The Dynamax Dynagage sap flow sensor consists of a flexible heater, a thermopile to measure radial heat loss, and differential thermocouple pairs to measure the axial temperature differences qu-qd.
All of these sensors and heater are mounted on a cork substrate and housed inside a white, reflective foam, thermal insulating collar. Once the sensor is installed on the stem surface, both the sensor and the stem sections above and below the sensor are completely covered by a heat insulator to minimise thermal perturbations caused by the ambient environment. Power is supplied continuously to the heater from a regulated DC power source.
