Plant Stem Flow Meter Overview
Plant Stem Flow Meter is used in agriculture and plant physiology to measure the flow of water through plant stems, serving to quantify transpiration and evapotranspiration.The thermal dissipation-based Plant Stem Flow Meter is designed according to the Granier sap flow measurement principle. It utilizes a two-probe configuration, in which the upper probe contains a heating element that provides constant-power heating. Thermocouples are used to measure the temperature difference between the upper and lower probes. Based on these measurements, the sap flow rate within a plant stem can be calculated using the thermal dissipation principle and empirical coefficients, providing insight into the plant's transpiration and water consumption.
