DynaRoot System - for root stability

DynaRoot system for root stability evaluation composed of  3 main components: 

 

 

1. Anemometer; an instrument for measuring wind velocity at or near the tree to be evaluated. The closer 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.

  • Dual axis ultrasonic wind velocity meter

  • 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

 

  

2. 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

 

 

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.

 

 

Optional support pole for Anemometer required  which can be supplied  upon request.
