QUALITY UNDERWATER INSTRUMENTATION
Key to any Hydrographic survey is tidal data and Valeport offer tide gauge options for both shore based and offshore / seabed applications together with telemetry packages for secure data transfer.
Echo sounders, both single and multi-beam need sound velocity data to correctly produce depth measurements. Valeport offer the largest range in sound velocity sensors and profilers that have world beating accuracy.
If simple, small boat echo sounding is required with single or dual frequency transducers and interface of external parameters with GPS reference then we have just what you need in our portable Midas Surveyor single beam echo sounder.
See our Hydrographic Survey Case Studies:
The MIDAS Surveyor has been designed to offer a low cost solution for small scale hydrographic surveys.
The system is supplied with a 210kHz transducer as standard, and uses Valeport's own advanced digital signal processing techniques to ensure high accuracy and reliable bottom tracking. With an integral SBAS enabled DGPS receiver, the MIDAS Surveyor will log position and depth data for over 30 hours, as well as performing on-line correction using external heave and tide data inputs.
Options include an additional 33kHz transducer, or high accuracy 16 channel DGPS receiver.
The miniSVP is a new 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.
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.
SWiFTplus combines wide range Turbidity observations with Valeport’s survey grade sound speed, temperature and pressure 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 an App and instantly shared, in industry standard SVP formats through email and cloud services.
The TideMaster is a small, cost effective Water Level Recorder, specifically designed for applications where the user requires an accurate record of water height, but with the added option of meteorological data via a ultrasonic wind speed and direction sensor.
Suitable for use in fresh or salt water, the TideMaster can be deployed for up to 1 year, dependant on the sampling rate, with instrument set up and data retrieval via an optional display panel or using the PC software supplied. Alternatively, the system can be supplied with radio modules for real time data transmission.
TideStation has the TideMaster Tide Gauge as its core - Valeport’s industry leading Tide Gauge system.
Offering Pressure, Radar and hybrid tidal observation techniques coupled with interfaces to other meteorological and 3rd party systems. All data can be recorded locally and broadcast to a central command and control point as required. Within the TideStation enclosure you will find all required ancillary infrastructure to maintain power to the Tide and Met equipment interfaced and your chosen communications systems.
A portable survey solution for monitoring of Tide, Met and other sensors. Housed in a large rugged ABS case, the TideStation (Portable) offers a choice of either UHF or GPRS telemetry, with connection to Pressure or Radar sensors along with interface to other meteorological systems. Data is recorded locally and broadcast to base stations as required.
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.
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.
The VRS-20 is a pulsed K-band radar level sensor developed by Valeport to work seamlessly with the TideMaster Tide Display/Logger and other third party data loggers using RS232, RS485 and SDI-12 communication.
Versatile and simple to install, the VRS-20 addresses a number of the issues traditionally associated with water level measurement. Non-contact technology removes the installation, corrosion & fouling issues of submerged sensors, while simplifying datum control. Accuracy and performance are unaffected by changes in water density and atmospheric conditions.
