The MIDAS DWR Directional Wave Recorder replaces the old Model 730D instrument, and represents a significant advance in PUV wave recording technology. As well as the standard non-directional data available from the MIDAS WTR, the MIDAS DWR also performs full onboard directional data analysis, allowing real time directional information at an unsurpassed 2° resolution. The unique features of the MIDAS DWR make it the most cost-effective solution to directional wave monitoring requirements in all shallow water coastal applications.

The MIDAS WTR Wave Recorder uses the proven Linear Wave Theory wave analysis method of measurement. The MIDAS WTR benefits from Valeport’s latest sensor measurement technology, together with 64 bit data processing, and an improved range of sampling options. Fast data upload, quick change battery carousel and intuitive operating software make the MIDAS WTR one of the most versatile yet easy to use pressure based wave recorders available.

A low cost, lightweight alternative to larger flow meters, ideal for use in applications where the superior durability and depth rating of Valeport`s larger meters is not necessary. Utilising the standard Valeport 125mm diameter impeller, the Model 106 features speed and direction parameters as standard, with further options of temperature and depth. Data (logged or real time) is compatible with Valeport`s DataLog software. The instrument is manufactured from titanium and polymers, giving excellent resistance to corrosion, whilst maintaining a small size and low weight. These features make the Model 106 the ideal instrument for coastal and estuarine applications, and other light duty survey work.

The VA500 Altimeter delivers a new approach to the problem of underwater positioning. State of the art signal processing offers unrivalled range and performance from a 500kHz transducer. Millimetre precision, 0.1m – 100m range, RS232/RS485/0-5V & 0-10V analogue outputs with a wide range power supply address the needs of the ROV, AUV and Hydrographic community in a compact, robust package.The option of integrating a high accuracy pressure sensor (0.01%) as used in the MiniIPS offers an unbeatable package for your underwater positioning requirements.

The BathyPack is one of Valeport`s premier MIDAS products, using state of the art sensors to generate precision Sound Velocity and Density profiles for highly accurate depth and height data. The simple top-end PC software, BathyLog, also allows all profile data to be used to monitor and correct multiple miniIPS pressure sensors, giving you the complete picture with one integrated sensor suite.

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 VRS-20 is a pulsed k-band radar level sensor developed by Valeport to work seamlessly with the TideMaster tide logger, operate standalone with optional integrated GPRS telemetry or interface to a third party data logger. Versatile and simple to install, the VRS-20 addresses a number of the issues traditionally associated with water level measurement.

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 an 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.

The miniTIDE is a small Tide Recorder, designed for short term underwater deployments. Fitted with a 0.01% temperature compensated piezo-resistive cell, the miniTIDE will record high accuracy pressure data for a period of 1 month at a 10 minute sampling interval, using a single alkaline C cell. This makes it ideal for use in short term projects or for academic studies. Available with a choice of pressure ranges, and with either 500m acetal or 6000m titanuim housings.

The MIDAS WLR replaces the popular Model 730T as Valeport`s Water Level Recorder / Seabed Tide Gauge. Designed for long or short term deployments in offshore environments, or locations where a traditional shore based tide gauge is impractical, the MIDAS WLR may be moored in line or to the seabed. The standard instrument is fitted with a 0.01% accuracy pressure sensor and acetal housing for up to 500m depth rating, with a deep water titanium housed option also available.
