Snow blown through a sharp-edged frame, 5 cm wide and extending 50 cm above the ice on a frozen lake, is trapped by a porous fabric bag. Wind shakes the snow from the bag into a 100-liter container in a steel casement beneath the surface, where it is weighed by an electronic balance. Connection to a remote computer allows 15 second readings of drift flux. The device provided excellent measurements during 236 runs of 5-min duration, in blizzards with transport rates as high as 300 g/m-s.
