Data Acquisition & Telemetry


Continuous water monitoring at a large gold mine

July 2013 Data Acquisition & Telemetry

Water quality as part of environmental responsibility is a key element to triple bottom line reporting, with water licensee operators needing to provide data for licensing authorities and compliance data for reporting. Omniflex has tackled the challenges for this type of remote monitoring application head-on and in the process overcome a number of key challenges.

* Remote unprotected and unmanned sites.

* Solar powered equipment.

* Vandal proofing.

* Automated operation.

The project required that monitoring systems be installed at key sites, geographically spread over a few hundred square kilometres, to track wastewater outflows to ensure that the mine has a complete view of its discharge and treatment processes over its entire operation. Data collected is shared internally across the enterprise, with processing plants, to a GIS system for open reporting and with the Department of Water Affairs.

Measurements at remote sites

Any analytical measurements required can be incorporated into the system. Typically the following are required:

* Flow rate.

* Totalised flow.

* Dissolved oxygen.

* pH.

* Conductivity.

* Turbidity.

System architecture

All three of the system architectures were required for the client to manage data across the organisation and satisfy their management objectives. Omniflex provides a cost effective adaptable and extensible solution, from single point small system to large corporate enterprise monitoring, allowing the integration of existing equipment and legacy systems and providing the management tools to manage an aggregated view of the enterprise. The labour intensive data capture and collation process has been eliminated and the system enables automated reporting for compliance management and environmental action plan reporting.
