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.

New Svantek Product: Introducing the SV 810 Air Overpressure Meter
September 2, 2026
When it comes to blast monitoring, accurate measurement of air overpressure is just as important as monitoring ground vibration. Blast events can generate significant pressure waves, particularly at low frequencies. That’s where the new SV 810 Air-Overpressure Meter from Svantek comes in. Designed specifically for blast monitoring applications, the SV…
