System for measuring heat flow
First Claim
1. A system for determining and measuring the heat flow rate between a first and a second medium, said system comprising:
- at least two sensor units having signal outputs disposed in a spaced-apart relationship, each of said units including a transducer having apertures allowing fluid to pass therethrough;
the transducer of a first sensor unit being affixed, at least indirectly, to a first surface on said first medium, the heat flow of which is to be determined, a second surface of said first transducer of the first sensor unit being exposed to said second medium;
a first surface of the transducer of the second sensor unit being affixed to a calibration plate or a known coefficient of thermal conductivity, said calibration plate being located between said second sensor unit and said first medium and exposed to said first medium, the heat flow rate of which is to be determined, the second surface of said transducer of the second sensor unit being exposed to said second medium;
the signal outputs of said transducers being connectable to a processing unit for determining and measuring changes in the heat flow between said first and said second mediums.

Abstract
The invention provides a system for determining the heat flow rate between a first and a second medium, the system including at least two sensor units having signal outputs disposed in a spaced-apart relationship, each of the units including a transducer having apertures allowing fluid to pass therethrough; the transducer of a first sensor unit is affixable to a first surface on the first medium, the heat flow of which is to be determined and a second surface of the first transducer is exposed to the second medium; a first surface of the transducer of a second sensor unit is affixable to a calibration plate, the calibration plate is affixable to the first medium, the heat flow of which is to be determined and the second surface of the transducer is exposed to the second medium; the signal outputs of the transducers are connectable to a processing unit for determining changes in the heat flow between the first and the second sensor units.
