BIOAqua Ground Water Quality Monitoring System


BIOAqua Ground Water Quality Monitoring System is a groundwater control system that is capable of integrating different types of probes, giving great flexibility to make the necessary measurements for each application.

It is marked by its communication system GSM / GPRS, which minimizes costs and improves communication






BIOAqua Ground Water Quality Monitoring System – Operation
System Operation:

Smooth Operation of the system ensures

Monitoring, recording and reporting the level and quality of water in aquifers, allowing assessment on available resources, effects of exploitation and detection of pollution episodes.

  • The integration of almost all types of probes available on the market gives it the flexibility necessary to meet the needs of each facility. Results are presented in a single front-end communication (OPC Driver UCR) to facilitate the integration of the probes to the operating system.

  • Definition of the reading frequency of the various probes independently connected to the computer.

  • Transmission of information in real or deferred time, as needed and depending on the feed-in system.

  • Reduction of installation costs through power management and communication system.
