Abstract

PROBLEM TO BE SOLVED: To provide a digital mass flowmeter whose reactivity, accuracy and adaptability are higher, as compared with those of conventional analog methods and to which a precise and elabolate control algorithm can be applied. SOLUTION: In a digital flowmeter 100, a vibratable conduit is contained, a drive circuit 115 which is connected to the conduit and which can be operated so as to give a motion to the conduit is contained, and a sensor 110 which is connected to the conduit and which can be operated so as to detect the motion of the conduit is contained. A digital controller 105 is connected across the drive circuit 115 and the sensor 110. The digital controller 105 contains a circuit, and the circuit receives a sensor signal from the sensor 110. A drive signal, which is based on the sensor signal, is generated by using a digital signal processing operation. The drive signal is output to the drive circuit 115. On the basis of the signal from the sensor 110, the measured value of the characteristic of a material flowing in the conduit is generated.
