VW HYDROSTATIC PROFILER
The Vibrating Wire Hydrostatic Profiler is used for the measurement of subsurface settlement. The sensor measures the hydrostatic head of liquid between the sensor and the reservoir locations.
Working principle: A vibrating wire sensor is located within a probe that can be pulled through a buried pipe or borehole. The sensor is connected via a liquid-filled tube mounted on a reel which is mounted horizontally at the reservoir location on stable ground. The reel is free to turn as the probe is pulled through the pipe or borehole.

HPS-3500 (Hanging) and IPS-3000 (Inverted) Pendulums are used to measure the tilt or rotation by measuring the relative internal horizontal displacement of points along a true vertical line. Each has a tensioned, stainless steel wire and the effects of the earth gravitational forces to guarantee a perfectly vertical line between a fixed point and a tensioning mechanism. Typical applications include concrete dams, bridges and high rise buildings.
