ABSTRACT:
The disclosed apparatus measures the temperature at the inlet and at the outlet of equipment such as a solar heater, and meters the flow of fluid through the equipment. An electrical signal representing the difference between the inlet temperature and the outlet temperature is multiplied by the output signal of the fluid metering device to register the amount of heat exchanged during a given time interval. The volumetric changes of fluid density at the flow meter and the error in performance of the flow meter that may occur due to changes in fluid temperature passing through the flow meter are automatically taken into account in the computation.
