The SF-G sensor is the typical Granier sensor and consists of two needles

Advantages

  • Suitable for tree diameter >2 cm

  • Reusable sensor

Limits

  • Temperature difference between the needles is superimposed by natural vertical temperature gradients within the sap wood (up to + / -2.5 ° C). This occasionally leads to unpredictable errors of over 50% in sap flow calculations.

  • Sap flow at night cannot be measured. Due to unpredictable temperature overlays, night values are wrongly set to zero.

Available Models

  • SF-G 20/33, depth of installation 20-33 mm

  • SF-G 20/43, depth of installation 20-43 mm

  • SF-G 20/63, depth of installation 20-63 mm

Delivery by Standard Version

  • Sensor with 5 cable, weatherproof cap, Aluminium tubes

Options / Ordering Information

  • Cable extension (please specify in meters, but max. 20 m)

  • CCS power supply (one CCS is enough for up to 3 SF-G sensors)

  • Installation tools

  • Data Logger
