Mounting height

Mount the SnowVue 10 so that the face of the transducer is at least 70 cm (27.5 in) away from the target. However, mounting the sensor too far from the target can increase the absolute error. For example, if your sensor is measuring snow depth in an area that will likely not exceed 1.25 m (4.1 ft), then a good height to mount the sensor could be 2.0 to 2.2 m (6.56 to 7.22 ft). Mounting the sensor at a 4 m (13.1 ft) height could result in larger snow depth errors.

Reference point

The front grill on the ultrasonic transducer is used as the reference for distance values. Because of the difficulty of measuring from the grill itself, most users measure the distance from the target to the outer edge of the plastic transducer housing (Depth of space from edge of transducer housing to grill) and then add 8 mm (0.3 in) to the measured distance.
