A portable device designed to measure profiles of heave and settlement beneath structures.
A sensitive vibrating wire pressure sensor is located in a cylindrical metal housing which is pulled through a buried pipe. The sensor is connected, via a liquid-filled tube, to a reservoir located located on stable ground. The sensor measures the hydraulic head between the reservoir and its location.
- Independent measurements of settlement can be made at closely spaced intervals providing a detailed profile of differential settlements over a wide area
- The sensor is vented so that barometric pressure fluctuations have no effect on readings
