River Surveyor 6000 -
Acoustic Doppler Current Profiler


The River Surveyor 6000 ADCP is designed for measuring river discharge and surveying river current structure. While the boat is moving, the ADCP rapidly measures current velocities throughout the river depth along the boat's path. Combining all this information instantaneously, the ADCP measures river discharge while you are crossing the river.


Profiling Features:

Bottom Tracking The River Surveyor includes bottom tracking capability to measure the ADCP speed and direction over ground and to calculate discharge while you cross the river.
Water Profiling Modes System includes general profiling capability as well as high resolution profiling modes for shallow and slow flow conditions.
Standard Software: River Surveyor software for real-time current measurements and discharge calculation, integration of external heading, GPS, and depth-sounding data. River Surveyor consists of modules for deployment planning, data acquisition, and data playback. Utility programs are included for converting binary files to ASCII format and system diagnostic testing.

River Surveyor ADCP  

30 lbs.



ADCP Boat Mount

This is a lightweight fabricated aluminum mount assembly that allows an ADCP to be deployed off the side of any size survey boat. It is made from aluminum pipe that mounts across the gunwhales and suspends the ADCP down into the water. Specify boat width and draft.

ADCP Floating Tethered Mount -
Rivercat System

This is a welded aluminum dual-hull catamaran with separate water-tight compartments filled with closed-cell foam. The floating tethered mount allows the ADCP to be mounted in the center resulting in a low-profile unit with a high gross buoyancy. It is finished with a smooth finished marine-grade epoxy paint. The unit is designed for both dual side swivel cable pivots for operation from both banks or a center cable swivel connection for use with a cableway or bridge. The unit works extremely well with the Tacoma Bank-Operated Cableway system for tethering and moving the ADCP across the river. The small, light, rugged River Surveyor ADCP allows for a flexible range of mounting options.

ADCP Sounding Weight Mount

In extremely high gradient flood condition rivers it is hard to even keep an ADCP in the water. The bottom of the 300 lb. sounding weight can be bored out for an ADCP to be installed in the bottom. The sounding weight can then be suspended with a Type E crane with four-wheel truck or Texas Boom Assembly from a vehicle.

Cableway ROV


This is a cableway remotely operated vehicle (ROV) for ADCP suspension from an existing cableway. This is a smaller, self-powered version of the original Saskwater ROV designed to adapt to existing cableways. It holds its own battery so that no power cables are required to extend out to the unit. The ROV unit is RF controlled for both out and back and up and down with two separate 12 VDC motors.

Aquanaut 6100-Acoustic Doppler Current Meter

The Aquanaut 6100 is a side-looking Doppler Current Meter with variable range. It is easily installed on a riverbank, bridge abutment, or other vertical structure. The Aquanaut is an advanced Doppler sonar for precise water velocity measurement in a horizontal layer. Robust, all-digital signal processing ensures flow measurement within a user-programmable cell extending up to 75 ft (22 m) away. Flow disturbance caused by the mounting structure can be eliminated by beginning the measurement cell several meters away from the instrument. The Aquanaut never requires calibration, and velocity accuracy is not affected by biological growth. Options for water level measurement, water quality, telemetry, and flow calculation extend the capability of the Aquanaut to a wide variety of applications.

UVM Ultrasonic Velocity Meter -
Transducer Mounts

Measuring water flow in a canal, estuary, reservoir or bayou is often a challenging project as 1) the water velocity is often below the measuring range of the flow instruments, and 2) stage often has no direct relation to discharge. Measuring slow or oscillating flow can now be easily done by installing and using an ultrasonic velocity meter (UVM). The UVM sends sound pulses back and forth between a pair of acoustic transducers and measures the time required for the sound to travel in each direction. The transducers are mounted on opposite sides of the river at an angle to the water flow. The sound pulse travelling against the flow takes a longer time to travel from one transducer to the other, as compared to the sound pulse travelling with the flow. If the flow is zero, the sound will take an equal amount of time to travel in each direction. A major part of installing the UVM is to mount the transducers in the water. These mounts must be rigid, and must hold the transducers so that they point directly at each other. There is an allowable aiming error of approximately 3 degrees, which includes both horizontal (azimuth) error and vertical (elevation) error.

The mounts are rigid to hold the transducers within the allow able aiming angel under all reasonable conditions.
The mounts are adjustable so that the transducers can be aimed at each other, even if the supporting structure is not vertical or level. The mounts should be able to adjust for supporting structures that are leaning at an odd oblique angle, including structures that are leading both to one side and forward (towards the acoustic path) or back (away from the acoustic path).
The mounts are attachable to concrete pilings without drilling into the pilings.
The mount assemblies are low-profile to minimize the possibility of debris snagging on the transducers or knocking them out of alignment and the mount assembly is strong enough so that it is not disturbed by river ice formation or breakup.
The mount is moveable in the vertical direction so that the transducer assembly can be raised above the water surface for inspection, aiming adjustment or repair, then returned to the operating position with the correct aiming settings.

Flow Tracker 6300 ADV - Acoustic Doppler Velocity Meter

The Flow Tracker ADV has been adopted to be used with a top setting wading rod to make wading discharge measurements. The ADV uses sound transmitted in the water to measure point water velocities. It is designed to mount on a standard top setting wading rod with a special offset support to set the velocity measurement at the same place as a current meter. Flow Tracker 6300 ADV electronics with keypad and LCD display can also be installed with a rod mount to attach directly to a top setting rod. The ADV readout uses USGS algorithms and the .2, .6 and .8 standard depth measurement system and does calculated discharge at the end of a measurement. The ADV can be used in streams as shallow as 1 inch and has a velocity range of .003 to 16 fps. (.001 to 5 m/s). Includes 10 MHz 2-D ADV probe (10 cm distance to sampling volume) mounted on 2.0m (6.5ft) cable with mating adaptor for top setting wading rods. Hand display/processor unit includes LCD display, keypad interface, RS 232 interface, 2MB internal memory, 8 AA alkaline batteries, and temporarily submersible to 3 feet. Software package includes WadeADV for stream flow measurement, SonUtils and ViewArgonaut PC-based software for RS 232 communication. Also available as an option is a 2D/3D probe for the ADV for conversion to 2D/3D side looking flow measurements. The 3D portion of this probe allows measurement of water velocity in the vertical axis for special applications (ruggedized field version).
