The Sap Flow Meter is a self-contained, stand-alone instrument for measuring sap flow or transpiration in plants. Utilising the Heat Ratio Method (HRM) principle, the Sap Flow Meter can measure high, low and reverse flow rates in both small woody stems and roots and large crops including tea, rubber and oil palm. As the only instrument that can measure zero flow and reverse sap flow rates, the Sap Flow Meter is the most powerful and flexible instrument for the direct measurement of plant water use.

Following the donation, Dr. Mujith Ariyarathne, Head of the Crop Science Department at the University of Peradeniya, conducted a full demonstration of the Sap Flow Meter unit in the presence of university officials, lecturers, students and the representatives of Watawala Plantations.
