Description

The ROWE Technologies SeaWATCH DF (Dual Frequency) and SeaPROFILER DF product family of Acoustic Doppler Current Profilers (ADCPs) lead the industry in state of the art acoustic Doppler technology. ROWE’s second generation electronics provide the ability to use two independent acoustic frequencies in the same instrument.

Each of the frequencies can be independently controlled allowing for near simultaneous acquisition of high resolution, short range current profiles from the high frequency channels, and long range, lower resolution profiles for the low frequency channels. With the SeaWATCH DF and SeaPROFILER DF you truly have two ADCPs in one!

With this DF ADCP you do not need to forfeit performance or flexibility. All of the same core signal processing functions available in the single frequency ADCP model are available in the DF model. This includes broadband, narrowband and pulse-to-pulse signal processing as well as the ability to track the bottom and obtain earth-referenced velocity measurements.

Both the SeaPROILER DF and SeaWATCH DF ADCPs are well-suited for a variety of coastal and offshore oceanographic applications – including meteorological and wave data acquisition, environmental management, coastal engineering site assessment, and oil/gas exploration and drilling. The systems are easily deployed on buoys, moorings or sea-floor structures.

The SeaPROFILER DF, SeaWATCH DF and SeaSEVEN ADCPs are available in 300 kHz, 600 kHz, or 1200 kHz – you select which two frequencies you want.
