PROSA Professional-Sapflow-Evaluation Software - With the PROSA-App we have developed a tool which allows the comfortable evaluation and visualization of measured values from sap flow sensors, dendrometers etc.. Embedded in the user administration of our WEBvis solution, data can be selected from the WEBvis environment or external measured values can be uploaded. For the calculation of the sap flow density or the sap flow volume, the user only has to enter the cross-sectional area of the trunk through which the sap flow flows and decide on a method for determining the night maximum of the temperature difference of the sensors. Take a look for yourself and apply for a demo account via sapflow@upgmbh.com. The use of the PROSA app is billed as SaaS (software as a service).
