Title (EN) A METHOD AND A METER FOR MEASURING QUANTITIES OF HEAT
(FR) METHODE ET APPAREIL DE MESURE DE QUANTITES DE CHALEUR
Abstract: front page image
(EN)A method and a meter for measuring the quantity of heat abstracted from a circulating flow of liquid by a consumption unit based upon the indirect measurement of the volume flow rate of the liquid, while maintaining a sub heat flow (Q shunt) from or to the main heat flow transported by the flow of liquid and measuring the temperature at some points by means of temperature sensors (4), whereby the volume flow rate of the flow of liquid is determined on the basis of the flow rate dependent heat transfer in the boundary layer (7) of the flow of liquid at the location, where the sub heat flow (Q shunt) leaves or enters, by determining the temperature differential ((Alpha)Ti,b) across the boundary layer, and the sub heat flow (Q shunt) passing through said boundary layer (7), while at least one absolute temperature of the flow of liquid is measured for correcting the temperature dependency of the material constants of the liquid involved in said determination of the volume flow rate.
(FR)Methode et appareil de mesure de quantites de chaleur extraites d"un ecoulement de liquide de circulation par une unite de consommation qui se basent sur la mesure indirecte du debit du volume de liquide, tout en maintenant un sous-ecoulement de chaleur (shunt Q) provenant de ou allant vers l"ecoulement principal de chaleur transporte par l"ecoulement de liquide, et sur la mesure de la temperature en certains points au moyen de capteurs de temperature (4), de maniere a determiner le debit de volume de l"ecoulement du liquide sur la base du transfert de chaleur en fonction du debit dans la couche limite (7) de l"ecoulement de liquide au point ou le sous-ecoulement de chaleur (shunt Q) sort ou entre, par determination de la temperature differentielle ((Alpha)Ti, b) de part et d"autre de la couche limite, et le sous-ecoulement de chaleur (shunt Q) passant au travers de ladite couche limite (7), au moins une temperature absolue de l"ecoulement de liquide etant mesuree pour corriger la dependance avec la temperature des constantes du liquide impliquees dans ladite determination du debit de volume.
