Our systems are based on heat balance method with clear theoretical background. The sap flow sensor output is in terms of [kg hr-1] per plant. At present we offer two different systems; for small diameters (8 to 20 mm) and for large trees with stem diameter over 12 cm. Both systems use variable power and constant dT.
Sap Flow small stems
- THB method with variable power (dT 2, 4 or 8 K)
- Two sensor sizes:

Sap Flow large trees
- For stems from 12 cm DBH
- THB method with variable power (dT 1, 2 or 3 K)
- Output in [kg hr-1] per tree independent on radial sap flow profile
- Input for stem increment sensor
- Built-in datalogger
