ABSTRACT:
A method and apparatus for measuring the rate of flow and the totalized quantity of thermal energy flowing through a conduit. A small proportion of the thermal energy flowing through a conduit is by-passed to a heat exchanger, which is otherwise isolated from the thermal energy in the conduit, and shunted to a heat sink maintained at a reference temperature. The temperature differential along the heat shunt is measured as an indication of the total heat flow through the conduit.
