Sap Flow Sensor type SF-G

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
