A study on the development of an electromagnetic flowmeter and the characterization of flow signal
전자기유량계의 개발및 신호 특성에 관한 연구
Abstract
An electromagnetic flowmeter(EMF) was developed and its characteristics were compared with a commercial EMF. The measuring tube of the EMF was basically designed as 100 m diameter. A signal processing circuit was also developed for generating the magnetic field and converting the flow signal to flowrate and flow quantity. To obtain a more stable and reliable flow signal, the double magnetizing frequency was adopted for magnetizing the coil of the EMF For the characterization of EU, the uncertainty of calibrator was estimated within
