초록

터빈유량계(Turbine flowmeter)는 유량 측정시 높은 정확도와 반복성을 위해 선택되지만 교정시의 표준 환경 조건과 현장에서의 환경 조건 차이로 다양한 측정 불확도 요인을 발생시킨다. 또한 교정된 측정값 외의 구간에서의 사용을 위해 신뢰성 높은 보간 기법(Interpolation method)이 필요하다. 따라서 본 논문에서는 유량 측정(Flow measurement) 신뢰성 향상을 위해 터빈유량계의 출력 신호의 정확한 측정과 교정된 결과값의 보간, 온도변화를 실시간 보정(correction)하는 장비를 설계 및 제작하고 성능 검증을 수행함으로 현장에서의 측정 신뢰도를 확보하였다.

The turbine flowmeter is selected for high precision and reproducibility at the time of flow rate measurement but causes various uncertainty factors of measurement in the difference between the standard environmental condition at calibration and the environmental condition at the site. Also, a reliable interpolation method is required for use in sections other than calibrated measurement values. Therefore, in this paper, in order to improve the reliability of the flow rate measurement, we designed and manufactured a device that accurately measures the output signal of the turbine flowmeter, interpolates the value of the calibrated result value, and corrects the temperature change in real time We confirmed the reliability of the measurement at the site to carry out the performance verification.
