Description SenSpot™ wireless scour meter provides an easy way to install a scalable solution for measuring bridge scour, hydraulic damage, or slope stability. Bridge scour refers to the removal of sediment such as sand, soil, and rocks from around bridge piers or abutments by fast moving flood current. It can cause erosion around the bridge piers or abutments. As scour occurs progressively, supporting material around the bridge foundation is removed and it can lead to settling or other forms of foundation instability. Resensys Scour Probe SenSpot™ measures soil/sediment level close to the...

Typically, the temperature variations are smaller at nodes in the water comparing the nodes inside the soil. Installation Wireless transceiver box comes with mounting flanges. It can be installed either with screws and anchors through the flange holes or with VHB adhesive tape (for steel and smooth surfaces). Email: info@resensys.com
