摘　　要：热量表是计量热流回路所释放热量的智能仪器。它主要由流量传感器、配对温度传感器、主控MCU和液晶显示等部分组成。其中流量计量的准确程序直接决定了热量表的精度等级。论述了以TIMSP430F135作为主控MCU的热量表的工作原理,讨论了该叶轮式无磁热量表流量测量的动态校准原理,并给出软硬件设计及分析。Heat meter is a kind of intelligent instrument that measures quantity of released heat from a thermal current loop,which is mainly consisted of a flow meter,a pair of partner temperature sensors,a controlling MCU,and a LCD.The precision level of the heat meter is directly decided by measurement accuracy of heat flux.Introduces a calibration method for the heat meter with TI MSP430F135 as controlling MCU.Dynamic calibration for flux measurement in a impeller mode and non-magnetic heat meter was discussed in detail,and software and hardware design and analysis are recommended.
