MJK has developed Chatter, which is an advanced data-logging unit that runs stably and safely in nature, wells and overflow structures.
Among other things, Chatter logs level via the Expert hydrostatic level transmitter. Data is stored and transferred via GSM/GPRS as e-mail, SMS or in CSV format directly into your SCADA system, e.g. via RS485 ModBus.
Chatter data logger is mostly used to monitor for overflow in wells and sewer overflows.
Alerts are sent from the device in case of low battery or unauthorized access. MJK Chatter does not need regular supervision, which makes it easier for you to plan your time.
For efficient management of drinking water, Chatters are often used to monitor and log level, pressure, temperature and flow rates in e.g. drinking water distribution and boreholes located outside normal power sources.
Thanks to the intelligent communications solution, it is possible to connect the controllers so that they can retrieve data from meters everywhere on the system. Data is securely transmitted as an SMS, e-mail with attached CSV file or over the GSM/GPRS network.
The MJK Chatter is perfect for logging i.a. level in overflow basins. Chatter does not need a power cable, as the built-in battery handles the daily tasks.
Logged data is transmitted via GSM/GPRS, either as planned by you, or triggered by alarms. The latter as security against authorized access to technical installations.
In Denmark alone, there are currently more than 1,200 Chatter units monitoring water levels in nature. Among other things, lakes, streams and groundwater levels are measured for statistical use.
To save power, Chatter is only activated for a very short period at a time. Therefore, the battery can last up to five years when measuring once a day.
In addition to monitoring nature, Chatter is also used in many building-sites. Here, the groundwater level is monitored to avoid subsidence damage to nearby buildings which may lead to compensation claims.
