Snow/Water Depth Sensor

Campbell Scientific

The SR50A is a new generation acoustic snow/water depth sensor measuring time of flight to determine snow depth or water level. The sensor uses a multiple echo processing algorithm to help ensure measurement accuracy. It is designed to work in the extreme conditions where the measurement of snow depth is likely to be required. The unit is mounted facing down to the ground before any snow falls to determine the sensor to ground height, then as snow falls the sensor measures the rise and fall in surface height. SDI-12, RS-232, and RS-485 output options are available for measuring the SR50A.
