Power and Communication Cable
The power and communication cable is connected to the end bell con-
nector. The cable supplies external DC power (15–48 V) and provides
two-way serial communication with an external computer.
The cable also provides synchronization options when the Vectrino
Profiler is used as master or slave to synchronize measurements with
other Vectrino Profiler’s and/or other instruments.
Cable Wiring. By default, the Vectrino Profiler is shipped with a 12-pin
connector and cable. The connector type is either a splash-proof
connector or an MCBH-12-FS waterproof connector. The Vectrino
Profiler power lines are diode protected, hence, you do not have to
worry about wiring the Vectrino Profiler power backwards. If you do, it
will not damage your instrument. The pin-out is shown in the side

Functional Description
This section briefly describes some of the underlying principles that
control the operation and application of the Vectrino Profiler
velocimeter.
The Vectrino Profiler has two modes of operation:
• Command mode. In command mode the Vectrino Profiler is ready
to accept your instructions.
• Data Acquisition Mode. The Vectrino Profiler enters data acquisition
mode when you click any of the Start commands (e.g. Start Data
Collection) in the Vectrino Profiler software. The Vectrino Profiler
collects data without interruption.
Doppler Theory
Sound does not reflect from
water, but from particles
suspended in the water. These
particles are typically
suspended sediment or seeding
particles, and move with the
same average speed as the
water. The velocity that is
measured is consequently the
velocity of the water.
The Vectrino Profiler uses the Doppler effect to measure current
velocity. The Doppler effect is the change in pitch that is heard when
either the source of a sound or the listener is in motion. When you
hear a vehicle with a siren, the pitch is higher when the vehicle is
heading towards you, and lower when it is going away. The change in
pitch tells you how fast the vehicle is moving.
The Vectrino Profiler transmits short pairs of sound pulses, listens to
their echoes, and, ultimately, measures the change in pitch or
frequency of the returned sound.
Vectrino Profiler
13
The Vectrino Profiler
velocimeter operating
principle: A pulse is
transmitted from the centre
transducer, and the Doppler
shift introduced by the
reflections from particles
suspended in the water, is
picked up by the four
receivers.
SNR Sweet Spot: The
profiling range of the
Vectrino II is ultimately
controlled by SNR. The SNR
is highest at the sweet spot,
located 5 cm from the
transmitter. The best profiling
range is a region centered on
this sweet spot location.
The transmit/receive beam
pair is sensitive to velocity in
the direction of the angular
bisector between the beams.
The arrow indicates a
positive velocity. Since the
receive beams are slanted
at 30°, all three beam pairs
measure velocity that is 15°
away from the transmit
beam.
Vectrino Sonar Principles
In contrast to standard Doppler profilers and current meters, the
Vectrino is a bistatic sonar. This means that it uses separate transmit
and receive beams. It transmits through a central beam and receives
through four beams displaced off to the side. The figure below shows
how the beams intersect each other 50 mm from the transmitter. The
measurement profile is defined by this intersection and by range
gating in time. The transmit transducer sends a short pulse that
transits the profiling region of approximately 30-80 mm and the
receivers listen to echoes returned from this pulse gated in time. The
Vectrino uses four receivers, all focused on the same volume, to
obtain the three velocity components from that very volume.
The figure below shows that a transmit/receive beam pair is sensitive
to velocity in the direction of the angular bisector between the beams.
The arrow indicates a positive velocity.
14
Chapter 5
Software
The arm with the marking
defines the X-direction. The
Z-direction is towards the
electronics of the Vectrino.
Coordinate System
The Vectrino measures velocity components parallel to its three
beams, or in beam components. It reports data in Beam or XYZ
coordinate systems.
The XYZ coordinates are relative to the probe and independent of
whether the Vectrino points up or down.
In XYZ coordinates, a positive velocity in the X-direction goes in the
direction of the X-axis arrow.
Velocity Uncertainty
The Vectrino velocity is an average of many velocity estimates (called
pings). The uncertainty of each ping is dominated by the short term
error. We reduce the measurement uncertainty by averaging together
many pings. There is a limit to how much you can reduce your
uncertainty. We call this limit the long-term bias. The long-term bias
depends on internal signal processing, especially filters, and on the
beam geometry. The long-term bias in the Vectrino is typically a
fraction of 1 cm/s. The short-term error of a single ping depends on
the size of the transmit pulse, the measurement volume, and the
beam geometry. Averaging multiple pings reduces errors according to
the formula:
where σ is the standard deviation and N is the number pings
averaged together.
Note: The Vectrino software minimizes the instrumental error only. In

many situations, the environmental turbulence or surface waves will
dominate the short term velocity fluctuations.
Data Handling
The Vectrino Profiler software saves data in binary files, which are
easily converted to Matlab structured arrays or ASCII format files,
using the conversion module in the software.
Matlab:
• The *.mat file contains Data and Config structured arrays. Each
array contains a “Comments” and “Units” field that describe the
contents of each structure.
ASCII:
• The *.hdr file is a self-documented table.
• The *.dat file contains velocity data at the full sample rate.
ASCII files are easily imported into most spreadsheets and data
analysis programs.

