Precision Liquid Settlement Array Manual
The Precision Liquid Settlement Array provides reliable, wireless, real-time remote monitoring of settlement and heave which may occur at excavation sites, tunneling projects, underground openings and related applications.
The Precision Liquid Settlement Array provides reliable, wireless, real-time remote monitoring of settlement and heave which may occur at excavation sites, tunneling projects, underground openings and related applications. It is ideal for monitoring under fills, preloads, embankments and grouting near structures. Users have real-time access through an internet connection on a PC and can also receive updates through email at chosen intervals, when used with an RST data logger.

I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
