Title:

FIXING DEVICE FOR FLOWMETER COMPONENT

Document Type and Number:

WIPO Patent Application WO/2021/098334

Kind Code:

A1

Abstract:

Embodiments of the present invention provide a fixing device for a flowmeter component, comprising two fixing supports. The two fixing supports are fixed on both sides of a flowmeter component; each of the fixing supports is provided with connection arcs, and the connection arcs are axisymmetric in the vertical direction. When the flowmeter component is a driver on a Coriolis mass flowmeter, the two fixing supports are respectively fixed on both sides of the driver, and the driver is fixed to a flow tube of the Coriolis mass flowmeter by means of the connection arcs on the fixing supports, so as to complete mounting and fixing of the driver. The structure enables the connection stiffness of the fixing supports and the flow tube to be symmetric about the midplane of the flow tube, avoids undesirable deformation produced during working vibration of the flow tube, and improves the zero stability and overall performance of the Coriolis mass flowmeter.
