System Description

The GSM/GPRS transmission system SlimCom is a miniature data transmission system for an economic control of groundwater monitoring stations. The following features are characterisitc for the SlimCom Sytem:

1. Compact Construction

Our SlimCom module with integrated GSM/GPRS modem and antenna is suitable for installation in observation wells starting from 1 /0.5 ” diameter.
For observation wells 2” or bigger, control measurements with electric contact meters (KLL) are possible without removing the system from the casing.

2. Energy Management

Standardly, the system comes with three 1,5V Alkali manganese batteries. A sophisticated energy management (time slot procedure) provides high battery lifetime and therefore a minimum amount of maintenance. A battery change is blindingly easy...!
For shorter download intervals, the SlimCom system can be equipped with two 3,6 V lithium batteries. With a weekly download interval the lifetime of the sytems is more than 10 years.

3. Automatic call of the measuring sites and SMS alarm

The System can be called comfortably in individually programmable time slots via the software DEMASole. Independently, alarm limits can be defined (e.g. water level, battery capacity). SMS alarms can be sent to up to 8 different mobile phone numbers, as well as by email and to a facsimile instrument.

Operation with SEBA-HDA or Notebook

The adjustment and programming of the SlimCom System can be done with a notebook, an interface cable and our userfriendly configuration software WBedien/SEBA Config. Alternatively to the notebook, we recommend our trailworthy, handy SEBA HDA (Hydrological Digital Assistent).

SEBA-HDA a tough and robust hand-held

Robust PDA for tough field operations and an alternative to the notebook. Vibration, impact, dust and water resistant magnesium housing according to IP 67 for the operation between -30°C and +60°C. Operation time of up to 30 hours on one charge.

Simple operation resp. input of parameters (e.g of control values) via TFT colour LC-touchscreen or stylus

Groundwater Monitoring System-Online Type SlimCom

Included in the delivery:
-Operation software SEBA-WBedienCE for simple ,
  programming, adjustment and operation of the
  entire SlimCom and Dipper-3 System as well as for
  transmission of the stored values to your PC.
-Evaluation software MGMDS/MLMDS CE for
  plausibility check of stored measuring data in form
  of graphs and data sheets.

Automatic monitoring data retrieval with DEMASole or with Hydrocenter via Internet

Storage of data (SQL-database) with DEMASdb
and Visualisation of measuring values (graphs/lists) with DEMASvis

In order to conduct an automatic monitoring data retrieval from the SlimCom , the comfortable DEMASOle software is implemented and the data can automatically be stored in DEMASdb. Alternatively the standardized call protocol DDP (descriptive data procotol) also allows the retrieval of recorded data with nonproprietary software, i.e. WISKI/SODA (Kisters), MAWIN etc.
DEMASdb offers a comfortable graphical user interface, an automatic data retrieval software (DEMASole) as well as an evaluation module (MGMDS/MLMDS) which includes various calculation functions. Depending on the size of the network, DEMASdb is provided with a paradox-, MySQL-, Oracle- or MS SQL-database. Optional DEMABdb can also be integrated with an already existing SQL database (e.g Oracle, SQL-Server). DEMASdb enables a simple data management of monitoring networks of various extents: small (10 sensors), middle (50 sensors) and large (> 100 sensors).
