RiverRay, a new ADCP for moving discharge measurement. It is Patented Phased array design to provide a small, flat, single-face design with several key advantages.It has velocity Profiling Range from 30 cm to 40 meter. It’s easy to carry, deploy and operate. It has auto adaptive set up (no user setup is required) / data collection which optimize your discharge measurement from bank to bank, thus ensuring the highest quality data without your intervention. DGPS compatible – integrate an external DGPS for difficult conditions, such as moving beds (see video). This ADCP is compatible with Win River II Software. To explore further, click here.



Stream Pro ADCP 

The Stream Pro ADCP revolutionizes discharge and velocity measurement in stream from 15-200 cm in depth. The 'bottom tracking' capability provides the ability to move continuously across the stream to obtain a discharge measurement in two or three minutes instead of thirty minutes to an hour using the older point-by-point method. A wireless data link between the instrument and the user allows flexibility in deployment. You can move the Stream Pro across the channel from a bridge, from a tag line (see video), or by wading rod.

Workhorse series

It is a product line of current-meter profilers which are easy to use and provide premium performance at economical cost. It is available in 3 frequencies varying from 15 m to 600 m reach, users gain unmatched low noise measurements of water currents. Workhorse ADCP’s are compact, light-weight, low in cost, easy to deploy and maintain. High reliability, flexible operation (range and resolution) with real-time checking of data quality, low power consumption and low service requirements meet the broadest range of consumer needs. Upgrades are available for pressure sensor, bottom tracking and operation at depths up to 6000m (see video). Approximately 10000 Teledyne Workhorse ADCP’s have been purchased in 50 countries worldwide.

Ocean Surveyor ADCP 

It adds a new chapter to TRDI's unique contribution to the worldwide open-ocean research fleet. More than 250 vessel-mounted ADCP’s have been installed around the world. These ADCP's provide detailed maps of the distribution of water currents and suspended materials through the water column and along the ship's path. In real time, the ADCP is also used to aid in-situ decision making, to adapt field operations and to understand current regime characteristics. To explore further, click here.

Ocean Observer ADCP

TRDI dominates the offshore oil and gas sector with field-proven instruments designed to facilitate exploration drilling, field development and production. TRDI acoustic Doppler systems and software have been chosen by the majority of offshore operators worldwide to support their exploration drilling programs. This support is provided for station-holding, riser deployment and monitoring ROV operations and marine operations - and the data is all gathered and displayed in real time to enable crucial operational decisions to be made. The user selects between TRDI's high resolution or long range settings for the greatest flexibility in operation. To explore more, click here.

Doppler Volume Sampler (DVS)

Newly released Doppler Volume Sampler™ (DVS) is now available for 6000M operation. DVS is ideally suited for your long-term shallow -- and now deep-water -- moored current measurement applications. The DVS can provide substantially improved data quality over traditional single point solutions, allowing for up to 5 bins of high resolution velocity data over a range of up to 5 meter. It measures velocity profiles at up to 40 times per second, allowing mm/s precision at a 1 Hz update rate. The DVS can be programmed to run a preconfigured sampling strategy, which need not be interrupted should the operator decide to communicate with the DVS to download data or command additional samples. Optional next-generation internal inductive modem and high-precision (0.005°C) thermistor, both from Sea-Bird Electronics, Inc. To explore more, click here.

ChannelMaster H-ADCP

 The compact, versatile and affordable Channel Master is a two-beam, horizontally oriented ADCP designed to obtain high accuracy velocity data at ranges from 1 to 300 meters, utilizing 1 to 128 cells of data. The Channel Master is ideally suited for use in rivers, streams, estuaries, open channels, ports and harbors (see video). To explore more, click here.


The RiverPro offers users a 5-beam solution along with auto-adaptive sampling and a user-friendly interface. The RiverPro has been designed specially to fit into the RiverRay float. This makes it possible to swap the two instruments based on the environment without the need to acquire another float.  To explore more, click here.
