Quotation for Plant Stem Flow Measurement System

SF-GStem flow (liquid flow) measurement systemDirectly measuring plant stem flow to determine plant water consumption (transpiration). If other sensors are added, plant stem flow can be measured under environmental factors such as air temperature, humidity, PAR, soil temperature, humidity, etc.

Principle:The SF-G stem flow sensor is a probe based instrument invented by French inventor GRANIER for measuring daytime stem flow. During work, two probes are inserted into different parts of the tree trunk. The upper probe is heated by a constant flow, creating a temperature difference between the two probes. When the stem flow rises, it takes away heat, and the temperature difference between the two probes decreases. There is a functional relationship between the temperature difference and the stem flow. Calculate stem flow by measuring temperature difference. Different stem flows generate different temperature differences, and sensors sense the small voltage generated thereby, providing data for stem flow calculation To calculate daytime stem flow, a stem flow value of zero must be set.
