After a survey of the existing Coriolismass flowmeters, all based upon the elastic deformation of the resonant sensor, this paper describes anewtype of Coriolismassflowmeter realised, in a prototypal way, in the DIME laboratories. The flowmeter prototype is composed of two attached elements: a stiff tube and an original system of independent elasticsuspension which lets the whole sensor vibrate. In such a way, the newtype of elasticsuspension permits measurement independent from the elastic properties of the tube, not subject to deformation, realising anewmass flow sensor. The DIME prototype, which is described in the present paper, was studied and realised with the main aim of checking the mechanical behaviour of the newtype of uncoupled elasticsuspension. Being the prototype and not a production-engineered version, for which it is possible to provide the metrological performances, the DIME flowmeter was tested on the DIME calibration facility, and the experimental results, which prove the linear behaviour of the prototype, are reviewed.

Abstract
After a survey of the existing Coriolismass flowmeters, all based upon the elastic deformation of the resonant sensor, this paper describes anewtype of Coriolismassflowmeter realised, in a prototypal way, in the DIME laboratories. The flowmeter prototype is composed of two attached elements: a stiff tube and an original system of independent elasticsuspension which lets the whole sensor vibrate. In such a way, the newtype of elasticsuspension permits measurement independent from the elastic properties of the tube, not subject to deformation, realising anewmass flow sensor. The DIME prototype, which is described in the present paper, was studied and realised with the main aim of checking the mechanical behaviour of the newtype of uncoupled elasticsuspension. Being the prototype and not a production-engineered version, for which it is possible to provide the metrological performances, the DIME flowmeter was tested on the DIME calibration facility, and the experimental results, which prove the linear behaviour of the prototype, are reviewed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
