Abstract: MSP430 ultra-low power 16-bit single-chip puter is used as the core of heat meter. The
low-power, non-ic measurement of flow is realized using SCANIF module bining with LC concussion
circuit. A built-parator and Σ− technology are used to form a high accurate 16-bit A/D convertor, -
bining with PT1000 platinum resistance the temperature is measured. The heat is obtained after the integral of flow
temperature information. The test shows that the error of this measurement method is extreme low and meets the re-
quirements of heat meter in the National Standard. Combining with ZigBee mo
