The Enviko SK-DVM vibrating wire void meter provides long-term measurement of voids caused by deformation between the concrete face slab and the cushion layer of concrete face rockfill dams, and between other concrete structures and their foundations. It is built from an SK-DM0 vibrating wire displacement meter fitted with dedicated accessories. A built-in temperature sensor records the temperature at the installation point, and a smart ID chip can be fitted on request.
