish Nature Agency with important data on how the nature changes or if there is immediate danger of flooding of roads or areas.
To save power, the Chatter only supplies power to the connected MJK Expert Hydrostatic Level Transmitters while it actually measures. This often lasts for approximately teen seconds. This will make the battery last up to five years.
Chatter is also used on many construction sites to monitor the lowering of the ground water level. This is in order to give a warning in regards to avoiding damage to the construction site and structures.
