WebHFP01 heat flux plate is the de-facto standard for heat flux measurement on walls. In high accuracy flux measurement a typical station is equipped with two or more sensors for good spatial averaging. Our TRSYS01 is a measuring system for analysis of the thermal resistance and the thermal transmittance of building elements by in-situ measurement. WebHeat transfer (q) is the movement of thermal energy as a function of time. Typical units are watts, the same as power, which is the movement of mechanical energy as a function time. Heat flux is heat transfer per surface area (q"), with units of watts per square meter. This is analogous to a power density.
