DynaTree setup  B
 
x1    Portable pneumatic  pole   (1 Person use) 
For the anemometer,no special assembly of the pole itself is needed. Only the holding ropes which should be fixed correctly. The packed pole is about only 2 m long but it can be erected to 10 m height. Both the extending and the collapsing of the tower can be done alone.
 
Mechanical anemometer 
 
x1 Anemometer; Ball type (Mechanical) , an instrument for measuring wind velocity at or near the tree to be evaluated. The closer to the better, but, depending on wind velocity DynaRoot may provide reliable data even with measurements taken several kilometers /miles away. The anemometer provides wind velocity data of sufficient frequency.  Ideally the anemometer should be clear of buildings or other objects that may
obstruct the wind, at a height of at least 10 m.
Ball type anemometer
Sampling rate: 1 Hz
Measurement range: 0-150 km/h
Accuracy: 0.2 km/h
Integrated GPS
Data storage capacity: 8 GB (SD card)
Best location: open field, 10 m height, undisturbed by buildings or other large objects
Completely weather proof
 
 
 
x3 Inclinometer; which is fixed to the buttress of the test tree and measures the inclination of the trunk in two different directions to provide very accurate record of the trees movement in both the X & Y axis.  This device provides an accurate record of the trees inclination at sufficient frequency to identify excessive or sudden movement.
Measurement range ± 2 degrees
Resolution: 0.001° degree
Temperature compensated
Sampling rate: 10 Hz
Integrated GPS
Data storage capacity: 8 GB (SD card)
Mounted by a single screw
Operating voltage and current: 12V, 20 mA
Completely weather proof, IP65
 
1  Elastometer with sensors - An instrument attached to the trunk for measuring the micro elongation of the trunk.
 
3. Evaluation software
The data, recorded by the Anemometer & Inclinometer on to memory cards over a period of several hours are combined within the evaluation software, thanks to a GPS time signature. The software breaks the data down into shorter intervals, and calculates the statistical parameters for each interval
that are used for the tree stability evaluation.
Simple yet efficient software for determining the safety factor
Automatic merging of wind velocity and inclination data
Diagram, critical wind pressure, correlation coefficient and safety factor calculation
Runs under MS windows.
