廉价电远传式微小气体流量传感器的研究

Study on a Low- cost Long-distance Electric-transfer Transducer for Tiny Gas Flow Measurement

介绍了利用普通玻璃浮子流量计配合光电传感器 ,加以单片计算机控制构成的电远传式微小气体流量传感器的设计方法。

This paper introduces one long- distance electric- transfer transducer used in tiny gas flow measure- ment. The transducer combines ordinary glass rota- meter and photoelectric sensor with control circuit super- vised by the micro processor. This transducer has been put into use and proved to be satisfied in application.
