Overview

The SnowVue™10 is a digital, ultrasonic snow-depth sensor that provides continuous and accurate snow-depth measurements with its advanced spectrum analysis and best-in-class, wide-band transducer. With its low-power requirement and low-maintenance design, the SnowVue 10 is suitable for most alpine and remote installations. The SnowVue 10 also features Campbell Scientific’s total uptime diagnostic package to provide you with critical sensor performance measurements such as internal humidity, temperature, sensor level (tilt), measurement quality, and incoming voltage. An external air temperature sensor is required to correct for the changes in sound velocity due to changes in temperature.

This featured product was part of the Aconcagua expedition to install a weather station on South America’s tallest peak. Learn more about the expedition on our Extreme Application Series: Aconcagua page.

Key Advantages

High Sensitivity and Low Noise
For best-in-class performance

Technical Description

The SnowVue 10 uses a wide-band, ultrasonic transducer to create sound pulses that are reflected off the snow surface. By measuring the two-way travel time of the pulse, the distance to the snow surface can be precisely calculated using advanced spectrum analysis. Because the speed of sound through air varies with the air temperature, an accurate air temperature measurement is required to correct for this change.

Benefits

  • Snow-depth measurements with low noise and high precision
  • Low power usage for remote solar applications
  • Exceptional reliability with advanced diagnostics
  • SDI-12 v.1.4 output compatible with current Campbell Scientific data loggers

Measurement Range
0.4 to 10 m

(1.3 to 32.8 ft) distance from sensor

Snow Depth
0 to 9.6 m

(0 to 31.5 ft)

Accuracy
Accuracy specification is for still air with uniform temperature between the sensor and a flat, solid target. Air movement, temperature gradient along the sonic path, snow density, and differences between actual and measured temperature can affect the accuracy. An external temperature compensation is required.
