  • Page 10: Overview

    5. Overview The SnowVUE 10 measures the distance from the sensor to a target. It determines this distance by sending ultrasonic pulses (50 kHz) and listening for the returning echoes reflected from that target. The time from pulse transmission to echo return is the basis for obtaining the distance measurement.

  • Page 12 CAUTION: The SnowVUE 10 calculates distance readings using the speed of sound at 0 °C (331.4 m/s). If the temperature compensation formula is not applied or manually specified using the XWT! command, the distance values will not be accurate for temperatures other than 0 °C.

  • Page 13: Installation

    For the GRANITE-series, CR6, and CR1000X data loggers, triggering conflicts may occur when a companion terminal is used for a triggering instruction such as TimerInput(), PulseCount(), or WaitDigTrig(). For example, if the SnowVUE 10 is connected to C3 on a CR1000X, C4 cannot be used in the TimerInput(), PulseCount(), or WaitDigTrig() instructions.

  • Page 14: Programming

    7.2 Programming Short Cut is the best source for up-to-date programming code for Campbell Scientific data loggers. If your data acquisition requirements are simple, you can probably create and maintain a data logger program exclusively with Short Cut. If your data acquisition needs are more complex, the files that Short Cut creates are a great source for programming code to start a new program or add to an existing custom program.

  • Page 15: Beam Angle

    CAUTION: The SnowVUE 10 calculates distance readings using the speed of sound at 0 °C (331.4 m/s). If the temperature compensation formula is not applied or manually specified using the XWT! command, the distance values will not be accurate for temperatures other than 0 °C.

  • Page 16: Mounting Height

    7.4 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...

    The SnowVUE 10 may reject readings from a moving target. If the SnowVUE 10 rejects a reading or detects no target, 0 will be output for the distance to target and for the quality number.

    8.2 Pitch, roll, and tilt axis The SnowVUE 10 reports pitch and roll to ensure that the sensor is mounted to be perpendicular to the intended target surface. The front of the sensor is the face with the vent on it (opposite the...

    The different commands are entered as options in the SDI-12 recorder instruction. If the SnowVUE 10 is unable to detect a proper echo for a measurement, the sensor will return a 0 for the distance-to-target value. Table 8-2: SDI-12 commands Max. sensor...

  • Page 24: Updating The Operation System (Os)

    CR1000X: OS 5.0 or newer CR300 series: OS 10.05 or newer The XLOADOS! OS update process requires access to the data logger terminal. Campbell Scientific Device Configuration Utility is recommended. Although this update may be performed remotely, if the sensor is not communicating with the data logger, it must first be power cycled to regain communication and accept the new OS.
  • Page 25 1. Download the update file from the Campbell Scientific website and run the self-extracting executable. The extraction takes only a moment, and a dialog box will indicate that the OS file has been saved to the computer. Take note of the directory where the SnowVUE 10 OS is saved on the computer: C:\Campbellsci\Lib\OperatingSystems.
