Tide and Wave Gauge(Gravity Type)
The Tide and Wave Sensor by Frankstar provides high-accuracy wave and tide measurements using RNSS-based velocity sensing and low-power onboard processing.
Continuous measurements and algorithm-based averaging enable precise tide level determination, while configurable wave acquisition supports the extraction of key wave parameters such as significant wave height, wave period, and wave direction. In addition, integrated positioning and timing functions enhance data reliability and synchronization.
Housed in a compact, marine-grade enclosure with RS232 communication and clamp mounting, the RNSS Wave Sensor is well suited for deployment on observation buoys, unmanned surface vessels, and other floating platforms, supporting long-term oceanographic monitoring, coastal engineering, and scientific research

Tide and Wave Gauge (Pressure Type)
A self-developed, high-precision wave and tide recorder designed for simultaneous monitoring of tides and waves, enabling accurate and reliable multi-parameter oceanographic measurements. The instrument provides comprehensive wave and water level observations, including tidal level, significant wave height and period (H₁/₃), one-tenth wave height and period (H₁/₁₀), maximum wave height, mean wave height, and their corresponding wave periods.
The system features on-board 32 GB solid-state data storage and is powered by two 3.6 V lithium thionyl chloride batteries, ensuring long-term autonomous operation. Configurable sampling rates of 2 Hz or 4 Hz allow flexible deployment to meet different monitoring requirements, with a measurement range of up to 20 m or 50 m (optional).
With a compact, robust design, the recorder can be easily mounted on various structures or platforms, making it well suited for long-term deployments in coastal and offshore marine environments, lakes, harbors, and groundwater monitoring applications.
