摘要
设计了一种新型的双时间法计数器 ,并成功地应用于检定脉冲型流量传感器 .试验表明 :该计数器性价比高 ,使用方便 ,工作可靠 ,可以缩短检定时间 ,在一定条件下 ,可用较小的标准容器检定较大口径的流量传感器 。
A new dual\|time method counter is designed in this paper. The counter can be used to calibrate the instrument coefficient for pulse\|type flow transducers. The results indicate that the instrument is reliable for work, convenient to use, and can be used to calibrate large\|bore flow transducers with smaller verified volumetric tank with shorter calibration time. Its measurement precision is higher than original method.
