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 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. 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. 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. 13 14 Chapter 5 Software Coordinate System 30o The Vectrino measures velocity components parallel to its three beams, or in beam components. It reports data in Beam or XYZ coordinate systems. The arm with the marking defines the X-direction. The Z-direction is towards the electronics of the Vectrino. Z Z X X View direction Y 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: 𝛔𝐕𝐦𝐞𝐚𝐧 = where σ 𝛔𝐕𝐩𝐢𝐧𝐠 √𝐍 is the standard deviation and N is the number pings averaged together. Note: The Vectrino software minimizes the instrumental error only. In Vectrino Profiler 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. 15 16 Chapter 5 Software Chapter 5 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. The currently supported variants are: Vectrino Profiler Variant Number Velocity Maximum Adaptive Bottom Name of Sampling Velocity Config Check Velocity rate (Hz) Range Yes Yes Cells Profiler Vectrino- Full (m/s) 100 3.0 profile amplitude range profile 1 200 5.0 Yes Yes 1 200 5.0 No No 1 25 1.0 No No ProfilerB+ VectrinoProfiler+ VectrinoProfiler with 17 18 Chapter 5 Software Chapter 6 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. • Consider the effects of large objects on the flow itself. A rough rule Note: When mounting your Vectrino Profiler, use the recessions to strap it to the structure. Never use the probe stem as mounting point. 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. Vectrino 19 Chapter 7 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 (left part of the graph) and in water (right part of the graph). 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 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. Signal-to-noise ratio: The signal-to-noise ratio (SNR) is defined as follows: SNR = Amplitudesignal 20log10 ( Amplitudenoise ) 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. 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. 22 Chapter 5 Software 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 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 Syncline 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. 23 24 Chapter 5 Software 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 maintenance activities.
