Using an Ultrasonic RangeFinder for Snow Level Measurement

 

Ultrasonic RangeFinder for Snow Level Measurement When winter arrives at our production facilities in Minnesota, we see a lot of snow. An ultrasonic rangefinder for snow detection is a great way to measure just how much snow Old Man Winter brings. Ultrasonic sensors traditionally struggle to detect snow because it acts like a sound dampener. You can gain further understanding of how snow dampens sounds at this link on Ultrasonic Rangefinder Target Acoustics.

At MaxBotix Inc., we produce a range of weather resistant and snow ultrasonic sensors that help you successfully overcome the difficulties of detecting soft targets like snow. The reliability and accuracy of a measurement are two main concerns when detecting snow. A true and accurate reading depends upon a range of factors surrounding both the snow and the ultrasonic sensor.

This makes it important to find a solution that was designed with snow in mind. We maintain successful and accurate readings by compensating our ultrasonic rangefinders for temperature, voltage, and target size while maintaining proper sensitivity to detect the density of fresh snow. Learn more about our Snow Level Measurement Ultrasonic Rangefinders Accuracy.

Once you have your hands on a proper ultrasonic range finder, a final yet extremely important step for snow level measurement is the mounting of the ultrasonic sensor. The height and distance of the ultrasonic sensor from surrounding obstacles is a key point in mounting the ultrasonic rangefinder. This includes where and how you measure the temperature for proper range compensation. You can read the details and instructions for proper mounting in our article Mounting an Ultrasonic Range finder for Snow Level Measurement.

The MB7334 and the MB7354 will produce great results for most snow depth measurements. The accuracy was measured over 5 days on three million continuous readings with ultrasonic snow sensor data presented here.

The graph below shows the outputs from our three of our ultrasonic sensors. These sensors filter the outputs and the graph shows what happens when a target is moved 10cmm over a 90 second time period. Snow doesn't come down that fast, so the sensors don't need to respond that quickly so MaxBotix designed ultrasonic sensors to specifically make snow sensing much more reliable.
