Research On Calculations Of Coriolis Mass Flowmeter And Realization

Flow is an important factor which needs frequently measuring and controlling in the process of industrial produce. There are two types of flow meters, according to either the mass or the volume is measured. The Coriolis Mass Flowmeter (CMF) is an advanced mass flow meter based on the effect of Coriolis act. Since Micro Motion Company developed the first CMF in the late 1970's, it has quickly developed for its high precision in measuring mass flow. CMF is composed of first device and secondary device. First device includes vibrating tube, exciter and sensor. Secondary device is to deal with signals from the sensors, which is used to detect the vibration of the tube. The mass flowrate is proportional to the phase difference of the signals.The purpose of our research is to develop a new kind of digital CMF...
