ECA-YL04 Stem Flow Meter Introduction: Determine the water consumption (transpiration) of trees by directly measuring the water flow rate of their stems; Based on the rate of upward transfer of heat pulses added to the stem flow and the degree of heat exchange with the surrounding water flow, the stem flow rate of the stem can be calculated using the theory of heat transfer and heat balance through certain mathematical calculations. Features: 1. Measurement method based on thermal equilibrium method; 2. The sensor adopts a wrapped installation method, which does not cause damage to the plant itself; 3. Built in heat and temperature sensors; 4. Rechargeable lithium battery power supply, which can be used for field measurement environments; 5. The collection time interval can be set to meet different measurement needs; 6. There are two modes of automatic measurement and manual measurement 7. Users can set their own heating time and plant radius; 8. Power consumption based on stem flow size, maximum 0.15A 9. High measurement accuracy and fast corresponding speed 10. Can measure herbaceous and woody plants, suitable for a large space 11. Screw structure design, easy to overcome the influence of human operation on measurement results 12. Low price, suitable for China's national conditions Technical parameters: Measurement range: 0-500N Measurement accuracy: 0.1% Resolution: 0.1N: Stem diameter range: 5-50mm (standard configuration with 1 sensor, customized according to user requirements) Heating technology: thin film heating element Stem length required for installing probe: 10-15cm Heating power: variable, up to 2W Measurement interval: 1-99 minutes Power supply: rechargeable lithium battery Working temperature: -10 to 40 degrees Celsius (Deg. C) Storage space: 4G Instrument host size: 155mm * 90mm * 60mm Memory: SD card 2GB
