Abstract: | Designed a kind of heat meter of small pipe with the super low power MSP430F4371 as the main controller. The measurement of temperature was realized by time interval measurement chip TDC-GP21 with high precision and the measurement of flow was also realized by the chip with ultrasonic; through MBUS and infrared with data-encrypting, this paper realized remote meter reading and live meter reading with hand instruments; it is convenient for residents to check with Chinese character display. Tests on the calibration table show that the designed products with errors under 1% are low power and stable. |
