MAVS-3
Vector
Averaging 3 Axis Acoustic Current Meter
With Long Term Deployment Capability
The MAVS Current Meter is a true three axis acoustic current meter which employs a differential travel time measurement technique. The current meter takes measurements across four acoustic axes to provide a true vector averaged velocity measurement. Programmable burst mode and triggered sampling provide the most flexible current meter available.
The
combination of small sensor geometry and differential travel time technique
provide unsurpassed resolution and accuracy. The small transducer size significantly
reduces the disturbance to water flow. While the standard range of measurement
is 200 cm/sec, low speed measurement accuracy in the 0.03 cm/sec to 10 cm/sec
range is preserved.
MAVS-3 includes MAVSOFT Win95, Win98, WinNT user interface. Standard, commercially available software such as TTOOLS or PROCOMM may be used to communicate with the MAVS-3 for getting real time data or for downloading and archiving recorded data to a PC. Software such as MATLAB, Excel, Quattro Pro and Lotus 123 may be used for tabular display and graphing data.
The MAVS-3 employs a faired sensor head design with central strut and a 9.5 cm acoustic path length. The controller is an Onset Tattletale 8 which is mounted by a connector beneath the main circuit board. A battery pack comprising 18 AA alkaline cells provides all the necessary power to the instrument. A 4 pin connector mounted on the top end cap permits external power to be applied and provides TTL level, RS-232 or RS-485 communication capability.
