Abstract
A calorimetric probe for measuring heat produced in a fluid consists of a tube through which the measured fluid flows and having two thermoelements at intervals spaced along the tube, each being connected between the tube and a surrounding element having good heat transmitting qualities, the surrounding element itself being separated from the first tube by a column of air so that a comparison of the readings of the two thermoelements provides a measure of heat developed in the liquid while passing between the two thermoelements.
Claims4
Calorimetric probe for measuring exothermic reactions in a liquid, comprising a protective cover defining a hollow vessel to be immersed in heat exchanging relationship in a body of said liquid, an elongated tube in communication with said body of liquid and defining a flow path for said liquid, at least a portion of the length of said tube being contained within said protective cover in heat isolating relationship thereto, a pair of thermoelements and means thermally coupling each of said thermoelements between said protective cover and said elongated tube at respective locations spaced along the length of said heat isolated portion, each of said thermoelements being capable of measuring the temperature difference between the protective cover and the elongated tube at said respective spaced locations, whereby the exothermic heat produced during a flow of said liquid between said spaced locations can be measured.
