This project aimed to design and build a cheaper device used to measure the water flow rate in trees by applying the heat pulse technique. The personal computer was used to process data, show and control the device which consisted of two probesets and a transfer signal unit. The experimental results on the average water flow rate of jackfruit and mango trees were consistent with the water requirement behavior of the trees.
