Description
The vibrating wire pore pressure gauge is designed to measure liquid pressure and pore water pressure in pressure vessels, pipelines, soft ground or embankment foundations, dams, and boreholes. It includes a high-precision resistance temperature sensor and lightning protection to compensate for zero-point changes caused by temperature variations. Using high-density epoxy resin and stainless special steel, it enables semi-permanent monitoring.

▣ Applications
① Pore water pressure measurement in soft ground sites
② Water level monitoring in rivers, reservoirs, and standpipes
③ Slope and ground stability studies
④ Monitoring groundwater flow and leakage in dams, embankments, and lakes
