Valeport Sound Velocity Sensors

Valeport are the world leaders in Sound Velocity technology - a position achieved by both innovative development and meticulous attention to detail throughout the design, manufacture and especially calibration processes.

Having been established at the forefront of this field nearly a decade ago with Digital Time of Flight technology, Valeport have now made a series of incremental changes to reinforce that position, ensuring that Valeport SV sensors offer levels of performance that are demonstrably far in excess of even the latest offerings from competitors.

  • Genuine Accuracy of ±0.02m/s (Total Error Budget)
  • Precision (peak to peak noise) of ±0.002m/s
  • Operating range of 1375m/s to 1900m/s (covering all environments from fresh water to the Dead Sea and the Marianas Trench)
  • Data rates up to 60Hz (instrument dependent)

 

Product Range:

miniSVP

The miniSVP is 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 setup and deployed quickly and easily.

MIDAS SVP

The MIDAS SVP gives the most accurate Sound Velocity Profiles currently possible. As well as using the world leading digital time of flight sound speed sensor, this instrument also has a ±0.01% pressure sensor, and features Valeport's synchronised sampling technique to guarantee that all sensors are sampled at exactly the same point during a profile. Titanium construction and a large memory make it suitable for rapid profiling down to 6000m depth.

MIDAS Combined SVP/CTD

The MIDAS SVX2 is the latest version of Valeport's unique instrument. Recognising the conflict faced by users requiring the superior Sound Velocity data from an SVP, but still needing the Salinity and Density data from a CTD, the MIDAS SVX2 combines both technologies to give the best of both worlds. Now fitted with a 0.01% pressure sensor as standard, the SVX2 also uses synchronised sampling to ensure perfect profiles, and since the digital time of flight SV sensor is the most accurate in the world, it's also possible to compare the true sound velocity data with that generated by commonly used equations.

UV-SVP

Based on the Valeport miniSVS, the UV-SVP offers a form-factor designed for Underwater Vehicles where space is at a premium. Incorporating Valeport's class leading time of flight sound speed sensor, a PRT temperature sensor and a 0.01% pressure sensor in a compact package weighing just 750 grams (in air), the lightweight titanium housing gives a depth rating of 3000m. A wide range (9-30V DC) isolated power supply and RS232 communications complete the package.

SWiFT & SWiFT Plus SVP

Designed from the outset with the intention of a seamless workflow, the SWiFT SVP has integral GPS to geo-locate every profile. This new compact unit features high accuracy SV, Pressure and Temperature as you would expect, plus integral GPS, re-chargeable battery, LED status indications for GPS, battery and communications.

The SWiFT Plus SVP includes turbidity measurement as well as sound speed, temperature and pressure. This turbidity sensor addition is effectively two sensors in one. The first is a "classic" turbidity sensor (nephelometry using a 90˚ beam angle) for low turbidity levels (0-2000 NTU) and the second uses an OBS optical backscatter arrangement (~120˚ beam angle for optical backscatter) at high turbidity levels (>20,000 NTU).

Rapid SV

The Valeport rapidSV profiler has been developed for the fast collection of Sound Velocity Profiles, without compromising the quality of the data. The world's most accurate Sound Velocity sensor with virtually instantaneous response time, data acquisition rates of up to 32Hz housed in a low drag housing result in the highest quality profiles at drop rates over 5 m/s. Used as the probe with the Oceanscience Group underwaySV profiler system for near real time profiles of sound velocity without stopping the vessel.

Ultra SV

Ultra-fast, ultra-compact, ultra-dependable. The next generation of sound velocity sensor. Redesigned from the connector up, the UltraSV offers a truly smart and exchangeable sound velocity sensor without compromise.

miniSVS

The miniSVS Sound Velocity Sensors use state of the art digital "time of flight" technology to provide the lowest noise, highest accuracy, best resolution sound velocity data available. Small size and a choice of sensor lengths down to just 25mm make the sensor suitable for a variety of applications, and the optional pressure or temperature sensor adds versatility. There is a choice of data formats to allow interface to existing systems.
