Established in 1969, Valeport has grown its operations steadily over a period of four decades, giving us time to develop and perfect a whole series of high quality products aimed at critical industries. We’re now able to offer an expansive product range that includes the most reliable oceanographic, hydrographic and hydrometric instrumentation on the market.

In 2003, we finally outgrew the factory that we had been working from for 34 years, acquiring in its stead a state-of-the-art facility in which we develop, produce, calibrate and test all of our products. Each of these products has been developed in response to demand: we pride ourselves on our ability to take a market-led idea and turn it into a specification that can be realised by our expert team of mechanical, electronic, firmware and software R&D engineers.

The industries we serve require nothing less than perfection. That’s why we take every step to ensure the quality of our products remains as high as possible. The confidence that we place in the integrity our products allows us to offer a 3 year warranty with every device.

With excellent products comes an excellent level of service. As a 100% family owned business, we’re answerable to our customers alone, which means we act your best interests.

MIDAS WLR Water Level Recorder

The MIDAS WLR Water Level Recorder replaces the Model 730T as our Water Level Recorder/ Seabed Tide Gauge. The MIDAS WLR has been expertly designed to suit long or short term deployments in offshore environments or where traditional shore-based tide gauge is impractical. It can be moored in-line or to the seabed and is fitted with a 0.01% accuracy pressure sensor and acetal housing suitable for up to 500m depth rating. A deep water titanium housed option is also available.

MIDAS CTD+ Multiparameter Profiler

This innovative Multi-Parameter CTD features Valeport’s very latest 400 Series electronics, allowing it to sample all fitted sensors at exactly the same moment, at up to 8Hz. A range of standard sensors are available, and an advanced setup software allows for a wide variety of sampling regimes – including burst modes, delay starts, and conditional sampling. With an internal battery pack, up to 64mb memory, and a selection of real time output formats, the MIDAS CTD+ is ideal for both profiling and fixed mooring applications. You can find out more about the MIDAS CTD + by visiting the Valeport website, where datasheets and manuals can be downloaded.


We recognise the conflict faced by users who require the superior Sound Velocity data from an SVP yet still need the Salinity and Density data from a CTD. That’s why we developed the MIDAS SVX2, an instrument unique to Valeport that combines two technologies to give the best of both worlds. Fitted with a 0.01% pressure sensor as standard, the SVX2 uses synchronised sampling to give perfect profiles.  And, because our highly acclaimed digital “time of flight” SV sensor is the most accurate in the world, the user is also able to compare the true sound velocity data with that generated by commonly used equations. Find out more about the MIDAS SVX2 Combined CTD/SVP online at Valeport.co.uk.

MiniSVP Sound Velocity Profiler

This affordable Sound Velocity Profiler has been developed in order to make the most accurate SV measurements in the world available to everyone. The miniSVP is fitted with our world-renowned “time of flight” SV sensor, giving the very best results in Sound Velocity technology. Fitted with a single C cell and a large Flash memory, this unique device allows hundreds of profiles to be recorded. Meanwhile, the pre-programmed profiling patterns mean it can be set up and deployed extremely quickly and easily.

MiniSVS Sound Velocity Sensors

Our miniSVS Sound Velocity Sensors feature ‘time of flight’ technology to provide the lowest noise, highest accuracy and best resolution sound velocity data. This small instrument features sensor lengths in a range of sizes down to just 25mm and features an optional pressure or temperature sensor for versatility. Customers can also choose from a range of data formats to enable interface with existing systems.

VRS-20 Radar Level Sensor

The VRS-20 is able to work seamlessly with the TideMaster tide logger, interface with third party data loggers, and can also operate as a standalone unit with optional GPRS telemetry. Highly versatile and easy to install, this pulsed K-band radar level sensor has been developed to address a number of issues traditionally associated with water level measurement. Non-contact technology eliminates the installation, corrosion and fouling problems of submerged sensors while at the same time simplifying datum control. The VRS-20 also offers accuracy and performance that are unaffected by changes in atmospheric conditions and water density.

TideMaster Portable Tide Gauge

This compact and cost effective Water Level Recorder has been specifically designed by Valeport for applications where an accurate record of water height is required, but with the added option of taking meteorological data via an ultrasonic wind speed and direction sensor. The TideMaster Portable Tide Gauge is suitable for use in both fresh and salt water, and can be deployed for up to one year (dependant on sampling rate). Instrument setup and data retrieval are possible via an optional display panel or PC software. If required, the TideMaster can be fitted with radio modules for real time data transmission.

MIDAS DWR Directional Wave Recorder

Representing a significant stride forward in PUV wave recording technology, the MIDAS DWR (Directional Wave Recorder) is able to perform full onboard directional data analysis, in addition to the standard non-directional data that is offered by the MIDAS WTR. The DWR therefore allows the user to gather real time directional information at an unsurpassed 2° resolution. These unique features, along with many others, make the MIDAS Directional Wave Recorder the most cost-effective solution to directional wave monitoring requirements in shallow water coastal applications.

Model 106 Lightweight Current Meter

The Model 106 Lightweight Current Meter is a cost effective alternative to larger flow meters and is particularly suited for use in applications where the greater durability and depth rating of our larger meters are not necessary. Utilising Valeport’s standard 125mm diameter impeller, this lightweight current meter includes speed and direction parameters as standard, while further options for temperature and depth measurement may also be incorporated. Data gathered by Model 106, whether logged or real time, is fully compatible with our unique DataLog™ software. Manufactured from titanium and high grade polymers, the Model 106 is low in weight yet highly resistant to corrosion, making it ideal for coastal and estuarine applications.

MIDAS WTR Wave and Tide Recorder

The MIDAS WTR uses the time-proven Linear Wave Theory wave analysis method of measurement to deliver accurate results every time. This market-leading Wave Recorder benefits from our latest sensor measurement technology and features a 64 bit data processer. An improved range of sampling options, fast data upload, quick change battery carousel and intuitive operating software make the WTR one of the most versatile and easy to use pressure based wave recorders available on the market. Head directly to the Valeport website for more information, data sheets and user manuals.

Model 801 Electromagnetic Open Channel Flow Meter

Model 801 is a small solid-state sensor specifically designed for use in environments where fouling by weed or sewage can cause problems. Our extensive experience in electromagnetic technology has enabled us to build a highly precise instrument that can be totally relied upon to provide accurate readings (±0.5% of reading plus zero stability) over a wide flow range (±5 m/sec), in as little as 5cm of water. An integrated control display gives the user a choice of averaging modes, standard deviation of data, as well as an optional logging facility.
