Sapflow Sensors
Heat Ratio Method (HRM) HRM Installation Kit	The Heat Ratio Method (HRM) is a modification of the Compensation Heat Pulse Method (CHPM). The HRM improves on the CHPM by allowing very slow flow rates and even reverse sap flow to be measured. This allows water flows to be monitored in stems and roots of a wide range of different species, sizes and environmental conditions, including drought.
Heat Field Deformation Sapflow (HFD) Download PDF slides of HFD Installation Instructions	The Heat Field Deformation (HFD) technique is ideally suited to sapflow research projects that require the measurement of extended radial sapflow profiles to accurately map hydraulic architecture of trees. Similar to the HRM sap flow sensor the HFD sensor can measure high sapflow rates as well as low to zero and reverse sapflow. Hence as both sensors can measure in the same range the HFD sensor provides an extension of the HRM method making both sensors highly complimentary to each other in most sapflow measurement applications.

Energy or Heat Balance (Dynagage)	The stem heat balance (SHB) method was originally proposed by Sakuratani (1981) to measure the mass flux rate or sapflow in small stemmed herbaceous plants. The SHB method is based on the energy balance of a stem segment to which regulated heat energy is constantly supplied by an external annular heater.
Thermal Dissipation (TDP)	The Thermal Dissipation Probe (TDP) directly measures sap velocity which can be converted to volumetric flow rate given an accurate measurement of sapwood area for the tree. TDP is an uncomplicated and inexpensive method ideally suited to whole plant transpiration measurements on large diameter trees.
