External sapflow sensors are a useful tool in plant ecology and physiology for monitoring water movement within small stems or other small plant organs. These gauges make use of heat as a tracer of water movement through the stem and can be applied in both a laboratory and a field setting to generate data of relatively high temporal resolution. Typical outputs of these data include monitoring plant water use on a diurnal time scale or over a season (, in response to increasing water deficit during drought) to gain insight into plant physiological strategies. This protocol describes how to construct the gauges, how best to install them and some expected data outputs.
外部液流传感器是植物生态学和生理学中用于监测小茎或其他小植物器官内水分运动的有用工具。这些测量仪利用热量作为水分通过茎部运动的示踪剂，可应用于实验室和野外环境，以生成具有相对高时间分辨率的数据。这些数据的典型输出包括在昼夜时间尺度或一个季节内监测植物的水分利用情况（例如，响应干旱期间水分亏缺的增加），以深入了解植物的生理策略。本方案描述了如何构建测量仪、如何最佳安装它们以及一些预期的数据输出。
