Abstract

The invention provides for a quasi-linear tube Coriolis mass flowmeter (CMF), which is used for direct high-accuracy measure for mass flow and comprises two quasi-linear tube measuring tubes with the same structure in parallel, a vibration exciter, two detectors, four distance plates, two flanges, two end connecting tubes, two shunts and four matching blocks. The quasi-linear tube Coriolis mass flowmeter (CMF) can effectively improve the properties and quality factors of a resonance sensor, greatly reduces volume of a flowmeter, lowers flow field influence, and has small flow resistance, low pressure loss and simple installation and processing; the measuring tube has favorable dynamic equilibrium, can measure the liquid mass flow with high viscosity and high impurity content, further expands the application range of the CMF and satisfies the industrial development requirements on accuracy and range of flow measurement; and the invention plays a greater role in saving raw materials, lowering production cost, reducing environment pollution, improving profit margin and promoting product quality.

Description

technical field

[0001] The invention relates to a Coriolis mass flowmeter (CMF), in particular to a straight-tube type Coriolis mass flowmeter, which belongs to the field of testing and measuring instruments and is used for direct and high-precision measurement of mass flow. Background technique

[0002] The development of mass flow measurement technology is the focus of the development of national science and technology in the field of process control. In order to achieve high-accuracy and high-reliability measurement of various media under complex environmental conditions, Coriolis Mass Flowmeter (Coriolis Mass Flowmeter, CMF, also known as Coriolis mass flowmeter) has become one of the important development technologies in this field because of its superior performance, and it meets the major needs of the country. CMF can directly measure the mass flow of the fluid in the pipeline with high accuracy, and use the Coriolis effect generated when the fluid flows through the v...