Software
This chapter provides you with basic information about the software,
installation of the software and its configuration. For further
information, about the software, its configuration and use, please see
the Help function in the Vectrino Profiler software.
Please see the Software Users Guide for more information on how to
use the software.
Installation
The Vectrino Profiler acquisition software on the included memory stick
requires a Java virtual machine (JVM) to operate. The software has been
tested with the Sun JVM available from http://www.java.com/ but is also
known to be fully functional with other JVMs. To install the software,
double click on Vectrino Profiler_setup.exe . This will copy the
appropriate files to the installation directory and create a shortcut to
the application on the desktop.
PDF versions of both manuals will be copied into the install directory
when the software is first executed. More information on installation is
available in the software user guide.
Licensing
The firmware supports several functionally different variants based
upon a license key which is provided when the instrument is purchased.

Mounting Guidelines
Follow these guidelines when you mount your Vectrino Profiler.
What to consider
• Make sure that there are no obstructions between the sensor and the
focal point (sampling volume) located about 5 cm from the
transducers.
Note: When mounting your
Vectrino Profiler, use the
recessions to strap it to the
structure. Never use the probe
stem as mounting point.
• Consider the effects of large objects on the flow itself. A rough rule
of thumb is that objects disturb the flow as far as 10 diameters away
from the object. Flow disturbance is greatest directly downstream in
the wake behind the object.
• All acoustic transducers must be submerged during data collection.
Operating your Vectrino Profiler when the transducers are out of
water will not cause any damage, but your data will be meaningless.
For side-looking probes, it is possible to collect 2D-data with only
the lower receiver arms submerged.
• The best quality is achieved if the main flow direction is
perpendicular to the transmit axis. Flow directly into the transmit
axis should be avoided.
• Make sure your mounting structure is stable. Small vibrations in the
mount can generate large accelerations in the data.

Test and Verification
Verify that your equipment is working as expected.
Communication
Check that you have installed the software correctly according to the
procedure in chapter 5, Software, and then follow this procedure to test the
communication:
1 Using the enclosed cables, plug in the AC adapter, and connect the
Vectrino Profiler cable and USB converter to the USB port on your
computer
2 Start the Vectrino Profiler software
3 Click on Connect: Vectrino Profiler
4 Select the appropriate serial port and communication speed
5 Click on Apply to initiate communications with the instrument
Transducers
1 Fill a bucket with water and a little dirt (as sound-scattering material).
2 Click the Start Collecting Data button. While the transducers are in the air,
the velocity measurement will look like random noise.
3 Immerse the transducers in the water, and observe the velocity, the
standard deviation, and the amplitude. Note the change in the graphical
view of the velocity when the probe is lowered into the water. In the air the
20
Chapter 5
Software
graphs are noisy; in water they should be smooth.
Measurement in air

graph) and in water
(right part of the

Noisy velocity
graphs: If the
velocity graphs
remain noisy when
the probe is
immersed in water,
try varying the
position of the
probe, or add some
seeding like dirt or
small particles to the
water.
Probe Check
Previous generations of the Vectrino velocimeter used a separate Probe Check
mode to verify the integrity of the instrument. When licensed for profiling, the
Vectrino Profiler collects amplitude profiles from the beams (showing how the
signal varies with range) as part of its normal operation. For single
measurement licensed instruments, a “beam check” mode is provided which
produces an equivalent amplitude profile for a range up to 30cm. Amplitude
profiles can be used to diagnose and correct problems and to optimize data
collection.
Vectrino
21
Signal-to-noise
ratio:
The signal-to-noise
ratio (SNR) is
defined as follows:
)
Strictly speaking,
some noise will
always be present,
so Amplitudesignal
should read
Amplitudesignal + noise.
However, for SNR
values in the
magnitude
applicable to typical
Vectrino Profiler
situations, the
difference is
negligible.
To check probe operation:
1 Make sure the probe is submerged in water with the transducers within 20
cm of the bottom.
2 Enable the Probe Check option in the configuration.
3 Click the Start Data Collection button.
The four colored graphs in the profile display window on the left correspond to
each of the four receive beams.
There are two peaks visible in the amplitude data. The broad peak centered at
~5cm is the valid profiling volume. The sharper secondary peak (located at
~19 cm in this data set) is the bottom return.

