It uses a
transmissometer, but is more accurate than RVV since RVV is not based on visible targets.
Quantifying the response of optical backscatter devices and
transmissometers to variations in suspended particulate matter.
At Maastricht, the company plans to show its AWOS, ATIS and RVR (
transmissometer) solutions from the Metworx range.
The sensor types endorsed by ICAO are the
transmissometer and the forward scatter sensor.
The first involved installing and commissioning
transmissometers to measure the visibility alongside the runway.
Currently, predominant monitoring means include satellites, visibility sensors,
transmissometers, and human-based observations.
The need to identify sources of error with the development of new fisheries technologies is documented in genetic studies (Blanca et al., 2009), in mark and recapture studies (Curtis, 2006), in the tracking of vessels with global position systems (GPS) (Palmer, 2008) and in measuring water clarity with beam
transmissometers (Larson et al., 2007).
Pairing scientists with engineers, the 40-employee company makes fluorometers,
transmissometers, scattering sensors and spectrophotometers, all of which collect data from the ocean and beam the information back to the surface, helping scientists learn about important changes in the food chain.
