| description | PCT No. PCT/NL80/00008 Sec. 371 Date Nov. 17, 1980 Sec. 102(e) Date Nov. 17, 1980 PCT Filed Mar. 21, 1980 PCT Pub. No. WO80/02072 PCT Pub. Date Oct. 2, 1980.A method and a meter for measuring the quantity of heat abstracted from a circulating flow of liquid by a consumption unit. Indirect measurement of the volume flow rate of the liquid is made, 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). 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 ( DELTA Ti,b) across the boundary layer, and the sub heat flow (Q shunt) passing through said boundary layer (7). 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. |