Chapter 8
Synchronizing Multiple
Instruments
Your Vectrino Profiler can serve as master for other Vectrino Profiler’s,
or its sampling can be controlled by other sensors. This comes in
handy when you need to use several Vectrino Profilers for a single set
of measurements.
If you connect a controller to the Vectrino Profiler, you can set up a
fairly sophisticated system in which the controller can power the
Vectrino Profiler and provide it with sync pulses to control the
sampling accurately. The controller can serve as a storage device.
Note: On some older
instruments the sync lines are
labeled Sync in and Sync out.
These should be treated as
Sync– (Sync In) and Sync+
(Sync Out).
Your Vectrino Profiler can be synchronized with other instruments via
a pair of sync lines. To avoid noise problems and to make cabling
easier, the two sync lines use an RS-485 chip which is balanced and
bi-directional.
The sync lines are labeled Sync– (n) and Sync+ (p).
Synchronizing Multiple Vectrino Profilers
1 Connect all the Sync+ lines together and all the Sync– lines
together. All instruments should share a common ground.
2 Select one instrument as the master and the rest as slaves (Input
sync) in the software.
3 Start data collection in all slaves (click the Start Collecting Data
icon) before starting the master. The slaves will then wait for the
Vectrino
23
first sync pulse from the master before sampling commences.
If you use Sample on sync, all instruments should be configured with
the same sampling rate.
Synchronizing From a TTL Source
TTL signal levels can be mixed with the RS-485 levels of the Vectrino
Profiler.
Connect your sync pulse (0 – V volts) to Sync- and connect Sync+ to a
constant voltage V/2 (where V is the ON voltage of the sync pulse).
This provides a defined transition when the TTL signal changes, which
is not the case if you ground Sync+. The SYNC inputs are diode
limited to 5V through a 4.7 ohm resistor. Input voltages above 5V are
not recommended for use.
RS485 levels: These differential
levels define the signal the
Vectrino Profiler reads for Input
Sync:
High level: Sync- > Sync+ by
200 mV
Low level: Sync- < Sync+ by
200 mV
Noise problems: If you
encounter noise problems, try
terminating the Sync- line at the
TTL input by connecting a 120
ohm resistor in series with a 1nF
capacitor between the Sync-
line and ground. The best
solution for external sync is
using RS485 as the input /
output device.
Note: This implies that a
Vectrino Profiler can operate as
a master for a Vector, but the
opposite is not possible.
When the Vectrino Profiler functions as master, the Sync- line can be
connected to the TTL input and the two systems must be connected
so they share common ground.
How Synchronization Works
Output Sync
(operating as the master) transmits a pulse with a
duration of 50 µs. The Vectrino Profiler transmits a pulse at the end of
the sampling interval and a single pulse at the beginning of the first
sampling interval to start everything when in “Master (Vectrino)”
mode. When in “Master (Other)” mode, a pulse is transmitted in the
middle of each sampling interval.
Input Sync
triggers on the falling edge of the Sync+ / Sync- signal.
After each trigger the input is discarded for the next 100 µs.

Chapter 9
Maintenance
Before you assemble a system that involves custom cables, power
supplies or the like, first assemble and test the Vectrino Profiler using
just the cables and power supply that came with the system. This is
the easiest way to get the system up and working. If you encounter
problems, you can always return to this setup to confirm that they are
not caused by a faulty instrument.
Preventive Maintenance
Preventive maintenance is your primary tool to keep your Vectrino
Profiler in shape and ready for action and deployment.
Clean your Vectrino Profiler Velocimeter regularly. Use a mild
detergent, and pay special attention to the transducers.
Corrective Maintenance
Only qualified personnel are allowed to perform corrective mainte-
nance activities. Please refer to the separate service manual or contact
Nortek for further assistance.

lost or damaged, as Nortek AS does not cover freight insurance on
repairs.
Nortek AS is not responsible for instruments damaged or lost in
transit. Nor shall we be held responsible for consequential damage as
a result of instruments being damaged or lost in transit.
Nortek AS will insure the instrument upon returning the goods to you.
We will bill you for the insurance along with the costs for repair and

freight.
For warranty repairs, the transport and freight insurance from Nortek
AS to you will be covered by Nortek AS.
Customs regulations
The regulations and requirements covering the export and re-import
of items sent for repair varies from country to country. In the past,
some of our customers have experienced problems because they have
failed to provide the proper documentation. If these matters are not
managed correctly, you may be charged import duties and taxes for a
second time when your instrument is returned to you.
At Nortek we must meet our own country’s regulations when
instruments are repaired and subsequently returned. This, however,
may not be sufficient for your country.
To avoid problems, we strongly recommend that you, as part of your
own procedures for handling returns, always check with your customs
authorities as to what information, documents etc. they need from
you and from us. Then let us know what you need from us by e-mail,
fax or mail. We will do our very best to help you.
