Velocimeters
Digibar Pro
The Digibar Pro is the most cost-effective means of obtaining accurate water column sound velocities. Used primarily to calibrate acoustic systems, the Digibar Pro offers a fast and safe method for sound velocity calibration as compared to the traditional "bar-check". Regardless of sea state or current, the probe is simply lowered into the water to log sound velocity / depth samples (by time or depth interval) as the probe descends. The "sing-around" principle of velocity measurement automatically compensates for all influences including pressure, water salinity and temperature.
Digibar S
The rugged all stainless steel Digibar S was designed for un-tethered sound velocity casting. This configuration frees the probe from its electrical cable making deeper sound speed profiling a much easier and more reliable task. With a 500 m maximum depth capability and storage for multiple casts, the “S’s” flexible design still maintains some of the best features of the popular Digibar Pro. Immediately before the unit is deployed, a simple system of flashing LEDs serves to confirm battery status, pressure sensor status, and overall probe operation. The confirming indicators drastically reduce the possibility of retrieving a deployment only to find that there is no data to show for the effort. Logging parameters are setup via a simple
Windows interface communicating through your PC’s USB port. That same port is used to download the results of the cast and to charge the probe’s internal batteries. Cast data (sound velocity, temperature, pressure, and time) are stored internal to the probe in EEPROM. This means that critical measurements are maintained independently from the batteries that power the unit’s time of flight velocity determining circuitry, thereby providing an extra layer of security for the all-important cast results. Accurate, easy to use, rugged and reliable all appropriate descriptors of the Digibar S and the hallmark of Teledyne Odom’s product lines.
Digibar V
Designed to provide real-time velocity data to flat array type mulibeam systems, the small size and rugged construction of the Digibar V means it can easily be mounted near the sonar head. Sound velocity is derived using the time of flight measurement method and is accurate to within +/- 0.2 m/sec.
