The RST Submersible Tiltmeter provides precision real-time remote monitoring of tilt of submerged structures. It consists of a MEMS inclinometer sensor and electronics mounted inside a rugged waterproof enclosure. The instrument housing is machined from solid stainless steel, providing extreme endurance for long-term high-pressure underwater service. The cable entry is a submarine grade connector, which provides watertight performance at depths exceeding 200 meters.

Submersible Tilt Meters are commonly used for:

  • Remote, real-time monitoring of inclination of concrete-face rockfill dam slabs and concrete dams.
  • Monitoring of tilt of retaining walls, piles, and bridge piers.
  • Monitoring of offshore structures.
  • Installation of submerged pipelines.

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!
