System Description

The SEBA flood control system is a sophisticated, compact remote transmission system for an economic control of groundwater monitoring stations. Following characteristics distinguish the SEBA top piece:

The compact and robust construction enables easy mounting of the level observer in open areas on a 4”casing with winding. Depending on the location, the sensor (e.g. pressure sensor) can be installed in an existing 4” well together with the SEBA Top Piece (e.g. on a sheet pile, bridge groundwork) or as as separate solution by means of an additional protection tube (1”) which is installed in the water. This keeps the costs for setting up an alarm station rather low!
A sophisticated energy management (time-slot procedure) allows a long battery life time which leads to low maintenance costs. With an optional additional solar cap any battery changes can be avoided.

The SEBA Top Piece can individually be equipped with various sensors according to the user’s needs:

Function principle:

Whenever a threshold value of up to 4 freely programmable parameters (e.g. water level, battery capacity etc) is transgressed, an SMS alarm is sent to upt to 8 different mobile phone numbers.

Additionally to the alarm function, the measured data can be transmitted to a PC via GSM/GPRS. The data are moreover stored inside the integrated data logger. The measuring intervals can be configured freely.

With a notebook or your SEBA HDA and an interface cable, the recorded values can comfortably be downloaded via the RS 485 interface or wireless via Bluetooth (option).

Operation with SEBA-HDA or Notebook

Adjustment and programming of the intelligent SEBA Top Piece can be done with a notebook, an interface cable and our userfriendly configuration software. Alternatively to the notebook, we recommend our rugged and handy SEBA HDA (Hydrological Digital Assistent):

SEBA-HDA "tough and robust companion"

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 up to 30 hours on one charge.

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

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

Automatic Data Retrieval via SEBA-Hydrocenter
 
If you would like to retrieve your data more comfortably and remotely, you can visualise the measuring data in form of graphs and data sheets on our internet platform SEBA-Hydrocenter - either routinely (e.g. once a day) or in case of an alarm (transgression of preset threshold values). Those data can then be downloaded for further use. In order to assure a high battery-durability, the data are only called at preset times.

In case of an emergency (e.g. flooding), the data can be downloaded at much shorter intervals (e.g. once per hour) and transmitted instantly to the SEBA-Hydrocenter (timeslot procedure)
