The Dynagage Sap Flow Sensors are used for measuring the sap flow, and thus the water consumption of plants. These energy balance sensors measure the amount of heat carried by the sap which is converted into real-time sap flow in grams or kilograms per hour.

The sensors are non-intrusive and not harmful since the plants are heated up 1º C to 5º C typically. The principles of heat balance sensors are scientifically proven and references  exist for most major crops and many tree species. Unlike other methods, Dynagages require no calibration since sap flux is directly determined by the energy balance and rates of heat convection by the sap flow.

Dynamax introduced the first sap flow sensor prototypes in 1988 and today offers a full range of sensors from 2 mm up to 150 mm.
