Embodiment Construction

[0078] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0079] Such as Figure 1-Figure 3 As shown, this embodiment provides a Coriolis mass flowmeter, which includes an upstream pipe joint 1, a downstream pipe joint 2, a housing 3, a fluid flow pipe 4, an excitation device, a detection device, a vibration isolation structure and an increaser. Heavy structure7. Wherein, the fluid flow tube 4 is installed in the housing 3, and the vibration isolation device is installed on the fluid flow tube 4 to separate the fluid flow tube 4 into a vibrating pipeline 47 and a non-vibrating pipeline 48. The fluid flow tube 4 An excitation device and a detection device are also installed on it. The excitation device is used to drive the vibrating pipeline 47 to vibrate. When the fluid material is introduced into the tube to make it flow forward along the tube, the vibrating tube will force the fluid to vibrate together. In o...

Abstract

The invention discloses a Coriolis mass flowmeter and a sensor assembly thereof. The flowmeter includes an upstream pipeline connector used for being connected to an upstream fluid pipeline and a downstream pipeline connector used for being connected with a downstream fluid pipeline. The sensor assembly is installed in a shell of the flowmeter and comprises a fluid flow pipe, a vibration isolationstructure, a weight addition structure and a connection structure; the fluid flow pipe is provided with a fluid input pipeline, a fluid output pipeline and a double loop pipeline connected between the input pipeline and the output pipeline in series; the vibration isolation structure at least includes a first vibration isolation piece which is fixedly arranged on the fluid flow pipe and divides the fluid flow pipe into a vibration pipeline and a non-vibration pipeline; the weight addition structure is arranged on the non-vibration pipeline, and the weight addition structure and the non-vibration pipeline are not in contact with the shell. One end of the connection structure is fixedly connected to the non-vibration pipeline, and the other end of the connection structure is fixedly connected to the upstream pipeline connector and / or the downstream pipeline connector to enable the non-vibration pipeline to be flexibly connected with the upstream pipeline connector and / or the downstreampipeline connector correspondingly.

Description

technical field [0001] The present invention relates to a Coriolis mass flowmeter, in particular to a sensor assembly with a fluid flow tube of a series double loop pipeline, and a Coriolis mass flowmeter with the sensor assembly. Background technique [0002] A Coriolis mass flow meter is an instrument that directly and precisely measures fluid flow. The main body of a typical Coriolis mass flowmeter structure uses two U-shaped tubes side by side, allowing the two tubes to vibrate at the same frequency and anti-phase at their resonant frequency, that is, they will move closer or open at the same time. If a fluid is introduced into the tube to flow forward along the tube while the vibrating tube vibrates synchronously, the vibrating tube will force the fluid to vibrate with it. In order to resist this forced vibration, the fluid will give the vibrating tube a reaction force perpendicular to its flow direction. Under this effect called the Coriolis effect, the vibrating tube...
