脉冲型流量传感器检定仪的设计和应用

Design and Application of Calibrator of Pulsed Flow Transducer

利用双时间法设计了用于检定脉冲型流量传感器仪表系数的检定仪。可用较小的标准容器校验较大口径的流量传感器。试验表明 ,该检定仪使用方便、工作可靠、计数精度高 ,并可缩短检定时间。

By using dual timing method the calibrator for calibrating coefficient of instrument of pulsed flow transducer is designed.Thus larger bore flow transducers can be calibrated in smaller standard vessel.The test shows that the calibrator features ease use,reliable operation,high accuracy and faster calibration.
