CLAIMS

What is claimed is:

1. A sap flow measurement device comprising:

an elongate circuit board having a proximal end and a distal end;

one or more downstream temperature sensors disposed along a length of the circuit board;

one or more upstream temperature sensors disposed along the length of the circuit board parallel to the one or more downstream temperature sensors; and

one or more heating elements disposed along the length of the circuit board parallel to and in between the downstream and upstream temperature sensors.

2. The sap flow measurement device of claim 1, further comprising microcontroller removably attached to the proximal end of the circuit board and configured for logging data from the one or more upstream and downstream temperature sensors and controlling the heating elements.

3. The sap flow measurement device of claim 1, wherein a plurality of heating elements are disposed along a length of the circuit board, and wherein adjacent heating elements are spaced apart at intervals along the circuit board.

4. The sap flow measurement device of claim 1, wherein a plurality of downstream temperature sensors and a plurality of upstream temperature sensors are disposed along a length of the circuit board, wherein adjacent downstream temperature sensors are spaced apart at a first interval along the circuit board, and wherein adjacent upstream temperature sensors are spaced apart at the first interval along the circuit board.

5. The sap flow measurement device of claim 4, wherein each of the one or more heating elements are disposed in alignment with downstream and upstream temperature sensors.

6. The sap flow measurement device of claim 5, wherein the downstream and upstream temperature sensors are in alignment with alternating heating elements.

7. The sap flow measurement device of claim 1, wherein the downstream temperature sensors are spaced apart from the heating elements at approximately the same distance as the spacing between the upstream temperature sensors and the heating elements

8. The sap flow measurement device of claim 1, wherein the upstream temperature sensors are disposed closer to the heating elements than the downstream temperature sensors are disposed from the heating elements.

9. The sap flow measurement device of claim 1, further comprising a pressure sensor disposed along the length of the circuit board.

10. The sap flow measurement device of claim 9, wherein the pressure sensor is disposed on an opposite side of the circuit board from the heating elements and the temperature sensors.
