The SFM1 Sap Flow Meter is a self contained, standalone instrument for the measurement of sap flow or transpiration in plants.
The SFM1 is a complete package containing sap flow sensors, data logger, interface software and internal battery which can be charged with an external solar panel.
The instrument enables almond growers to reduce irrigation costs, increase whole farm productivity, and improve crop quality by providing real time, empirical data.
Almond sap flow and water potential data for a period of 30 days showing an increasing base line due to environmental conditions. Zero sap flow conditions were met only when irrigation is combined with a rainfall event (7 Feb 2017).
