Abstract

THE EFFECT OF INTERNAL TEMPERATURE LOADS ON ORIFICE FLOWMETER

Liang-Huai Tong, Su-Lu Zheng*, Jian Fan, Xiu-Qin Chen, Hao-Nan Xu, Jiang-Bo Tong

ABSTRACT

Orifice flowmeter has a wide range of applications, it can be applied to all single-phase fluids (liquid, gas, steam) and part of miscible flow, the diameter and working state (temperature and pressure) of general production process can be measured. In order to study the influence of different temperature loads on the accuracy of the orifice flowmeter under certain pressure load on the inner wall of the orifice flowmeter pipeline, the three-dimensional model of the orifice flowmeter is analyzed by using simulation software, and the ability of the orifice flowmeter to withstand loads under natural conditions is analyzed. It is found that the locations of the maximum stress and displacement of orifice flowmeter occur at the inner wall of pipeline and inlet, and the maximum strain occurs in the shell. The maximum stress, displacement and strain of the orifice flowmeter increase with the increase of the temperature load when the pressure load is 0.1 MPa and keeps constant.
