Intelligent corrosion-resistant anti-interference vortex precession flowmeter and processing and assembling process

Abstract

The invention provides an intelligent corrosion-resistant anti-interference vortex precession flowmeter and a processing and assembling process. The intelligent corrosion-resistant anti-interference vortex precession flowmeter comprises a vortex precession housing, a vortex generation body, a sensor and a control system. The vortex generation body is arranged in the vortex precession housing, the sensor is fixed on the exterior of the vortex precession housing and is electrically connected with the vortex generation body, the sensor is electrically connected with the control system, the vortex generation body is manufactured by means of a composite casting process, the body cavity of the vortex precession housing and the vortex generation body are both subjected to surface hardening and corrosion resisting processes, a control module of the sensor employs a 16-bit MSP430F5438A single-chip microcomputer, the MSP430F5438A single-chip microcomputer employs a compiler and can provide an IARWorkbench system having the C language standard characteristic, and program software of the control system is compiled through the C language. The intelligent corrosion-resistant anti-interference vortex precession flowmeter has performances of intelligence, corrosion resistance, anti-interference, noise reduction, full functionality and low power consumption and the like.

Description

technical field [0001] The invention relates to the technical field of manufacturing general machinery and fluid control equipment, in particular to an intelligent corrosion-resistant and anti-interference precession vortex flowmeter and its processing and assembly process. Background technique [0002] As clean energy gradually enters people's lives and grows stronger day by day, the exploitation and transportation of various natural gas needs some measuring instruments to measure. At present, the commonly used measuring instruments in the market are precession vortex flowmeters, and this type of flowmeter basically uses The aluminum-based alloy is used as the matrix, and integrated control is adopted. Due to factors such as the flow range of the medium, pressure changes, and changes in the straight pipe section, measurement errors will occur; Factors such as interference will also interfere with the normal working state of the flowmeter, causing certain errors in the flowm...

[0002] As clean energy gradually enters people's lives and grows stronger day by day, the exploitation and transportation of various natural gas needs some measuring instruments to measure. At present, the commonly used measuring instruments in the market are precession vortex flowmeters, and this type of flowmeter basically uses The aluminum-based alloy is used as the matrix, and integrated control is adopted. Due to factors such as the flow range of the medium, pressure changes, and changes in the straight pipe section, measurement errors will occur; Interference and other factors will also interfere with the normal working state of the flowmeter, causing a certain error in the flowmeter

[0003] One of the main parts of the flowmeter, the vortex generator, is generally made of aluminum-based alloys. Aluminum-based alloys are soft, light, easy to process, and low in cost. However, currently in the precession vortex flowmeter In the production process, the most difficult part to process is the vortex generator, which is mainly manifested in the following two problems: First, because the blades o
