Abstract: PURPOSE:To enable direct measurement of changes with time at a high accuracy in mixing, dilution and reaction by employing a series/linear detector or detectors as calorific value detectors to insert a heat insulating plate in the course thereof. CONSTITUTION:A polyethylene tube having a manganin wire 4 wound in a coil as electric resistance wire on detectors (e.g. thermomodule) 1 arranged in a series and linearly is used for a sample path tube 3 and arranged zigzag. The detectors are divided by three, for instance, and are isolated from one another with a poorly heat conducting teflon plate 5 together with metallic heat sinks 2 supporting them. The detectors 1 are screwed down 6 on a semi- cylindrical thermostat heat sink 7 and a thermostat 7 is laid thereon utilizing a screw hole 8 to form a detection unit. Two kinds of fluids to be measured enter at an inlet 9 of the tube 3, mixed to react and then, discharged 10. Thus, groups of three detectors work independently as calorific value detection unit thereby enabling a wide ranging measurement of changes with time with a varying of a flow velocity.
