摘要
The present invention is a Coriolis mass flowmeter which comprises at least one flowtube through which a fluid to be measured is allowed to flow; a number of force drivers for vibrating the flowtube in at least one mode of vibration of the flowtube; the vibration of the flowtube causing a driven deflection of the flowtube and the fluid flowing through the vibrating flowtube generating Coriolis forces which cause a Coriolis deflection of the flowtube; a plurality of strain-sensing transducers connected to the flowtube for generating signals representative of the driven deflection of the flowtube and the Coriolis deflection of the flowtube; and a signal processing circuit connected to the strain-sensing transducers for producing an indication of the mass flow rate of the fluid from the signals generated by the strain-sensing transducers.
