Microflown
Microflown Technologies are based in the Netherlands and developed the unique Microflown probe which directly measures particle velocity. Any sound field is described by two complementary acoustic properties, the scalar value ‘sound pressure ‘and the vector value ‘particle velocity’. In the acoustic near field, acoustic particle velocity is the dominant acoustic property.
The Microflown is the world’s first and only MEMS technology based sensor that can measure acoustic particle velocity. By measuring the temperature difference across two extremely thin platinum wires placed in parallel, this extremely fast mass flow sensor is capable of monitoring the movement of air particles.
