Embodiment Construction

[0068] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0069] Such as Figure 1-4 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 order to...

Abstract

The invention discloses a sensor assembly for a Coriolis mass flowmeter. 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 to a downstream fluid pipeline. The axis of the upstream pipeline connector and the axis of the downstream pipeline connector are positioned on one central axis; the sensor assembly is arranged in a shell of the flowmeter and comprises a vibration part and a non-vibration part which are separated by a vibration isolation structure, and the gravity centerof the sensor assembly is basically positioned on the central axis. By positioning the gravity center of the sensor assembly basically on the central axis, when vibration leakage happens at the vibration part, since the gravity center of the sensor assembly is as close as possible to the central axis of the upstream and downstream pipeline connectors or is positioned on the central axis of the upstream and downstream pipeline connectors, the rotation radius of a sensor about the axis of an upstream and downstream junction is decreased. Therefore, no matter what causes vibration leakage of thevibration part of the sensor, vibration of the non-vibration part of the whole sensor is unlikely to happen, and the stability of the flowmeter is improved.

Description

technical field [0001] The 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 will pro...
