Central California, USA

Valarm remote monitoring systems have recently been deployed near levees and the Feather River in central California, north of Sacramento, for early warning and community safety.

The systems comprise GEOKON 4500S Vibrating Wire Piezometers, GEOKON LC-2 and LC-2×4 Dataloggers interfaced with Yoctopuce sensors hubs using Ting GSM cell networks, powered by deep cycle, sealed lead acid (SLA) marine batteries. Measurements are uploaded at user defined intervals to Tools.Valarm.net for analysis and visualization in data tables, on maps, 3D earth globes, graphs, historizers, and web dashboards.

These remote monitoring deployments are part of a California government project which utilizes the expertise of agencies and organizations like Wood Rodgers, Inc. environmental engineering consultants, Jensen Drilling Company, HDR, Teichert Construction Company, and the California Department of Water Resources (DWR) to integrate GEOKON vibrating wire sensors with Valarm Tools Industrial IoT software.

Hinton, West Virginia, USA

Bluestone Dam, in Hinton, West Virginia, was built between 1941 and 1949 to control flooding in the New and Kanawha River Valleys. It’s constructed of a series of 55 x 165 ft high, 22 ft wide (at base) interlocked concrete monoliths. Recent calculations identified the possibility for dam failure due to the monoliths sliding on the bedrock.

As a result, a total of 216 high-strength anchors, comprising of 58 to 61/0.6 high strength multi strands, were installed at critical monoliths to stabilize the dam. This photo, kindly shared by DSI America, shows a GEOKON Model 4900-3500-12 Vibrating Wire Load Cell mounted on the 15,000 kN hydraulic ram (20" stroke) used to stress the anchors.
