ADP/ADCP
Intro: The ADP/ADCP is an accurate, reliable and inexpensive current and wave profiler manufactured by SonTek.

The ADP/ADCP is an accurate, reliable and inexpensive current and wave profiler manufactured by SonTek. It is available in a variety of ranges and configurations and is suitable for real-time current monitoring, detailed river surveys and long-term autonomous deployments. It has a profile range of 3m up to 180m and is suitable for deployments in excess of one year.

The simple to use ADP/ADCP uses SonTek’s proven Doppler technology to take the most accurate and robust current measurements possible. It measures 3D velocity in a user-specified number of depth cells and with no moving parts it is highly resistant to biofouling even in the most challenging environments. The ADP/ADCP also does not require recalibration or factory maintenance.

By using state-of-the-art transducers and electronics, designed to reduce side lobe interference problems that plague other current profilers, the ADP/ADCP can access the near-boundary (surface or bottom) current measurement which is critical to many shallow water applications.

Seabed Mounting Frames
Intro: OSIL’s Seabed Frames are designed to allow a whole range of instrumentation to be attached to their stainless steel frame which can then be lowered into the sea and rest on the seabed.

OSIL’s Seabed Frames are designed to allow a whole range of instrumentation to be attached to their stainless steel frame which can then be lowered into the sea and rest on the seabed.

Each frame is adapted to the client’s needs and a wide range of dimensions can be catered for. The frames come complete with PVC clamps which are made to suit the instrumentation that is to be mounted on the frame.

The open-framed 316 stainless steel frames are available in various heights:

The smallest frame available has a height of 300mm and it has been designed as an anti-trawl mount frame, ideal for mounting ADCPs on. The frame means that the ADCP can be placed on the seabed on a stable platform and be resistant to fishing trawls whilst maintaining reliable data.
The larger frames are suited to studies on parameters such as turbidity as multiple turbidity sensors can be accurately fitted to the frame at varying heights.

There are two generic Seabed Frame designs:

A Square pyramid frustum with a base dimension of 1 metre.
An Octagonal pyramid frustum with a base dimension of 1.5 metreswhich can be split into two sections for easy transportation. This design can offer greater stability than the square version due to its octagonal base.

However, the design and dimensions of the frame is down to the client as each Seabed Frame is designed specifically for each customer.

Intro: The Argonaut-SL is a 2D side-looking current meter suitable for ports, harbours, platforms, riverbanks and bridge mounting.

The Argonaut-SL is a 2D side-looking current meter suitable for ports, harbours, platforms, riverbanks and bridge mounting. Three new version of the Argonaut-SL have been introduced by SonTek, the SL3000, SL1500 and SL500. They have been designed to be smaller, sleeker and more powerful than the previous versions. The sampling ranges of the three SL’s vary from 0.1 to 5m for the SL3000, 0.2 to 20m for the 1500 and 1.5 to 120m for the 500.

RiverCAT System
Intro: The RiverCAT is SonTek's turnkey integrates river discharge measurement system.

The RiverCAT is SonTek's turnkey integrated river discharge measurement system. It comes complete with catamaran, GPS interface, and radio modem interface and uses a Mini-ADP along with SonTek’s RiverSurveyor package. The package includes a 10cm diameter transducer head, an integral compass/tilt sensor, external DGPS interface, and replaceable alkaline battery power. The reduced diameter head creates very little flow disturbance, making it ideal for measurements in shallow rivers.

The RiverCAT integrates the RiverSurveyor with a set of rugged 69cm aluminum pontoons into one package that is ideal for towed or tethered applications at flow speeds less than 1.5 m/s. This "Pack and Go" acoustic Doppler current profiler/discharge measurement system weighs less than 12 kg when assembled, and neatly fits into a portable hard-plastic case with wheels.

The RiverCat comes with two pontoon options:

Rugged and compact aluminum hulls, two plastic pontoons for high flow applications
The trimaran for added stability under adverse conditions.

Easily removable from the pontoons, the RiverCAT electronics can be used on alternative platforms of your choice. A seamless integrated DGPS system (optional) makes the RiverCAT a complete package for bathymetric surveying.

No other river profiler can match the features, flexibility, and performance this system offers. The RiverCAT can be tethered from a line and towed across the river (remote operation) or mounted directly to a boat (vessel-mount operation).

Features:

69cm aluminum catamaran (with case)
Integrated, two-way, spread-spectrum radio modems
Battery compartment with replaceable "C" cells (Mini only)
Hard plastic shipping case with wheels
