The SF-G (SF-20) SAP Flow Sensor is the typical Granier sensor and consists of two needles.
Advantages:
■ Suitable for tree diameter >2 cm (see available models)
■ Reusable sensor
Disadvantages:
■ Temperature difference between the needles are superimposed by the vertical variation of Stem temperature (up to + / -2.5 ° C). This leads to unpredictable errors of over 100%.
■ Sap flow at night can not be measured. Due to the temperature overlays the night values are incorrectly set to zero.
Compatible wih Data Loggers:
UX120-006M for up to 4 channels.
H22-001 .
Options / Ordering Information:
■ Cable extension for SF-G (please specify in meters, but max. 20 m)
■ CCS Constant Current Power Supply (one CCS is enough for up to 3 SF-G sensors). Requires constant current source (CCS) for 3 sap flow sensors (SF-L or SF-G or mixed).
■ Installation tools
■ Data Logger
