Sap Flow Systems


Warning: Due to system migration to more powerful server resources there may outages of the website and its data from Monday 9th September 2019 to Friday 20th September.


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:
    • 6 to 12 mm
    • 10 to 20 mm

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
