SodarF3D uses proprietary technology housed in a robust and portable unit. What makes the SodarF3D unique includes:
SodarF3D is the best priced Sodar on the market. The flexibility of the SodarF3D and its optional equipment adds significant value to your development, operational performance or other applications.
ALL SodarF3D packages include these base functionalities
Suitable for mild winters where average temperatures are below zero, but snow is uncommon and good solar energy input is available.
Our standard hardware can be expanded to include additional solar and weather sensors.
Validation by DNV-GL, Parsons Brinckerhoff, Entura.
DNV GL accepts SodarF3D data in bankable wind energy assessments on benign sites.
Generally does not require a planning permit to install, enabling more data captured and faster. The easily portable unit allows monitoring at a number of locations around your site to significantly reduce uncertainty.
Performs well in complex and simple terrain and housed in a robust, portable unit.
More flexible than a Met Mast, lower cost than a Lidar. Significantly cheaper than a Hub Height Mast – in some cases half the cost.
FlightDECK™ collects, stores and verifies your data for secure, fast download for self managed equipment locations and configurations.
Incorporates fully traceable data architecture, sending all raw sound spectrum data to the Fulcrum3D servers for off-site processing while saved in secure back-up storage.
Resource assessment – prospecting for sites and proving wind resource;
Power curve verification – confirming turbine performance in a variety of wind conditions;
Performance monitoring – maximise the long term performance of your asset;
Wind forecasting – for energy sales or optimising network integration.
The SodarF3D is unique in its design.
A standard Sodar works by sending out a sound pulse (beep) and listening to the returned sound signal as it’s scattered back towards the Sodar by atmospheric turbulence. You can listen to the sound pulse here. The principle, is similar to Radar.
The three sound beams of the SodarF3D allow a three dimensional wind vector to be measured. After the pulse is transmitted, the SodarF3D begins recording the returned sound signal and various filtering techniques are used to eliminate false data, background noise, errors introduced from rainfall and other factors.
The SodarF3D measures wind speed, direction and inflow angle in 10m height intervals from 40m to 200m above ground level, which aligns with the height of modern wind turbines. For each height range, data quality and other measurement statistics are calculated every 10 minutes.
The wind speed, direction, inflow angle, and height range are then calculated based on:
This wind vector is then translated into wind speed, direction, and inflow angle in each height bin. More complex analysis allows the wind speed standard deviation and turbulence index to be calculated. The SodarF3D transmits a sound pulse approximately every 1.5 seconds, giving a large number of samples which are then analysed to generate 10 minute statistics.
The SodarF3D is a portable unit, mounted on a standard box trailer, and powered by its own low-maintenance solar battery system. It is supplied with on-board remote telemetry, for a set-and-forget solution which reliably provides accurate data to your desktop.
