HIDROVIA S.A.

This company, concessionaire of the dredging and maintenance works in the Access Channels to the Port of Buenos Aires, entrusted TECMES with the design, construction, installation, and getting into operation of a tide recording network system with more than 90 measuring points.

This network consists of remote stations installed at beacons within the Río de La Plata, Paraná delta and Paraná River, a data collecting Central station and 3 secondary stations.

The communication system between the central station and the remote ones occurs by means of cellular telephony.

The remote stations Model TS 2621 - C, installed on top of beacons driven into the river bed as well as in floating buoy systems (Spar buoys) located in the bed of the Río de La Plata itself, used TS 310-P sensors of the submersible type for level pressure measuring.

This remote station has the peculiarity of storing the data in an internal memory, always transmitting the values acquired since the last interrogation.

The power supply is obtained by means of battery and solar panels.

The central station also possesses a base for storing the data obtained by sensors of level and of different parameters, such as water quality and buoyage systems operation, and transmits the information to 3 secondary central stations through telephone, thus rendering the information available for several users.
