The "US-500" is an airborne ultrasonic wave height gauge capable of accurately measuring sea level fluctuations with long-term stability. It can measure not only waves but also various long-period waves that are difficult to measure with tide gauges. Additionally, because it does not require underwater work, installation and maintenance are easy. It is suitable for purposes such as tsunami observation, storm surge observation for coastal disaster prevention, and shoreline management through long-period wave observation. 【Main Specifications】 ■ Measurement Range: 1m to 11m ■ Measurement Items: Surface Waves, Temperature, Average Water Level ■ Output Ports: Analog, Digital (RS-232c) ■ Power Supply: AC100V or DC12V ■ Power Consumption: Approximately 20VA ■ Weight: Approximately 11kg *For more details, please download the PDF or feel free to contact us.

The "WALRUS SERIES" is a marine observation device that monitors wave conditions, currents, and water level fluctuations in coastal areas up to a depth of 50 meters in real-time using sensors installed on the seabed. It has transitioned underwater cable communication from traditional analog signals to digital signals, achieving robust transmission resistant to external noise without the need for repeaters over long distances. Additionally, it features improved operability and visibility through a touch panel, and its design anticipates future functional expansions, allowing for upcoming model developments and functionality upgrades. 【Features】 ■ Fully compatible with existing products ■ Improved quality of underwater cable transmission ■ High-quality measurements ■ Enhanced user interface and future expandability *For more details, please download the PDF or feel free to contact us.

The "DFT-3" is a digital float-type tide gauge that transmits the up-and-down movement of a float floating on the water surface to a pulley via a wire, allowing for the observation of tide levels based on the rotation angle of the pulley. Observation data is output to both a compact flash card and digital output. Since it is recorded in ASCII format, transferring and analyzing the observation data is easy. Additionally, the observation data can be externally output via RS-232C, making it compatible with various transmission systems. 【Features】 ■ No wire slippage, enabling accurate tide level observation ■ Backup available with built-in battery during power outages ■ Observation data is output to both a compact flash card and digital output ■ Recorded in ASCII format, making data transfer and analysis easy ■ Observation data can be externally output via RS-232C, compatible with various transmission systems *For more details, please download the PDF or feel free to contact us.

The "LGSM-2.V2" is a high-precision level gauge used for underwater leveling surveys of underwater structures, underwater topography, and other underwater construction works in ports, coastal areas, lakes, and rivers. The leveling method is a simple approach that applies the principle of communicating vessels, allowing for high precision and stable measurement values. Compared to general staff measurement methods, it reduces the labor of the operator and the surveying time (by 1/2 to 1/4), and due to underwater work by divers, there are fewer constraints from weather conditions, making project management easier. 【Features】 ■ The measurement principle applies the same principle of communicating vessels as "water leveling," enabling high-precision and stable measurements. ■ Compared to general staff measurement methods, it reduces the labor of the operator and the surveying time (by 1/2 to 1/4). ■ Due to underwater work by divers, there are fewer constraints from weather conditions, making project management easier. ■ The measurement range is within a 50m radius centered on the reference point, with a height difference range of +5 to -15m. ■ The accuracy is ±2m within ±2cm, and other ranges can be measured within ±1%. *For more details, please download the PDF or feel free to contact us.
