- Plant Stem Flow Tester Product introduction:
The plant stem flow measuring meter uses the heat dissipation probe method to measure the instantaneous stem flow density of tree trunks, which can continuously observe the sap flow of trees for a long time. This is beneficial for studying the water exchange law between trees and the atmosphere, and using it as an observation method to monitor the impact of forest ecosystems on environmental changes for a long time. It has important theoretical guidance and practical value for afforestation, forest management, and forestry management.
Plant Stem Flow Tester Principle:
The plant stem flow measuring instrument adopts a new method for measuring Sap Flow invented by French scholar Granier after the 1980s, namely the heat dissipation probe method (constant heat flux sensor method). The data collection of this method has the characteristics of accuracy and stability, and can continuously read data without interruption, so the data is systematic. The measurement system consists of a pair of 30mm long heat dissipation probes. During installation, the probes are inserted into the edge wood of the tree at a distance of 10cm-15cm. The upper probe is wrapped with a resistance wire for direct current heating, while the lower probe is not heated and maintains the same temperature as the surrounding edge wood tissue. The temperature difference between the two probes reflects the liquid flow density of the tree.
