| Technology & Benefits
Acoustic Phase-Shift Transit-Time Technology
• Eight transducers define four acoustic transit-time paths
• Accurate even near surface and seabed
• Accurate low- and high-velocity measurement
• Measures very clear as well as turbid water
(no reflectors required)
• Economical 2 or 3 dimensional point velocity
(X,Y converted to N,E using compass/tilt sensors)
• Internal recording and real-time output
• Optional CTD for salinity/sound velocity
|
Product Features
• Compact, lightweight, low-maintenance construction
• Simple to operate
• 2- or 3-axis true cosine response velocity measurement
• Accurate velocity measurement with excellent low-velocity resolution
• Built-in compass with 2-axis tilt sensor
• Temperature measurement capability
• Extremely long battery life with low-maintenance alkaline batteries
• Real-time output/display capability
• Averaged and/or burst data output
• Long-term data logging to internal flash memory
• ASCII serial data output via RS-232 or RS-485
• Built-in real-time clock with on/off power control
• 1.5-ton working strength mooring frame (optional 5-ton mooring frame)
• Optional conductivity, temperature, pressure sensor package may be added
• Optional Analog DC channel inputs for external sensors (e.g. turbidity, oxygen)
• Choice of epoxy shallow-water or titanium deep-water housings
