Complete Metocean Solutions
There are many options available from RBR for measuring water level, be it pure water level, tide or tide and wave. Depending on your required specifications, the depth and the accuracy you require, the team at MSI can tailor a solution to meet your project requirements.
The RBRsolo³D and the RBRduet³TD are the most compact, lightweight and versatile depth, and temperature & depth loggers for tide and wave measurements. Models available are:-
RBRvirtuoso³D and the RBRduo³TD are the most flexible, option packed single and dual channel loggers for depth and temperature & depth loggers including tide and wave measurements. Models available are:-
The RBRquartz³ Q tide and wave recorder uses an integrated Paroscientific Digiquartz® pressure sensor for the best-in-class initial accuracy (10ppb) and low drift performance. The RBRquartz³ Q is intended for long-term autonomous or real-time observations of water level, tides and waves. The stable pressure sensor is able to resolve small changes in water level over long deployments. Flexible measurement schedules and burst sampling permit applications for tide, wave, and sea level measurements. The RBRquartz³ Q has a large memory capacity, sufficient power for extended deployments, and USB-C or Wi-Fi download for large data files.

The RBRquartz³ BPR (bottom pressure recorder) uses an integrated Paroscientific Digiquartz® pressure sensor for the best-in-class initial accuracy, resolution and low drift performance. The RBRquartz³ BPR is intended for long-term autonomous or real-time observations of water level, tides, and tsunamis in deep water. The high resolution (10ppb) and accuracy (0.01% FS) quartz pressure sensor is able to detect minuscule changes in water level from the bottom of the ocean. Continuous measurements allow the RBRquartz³ BPR to be used for tsunami detection and early-warning systems when connected to a cabled real-time network. Flexible measurement schedules and configurable integration times permit applications for tide and sea level measurements when powered on internal batteries.
