The Digital Hydrostatic Profile Gauge is used to monitor the profile of settlement or heave and is predominately used for monitoring beneath embankments or structures where access to the surface is not possible.

The Digital Hydrostatic Profile Gauge is positioned on the concrete block or reference datum pin.

The probe is pulled along the borehole and is positioned using physical markers on the connecting tubing. The Field PC software guides the user to position the probe at each one metre marker interval; these are marked and numbered on the tubing. At each interval, the user initiates a reading which records the pressure differential at that point between the reel and the probe. This reading is transmitted from the cable reel to the Field PC via a wireless link.

The probe is datumed at an external topographic reference point for each profile. As the distance position of the probe is known from the markers, subsequent profiles can determine the delta pressure at each given point. From this information, the change in elevation of each point along the profile can be measured.
