摘要
介绍一种以89C58单片机为中央处理器的智能流量积算仪。它具有精度高、动态性能好,同时测量瞬时流量和累计流量两个参数,测量结果以LED显示,掉电数据不易失,并配有RS232串行口输出。
An intelligent flow totalizer based on 89C58 MCU is introduced. It offers high precision and good dynamic performance. The prompt and total flow can be measured and displayed through LED at the same time. The data do not disappear when power is off. It is also equipped with a RS232 output.
