Valeport is the UK's leading manufacturer of hydrometric and oceanographic instrumentation. Valeport was established in Dartmouth in 1969 with a small product range based around the 'Braystoke' impeller flow meters.
Valeport is committed to continually develop and manufacture the highest quality products for the hydrometric, hydrographic and oceanographic communities:
Valeport Tide Gauges
Model 740 Portable Tide Gauges
The Model 740 is a small, cost effective Water Level Recorder, specifically designed for applications where the user simply requires an accurate record of water height, rather than the more sophisticated tide gauge that Valeport offers. Suitable for use in fresh or salt water, the 740 can be deployed for up to 2 years, dependant on the sampling rate, with instrument set up and data retrieval via PC software supplied. Alternatively, the system can be supplied with radio modules for real time data transmission.
MIDAS TMS Tide Gauges & Environmental Monitoring System
The MIDAS TMS represents an evolution in the field of Tide Gauges and Environmental Monitoring Stations. Based on Valeport’s proven data acquisition techniques, the MIDAS TMS can be configured with a wide selection of commonly used sensors. Features such as touch screen operation and rugged environmental housing make it ideal for stand alone applications, but it can just as easily become an integrated part of your LAN, with ethernet, WiFi, radio and dial up communications options.
MIDAS WLR Water Level Recorder
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 resonant quartz pressure sensor and acetal housing for a 500psi (350m) depth rating, with a deep water titanium housed option also available. A slightly less accurate 0.04% strain gauge transducer offers an excellent cost-effective alternative. The MIDAS WLR also has a range of real time data output options, including FSK communications over cable lengths up to 6km.
Valeport Wave Recorders
MIDAS WTR Wave & Tide Recorder
The MIDAS WTR replaces the popular Model 730W wave recorder, and is one of the most sophisticated pressure based wave recorders available. Powerful onboard data processing uses Linear Wave Theory to give a real time output of wave height and period, together with full spectral analysis. The intuitive setup software allows complex regimes of up to 4096 data points to be analysed, at frequencies up to 8Hz. Quick change battery carousel, USB data upload, large memory, and high accuracy sensors complete the package.
MIDAS DWR Directional Wave Recorder
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.
Model 750 Data Telemetry Buoy
The Model 750 Telemetry Buoy is the ideal accessory for Valeport's Wave Recorders, and other Valeport instrumentation, with its fully bi-directional UHF link between instrument and PC. The buoy is of classic spar design, with a rigid floatation unit. All electronics and battery are held in a submerged stainless steel pod, which also has a connector for communications with the instrument, and mounting points for a strain cable. With an omnidirectional antenna and selectable frequency within the 458.5 - 458.9MHz band, data transmission of up to 20km can be acheived (with clear line of sight). The receiver unit, supplied with a 3dB antenna, plugs directly into the user's PC and communications are established using Valeport's standard Windows based software packages. GSM and VHF versions are also available.
Ocean Engineering
MIDAS 400 Customised Data Acquisition Package
The MIDAS 400 (Multi-Input Data Acquisition System) is a more than just a logger - it is a complete sensor control and data acquisition system, customised to each client's individual specifications. At the heart of the system is Valeport's "400 series" processor. A large range of standard oceanographic sensors may be added to the system in a "plug and play" style, using a series of dedicated interface boards. In this way, an individually tailored suite of sensors can be controlled by a single standard software package, providing features such as synchronised sampling, conditional sampling, delay start and secondary calibrations. A choice of standard housing materials is available, including anodised aluminium and titanium, or alternatively shore based or OEM configurations can be supplied.
Modus IPS Intelligent Pressure Sensor
The Modus IPS incorporates a resonant quartz intelligent pressure sensor to provide high accuracy depth information. A selection of sample rates is available up to 8Hz, together with a choice of digital output formats (RS232, RS485 and RS422). Multiple sensors may be used with a single PC running BathyLog or IPSLog software to give differential measurements for precise positioning.
