Sonic Anemometer/Thermometer is a stable, low powered anemometer, capable of running unattended for extended periods of time. Use with a Sensor Transmitter or an EnviroMonitor Node, or as a replacement anemometer for wireless and. Sonic temperature is also available in the output data.Ī range of sensor variants is available to cover a wide range of applications. The Sonic Anemometer/Thermometer is connected to a computer running a terminal emulation program, or can be connected directly to a dumb terminal. Sonic AnemometerMeasure wind with no moving parts. The lack of mechanical inertia also allows measurements to be taken at high frequency allowing precise time dependent measurement. A conservative range of uncertainty for a full scale industrial application. The local instrument disruption is studied under a typical level of turbulence. Correction of the signal, restrictions and guidelines for a full scale methodology. This method allows accurate measurement even at low wind speeds as there is no mechanical inertia to overcome. The application of a HS50 sonic anemometer to industrial swirl towers is explored. Ultrasonic anemometers measure wind speed by detecting the difference in time taken for an ultrasonic pulse to travel in each direction between pairs of transducers caused by movement of the air. The ATMOS 22 is not only far more affordable than other sonic anemometers but also uses 100 to 1,000 times less power. Users include wind energy site surveyors. ![]() The sensors can provide a very wide range of output parameters allowing use in the study of turbulence as well as more basic wind speed and direction measurement. WindMaster 3-axis ultrasonic anemometers are used to gather high value information by a range of customers. The electronics of the ultrasonic anemometer is based on the latest DSP (digital signal processor) technology. The sensor arms are automatically heated if necessary ensuring continued operation in snow and during icing events. With no moving parts the anemometer is free from wear and maintenance and needs no calibration. ![]() The 3D Ultrasonic Anemometer measures the horizontal and vertical components of the wind speed and wind direction.
