Abstract

The invention discloses a double-parameter precession mass flow meter for variable component gas measurement, which comprises a main body, wherein the top of the main body is fixedly connected with adetection module, the bottom of the detection module is fixedly connected with a detection probe, and the bottom end of the detection probe penetrates through the top of the main body and extends to an inner cavity of the main body. The invention relates to the technical field of flow meters. According to the double-parameter precession mass flow meter for variable component gas measurement, a mounting plate and a connecting piece are mounted through a mounting bolt, the mounting plate is locked in the connecting piece, the mounting plate extrudes the connecting plate inwards at the moment, the connecting plate moves along an inserting rod to extrude a sealing washer, and the sealing washer expands to seal a gap, so that the installation of a rectifying body and a vortex generating body iscompleted, the fixation of the vortex generating body and the rectifying body is realized, the abrasion of the vortex generating body and the rectifying body is greatly reduced at the same time, theoperation is simple, the use is convenient, the overall air tightness is ensured while the fixation is convenient, and the gas leakage is prevented from influencing the monitoring effect.

Description

technical field [0001] The invention relates to the technical field of flowmeters, in particular to a dual-parameter precession mass flowmeter for variable-component gas measurement. Background technique [0002] The precession vortex flowmeter is a new type of gas flow meter that adopts advanced micro-processing technology and has the advantages of strong function, wide flow range, simple operation and maintenance, and convenient installation and use. The main technical indicators have reached the advanced level of similar foreign products. The flow meter adopts advanced micro-processing technology, which has the advantages of strong function, wide flow range, simple operation and maintenance, and convenient installation and use. [0003] Among the existing precession vortex flowmeter products, the anti-vibration and anti-interference ability is poor, the pressure loss is large, the interference caused by external mechanical vibration or internal air flow cannot be eliminat...
