SLR - Sea Level Recorder
The SLR
Sea Level Recorder is a state-of-the-art and very
versatile system for accurately measuring and recording of water level, with
automatic internal compensation for barometric pressure.
The SLR
continuously integrates pressure samples to obtain water level measurements
unaffected by wave action. Water level integration intervals and durations are
programmable. The large memory allows
frequent water level
recording.
The SLR includes OceanPro™ for Tides, a comprehensive Windows
program including deployment planning, instrument setup, data retrieval and
plotting, time series analysis, and statistics reporting.
