Acoustic Doppler Meters
 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.

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.

ADCP MOUNTING AND DEPLOYMENT HARDWARE:
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.

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.

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.

 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.

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).
