OSSI-010-003 Wave Gauge
High-Resolution Wave and Water Level Measurement System
Product Description
The Ocean Sensor Systems OSSI-010-003 Wave Gauge is a self-powered, high-resolution instrument designed for precise measurement of liquid surface height at up to 30 Hz. Ideal for applications such as monitoring waves, tides, wakes, and water levels in oceans, lakes, tanks, and other fluid environments. The unit stores more than a year of data on standard CompactFlash cards and is built for durability in long-term deployments.
