Geodaq provided consulting services for design and implementation of a remote monitoring program to characterize groundwater levels and relative movements between penstock pipeline segments and saddle blocks.
A system of Geodaq GST modules were mounted at each saddle block to accurately digitize displacement and temperature readings.
All readings are transmitted over a single cable to the Geodaq GCM4 controller using a Controller Area Network system, greatly increasing the resolution, accuracy and stability of the displacement values over time and temperature.
A wireless Ethernet system at two stations was used with high gain antennas to transmit results over great distances to the power house and on to the Geodaq web server.
Results are made available via our password protected web portal for complete viewing of plots and data tables.
Alarms are set for instant notification in the event certain displacement levels are obtained.
The Geodaq monitoring system has been operating since installation in 2013, and displacement results show stability below 0.001 inches over time and temperature.
