| 摘要 |
The invention provides a new system for measuring the heat flow rate between a first and a second medium, the system includes at least two sensor units with signal outputs disposed in a spaced-apart relationship, each of said units including a transducer with apertures allowing fluid to pass through; the transducers are affixed to a first surface on the first medium directly or at least indirectly, and a second surface is exposed to the second medium; thus the said system includes at least two different calibration plates with known coefficient of thermal conductivity and said calibration plates inserted into a measuring line (scheme) of both the sensor units and are affixed behind or in front of the sensor units; the signal outputs of the said transducers arrive to a processing unit for determination and measurement of changes in the heat flow between the said first and the said second sensor units. |
