I have a datasheet of snowpack depth by using a Campbell SR50 Sonic sensor. But even after read the manual, it's not clear for me what's the depth of the snowpack. Can someone help me with this?
The SR50 measure elapsed time between emission and return of an ultrasonic pulse. An independent air temperature measurement is required for data correction for variations of the speed of sound in air. It is sensor only. I addition you must have time measurement device to obtain full result in cm (m, inch etc)
