Lightweight structure, stable navigation performance and foldable design for convenient transportation and deployment.
Optional built-in dedicated digital transmission radio module, achieving a maximum communication range of 3 km.
4G IoT wireless radio is available as alternative, enabling data transmission within 4G signal coverage areas.
Reserved mounting bases for GPS receivers and heading sensors for integrated positioning solution.
Optional ADCP Models
Two series ADCP for selection: Five-beam RIV F5 ADCP with independent depth sounding function, and horizontal RIV H series ADCP for shore-mounted horizontal current profiling.
RIV Series 4-Beam ADCP
Equipped with advanced self-developed IOA broadband technology, Frankstar RIV Series 4-Beam ADCP (available in 1200 kHz, 600 kHz and 300 kHz versions) delivers highly precise and reliable flow velocity measurement data, performing steadily even under severe river hydrological conditions. This ADCP supports seamless integration with mainstream peripheral devices including gyroscopes, GPS modules and radio data transmission stations. Custom configurations for survey vessels and triple-hulled boats for mobile flow monitoring are also available upon request. Deploying Frankstar RIV ADCP effectively cuts down tedious manual field work, allowing researchers and engineers to focus more on data analysis and research.
