SF sap flow sensor

Product of
Ecomatik
This sensor for the continuous measurement of the water absorption of trees operates according to the Granier principle. This measures the temperature difference between two needles that are arranged on top of each other, whereby the top needle is heated by a constant energy supply. The temperature difference can be converted to the water flow using an empirical formula.Two models are available depending on the degree of accuracy required:
- SF-G, classic Granier sensor with 2 needles
- SF-L, improved Granier sensor with 4 needles and a considerably greater degree of accuracy
The needles are available in 3 different lengths so they can be ideally adapted to the tree size. The energy supply for the upper needle is provided by a CCS power supply for up to 3 sensors. An external data logger is required to record the data. The sensors are supplied with 5 m of cable, weather protection cap and aluminium tubes. The cable can be extended to up to 20 m on request.
