Embodiment Construction

[0030] Install according to the drawings and instructions:

[0031] (1) inlet joint, (2) inlet dynamic seal hinged pipe, (3) inlet measuring tube, (4) inlet sensor, (5) inlet dynamic seal hinged elbow, (6) vibration tube, (7) vibration driver, (8) Outlet dynamic seal hinged elbow, (9) Outlet sensor, (10) Outlet measuring tube, (11) Outlet dynamic seal hinged tube, (12) Outlet joint, (13) Shell, (14) Fixed plate.

[0032] Working process of the present invention is as follows:

[0033] 1. Mass flow measurement:

[0034] 1. The inlet measuring tube and the outlet measuring tube are filled with fluid. When the fluid is not flowing, the two measuring tubes move symmetrically with equal amplitude under the action of the driving force, and the phase difference measured by the two sensors is zero.

[0035] 2. When the fluid in the measuring tube flows, the two measuring tubes move with equal amplitude under the action of the driving force. According to the working principle of the ...

Abstract

The invention relates to a Coriolis mass flowmeter connected through a dynamic seal hinge. The flowmeter is characterized by comprising an inlet connector, an inlet dynamic seal hinge pipe, an inlet measurement pipe, an inlet sensor, an inlet dynamic seal hinge elbow, a vibration pipe, a vibration driver, an outlet dynamic seal hinge elbow, an outlet sensor, an outlet measurement pipe, an outlet dynamic seal hinge pipe, an outlet connector, a shell and a fixing plate. Compared with an existing Coriolis mass flowmeter, the dynamic seal hinge pipe-type Coriolis mass flowmeter has the following advantages that the elastic modulus of a system approaches to zero, and the measurement precision can be greatly improved; the measurement pipes are hinged to the exterior through dynamic seal, and theexternal vibration interference can be greatly lowered; measurement is unrelated to the elastic modulus of a material and also unrelated to change of the environmental temperature, and a temperaturecompensation circuit can be reduced; all components are machined parts, the precision of the components can be conveniently improved, and the consistency of each flowmeter is improved.

Description

[0001] (1) Technical field [0002] The present invention relates to mass flow meters, particularly Coriolis mass flow meters. [0003] (2) Background technology [0004] The Coriolis mass flowmeter is an instrument that directly measures the mass flow rate by using the principle of the Coriolis force proportional to the flow rate generated by the fluid flowing in the vibrating measuring tube. [0005] There are many forms of Coriolis flowmeter structure, generally composed of measuring tube and converter. The measuring tube has several single-tube shapes such as U-shaped, Ω-shaped, ring-shaped, straight-shaped and spiral-shaped, and double-tubes are also available. [0006] The measuring tubes are now fixedly connected to the inlet and outlet pipes of the fluid. Due to the fixed connection and the processing errors of the measuring tubes, it is difficult to improve the measurement accuracy of the measuring tubes, and it is often difficult to improve when it reaches 0.05%. ...
