Abstract

A technique for use in measuring the amount of heat entering (or being withdrawn from) a continuous fluid stream at a specific location along its path is disclosed herein. This technique utilizes a constant ratio fluid flow divider, e.g., a fluidic bridge, for diverting a portion of the fluid stream along a bypass route. Heat is applied to the diverted stream along its bypass route and, at the same time, the difference in temperature between the diverted stream and the mainstream is detected at predetermined points. From this difference, the amount of heat applied to the diverted stream is controlled so as to substantially eliminate any temperature differential between these points. The amount of heat to accomplish this is proportional by a fixed amount to the heat entering (or leaving) the main stream at the heating (cooling) process to be measured.
