  • Procedure for measuring thermal energy transported by fluid flow
    Patent number: 4440507
    Abstract: A method is provided for measuring thermal power transferred to or from a flowing fluid, independent of the density and specific heat of the fluid. The method may also measure the thermal power transferred to or from the fluid independent of the flow rate of the fluid itself too. This is accomplished by providing a bypass in the fluid stream, determining thermal power transferred to or from the fluid flowing in this bypass line, and then relating the thermal power transferred in the bypass line to the thermal power of the principal fluid stream itself, by calculating temperatures at various points along the principal fluid stream and along the bypass line.
