Environmental Monitoring Solutions Since 1925 Sound electronic filtering Self-correction of the measurement for compensation of the air temperature Compact and affordable

TNU sensors capture snow level up to either 4 or 8 meters, according to the model in use (TNU04, TNU08). Functioning system is related to the emission of short ultrasonic frequency pulses towards the depth of snow to investigate and to the subsequent reception of the reflected wave, generated once the pulses reach the surface the snow is lying on. It ensures excellent performance for what concerns accuracy, thanks to a system of self-correction of the level measurement. Indeed, by means of an integrated temperature sensor, it can easily take into account the variation of the sound speed as a...
