SWiFT SVP - Sound Velocity Profiler
Page 7
3. SWiFT SVP - Sound Velocity Profiler
Designed from the outset with the intention of a seamless workflow, the SWiFT profiler provides survey-grade
sensor technology coupled with the convenience of Bluetooth connectivity and rechargeable batteries. An integral
GPS module, to geo-locate each profile, completes the package. Data can be easily and quickly downloaded and
reviewed wirelessly, via Bluetooth, using the either Valeport's Connect PC software or the SWiFT App for iOS
portable devices and instantly shared, in industry standard SVP formats through email and cloud services. Using
the provided USB adapter or cable, Valeport’s Connect software package provides further tools.
In addition to the directly measured sound speed, temperature and pressure observations, Conductivity, Salinity
and Density are calculated using Valeport’s proprietary algorithm developed from extensive laboratory and field
work.
With an operational battery life of up to 5 days and the convenience of charging via USB, SWiFT is intended for
coastal, harbour and inland hydrographic survey use and offers the highest quality sound velocity profiles in a
compact, robust and portable package.
Key Features
1. Self contained, sound velocity, temperature and
pressure profiling system
1.1. From measured observations conductivity,
salinity and density can be calculated
2. Lithium Ion rechargeable battery

4. LED symbols to identify:
4.1. Instrument status
4.2. Battery Status
4.3. GPS Status
4.4. Bluetooth Status
5. Bluetooth connectivity to PC & iOS App.
6. Automatic reacquisition of Bluetooth connection
and file down load on recovery
7. GPS Geo-Location and time
8. Deployment weight that will not interfere with
sensor performance

5. Sensors
5.1. Sound Velocity Measurement
Utilising Valeport's latest design for the world's most accurate sound velocity sensor, each measurement is made
using a single pulse of sound travelling over a precisely known distance, so is independent of the inherent
calculation errors present in CTD calculated data. Valeport's unique digital signal processing technique virtually
eliminates signal noise, and gives almost instantaneous response; the digital measurement is also entirely linear,
giving predictable performance under all conditions.

5.4. Optical Sensors
An optical sensor must be kept clean to operate correctly. Ensure that the SWiFT is powered down before
cleaning the sensor.
Use warm soapy water with a soft bristled brush to remove any light fouling.
For heavy fouling use a solvent (e.g Isopropyl alcohol) and a soft bristled brush.
Always rinse thoroughly after every use in clean, fresh water.
5.4.1. Fluorometers
5.4.1.1. Safety Statement
A Valeport Fluorometer is classified as Risk Group 1 under standard 62471. As the type is classified as Risk Group 1
solely due to radiation in the visible band a hazard label is not required. However,
·the LED used is in excess of the Exempt Group and that the viewer- related risk is dependent upon how the user
installs and operates the equipment.
·the exposure hazard value (EHV) for a Valeport Fluorometer in terms of distance is 320mm.
Never look directly into the optical aperture
