Abstract

The invention provides a Coriolis force mass flowmeter. The Coriolis force mass flowmeter comprises a cylinder body, a measuring pipe arranged in the cylinder body, a driving part which is arranged in the middle of the measuring pipe and can stimulate deformation vibration of the measuring pipe and a driving deflection detection sensor which is arranged in the cylinder body and is used for detecting the movement of the driving part, wherein an additional vibrator is further fixedly arranged at the portion, corresponding to the driving part, of the middle of the measuring pipe, and has sensitivity to Coriolis force, and the sensitivity of driving vibration is low. Due to the design of the additional vibrator, the Coriolis force mass flowmeter is sensitive to Coriolis force, and the sensitivity of the driving vibration is low, and Coriolis force can be detected with high precision.

Description

technical field [0001] The invention relates to a flowmeter, in particular to a Coriolis force mass flowmeter. Background technique [0002] In the pharmaceutical, food and other industrial fields, it is very important to determine the flow in the pipeline for the monitoring, control and production of the process. The mass flow in pipelines is usually measured by flowmeters. The flowmeters commonly used in closed pipeline systems can be divided into electromagnetic flowmeters, ultrasonic flowmeters, matrix flowmeters and Coriolis flowmeters. [0003] Coriolis flow meters have many advantages over other flow meters. It can measure mass flow very accurately by a direct method, while other types of flowmeters can only measure volume flow and require additional calculations to convert to mass flow, and the measurement principle of the Coriolis flowmeter is related to the physical properties of the fluid Regardless, it will not be affected by changes in pressure, density and te...
