基于游标时间测量方法的超声波热量表系统

Ultrasonic Heat Meter System Base on Nonius Time-Measuring Method

为了提高超声波热量表的测量精度及降低功率损耗,设计了一种超声波热量表。在超声波热量表的原理上,选用时间游标测量法、四线制引线方式和C8051F320单片机。实验结果表明,该设计出的超声波热量表功耗低、精度高,可持续工作7年。

A ultrasonic heat meter was developed to improve measurement accuracy and reduce power loss. The principle of ultrasonic heat meter uses nonius time measuring method, four wire lead way and C8051 F320 SCM. The result shows that ultrasonic heat meter can work seven years with low power consumption and high measurement accuracy.
