Penstock Pipeline and Saddle Block Monitoring

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.
