For automation of level measurement in dams, piezometers are installed in existing holes. These sensors are interconnected to communication radios, or other communication architectures, where the measured values will be transmitted to a central and consequently made available for implementation in the customer's network. LLK also provides the solution with options for solar panels, batteries or other types of energy generation for system autonomy in the field.


Product Features and Specifications

Communication Architecture (TA)

The communication structure is dimensioned and designed according to each project, below is an example of architecture used for automation and communication of piezometers in dams.


From there, with the selection of the gateway in a suitable protocol for the plant, the system can be interconnected with the local network, computers, PLCs and data acquisition systems.
