miniSVP – Sound Velocity Profiler

The miniSVP, a budget Sound Velocity Profiler designed to make the best SV measurements in the world available to everyone.

Featuring Valeport’s unique acclaimed “time of flight” SV sensor, the miniSVP is available in either 500m rated acetal or 6000m rated titanium versions. A single C cell and large Flash memory allow hundreds of profiles to be recorded, and the pre-programmed profiling patterns allow it to be set up and deployed quickly and easily.

Data Acquisition

Features a selection of pre-programmed sampling regimes, covering many standard applications. Data may be sampled from 1 to 16Hz, making it suitable for rapid profiling or for continuous measurement at a fixed point.

Sampling Modes

Continuous:
Regular output from all sensors at 1, 2, 4, 8 or 16Hz.
Profile:
Logs data as the device falls (or rises) by a defined
amount through the water column.

Communications

Will operate autonomously, with setup and data extraction performed by direct communications with PC. Operates in real time, with a choice of communication protocols fitted as standard and selected by pin choice on the output connector

RS232:
Up to 200m cable, direct to serial port
RS485:
Up to 1000m cable
