Sap Flow Tool v1.2
"Analysing
sap flow data
never went
so fast..."
"It is a very nice, fast and convenient way of processing the sap-flow data. It was great to have the data processed right away on the field, even sap-flow rates and all. I must say I feel very satisfied with it as normally the post processing of sap-flow data is time consuming."

Visually fix bad data
Visually inspect raw sensor signals and quickly fix bad or missing data
Sap Flow Tool imports raw sensor data from .csv text files. The data can then be analysed in detail.
If bad data is present: simply mark the affected region and apply one of several "filters":
K-values
Automatic calculation of HFD K-values
In order to calculate sap flow rates from HFD sensor data, K-values need to be obtained for each thermistor position.
Sap Flow Tool automatically calculates K-values using an intelligent adaptive regression algorithm that will automatically determine the optimal portion of the data needed for the regression.
Sap Velocities (HRM) &
Sap Flux Densities (HFD)
Visualize sap velocities and sap flux densities in 2D and 3D
Sap velocities (HRM)(cm/h) and sap flux densities (HFD)(cm3/cm2/h) are calculated for each thermistor position in the sensor.
Visualisation is done in 2D (as a funtion of time) (upper graph) and in 3D (as a function of time and depth) (lower graph).
All graphs are interactive and can be zoomed, scaled and rotated (3D only). A top-view surface plot is also available.
Radial profile
Interactive radial sap velocity (HRM) and sap flux density (HFD) profile
2D sap velocities (HRM) or sap flux densities (HFD) are displayed as a function of time (upper graph) and depth (lower graph). The latter is called the sap velocity (HRM) or sap flux density (HFD) radial profile.
The radial profile at each time instance can be visualised by moving the red marker line across the upper graph. This causes the corresponding radial profile to be shown in the lower graph. Sap wood depth and xylem radius are indicated by red lines on the radial profile graph.
Flow rates
Visualize sap flow rates in 2D and 3D
Sap flow rates (cm3/h) are calculated for the sapwood rings around each thermistor position of the sensor. Besides the total sap flow rate, cumulated flows over time and daily flows are also calculated.
Visualisation is done in 2D (as a funtion of time) (upper graph) and in 3D (as a function of time and depth) (lower graph).
All graphs are interactive and can be zoomed, scaled and rotated (3D only). A top-view surface plot is also available.
