How to improve the design efficiency of metal rotor flowmeter?

Project Overview

Among flowmeter instruments, the metal rotor flowmeter is a very frequently used instrument. It is commonly used for measurements in various industries. Such as petroleum, chemical industry, water treatment and other complex and harsh environmental conditions

The metal rotor flowmeter is a traditional variable-section flowmeter. It has the advantages of simple structure, reliable operation, small pressure loss and stability, and can measure low flow media. Widely used to measure high temperature, high pressure and corrosive fluid media. It is determined by the measurement principle and usually requires vertical installation. However, in some specific industrial applications, it is necessary to install the float flowmeter horizontally. Although its measurement principle is the same as the classic vertical float flowmeter, it is a specially constructed float flowmeter that can be installed in horizontal pipes.

The overall design and research of the metal rotor flowmeter is based on the previous Bernoulli equation, which requires that the fluid motion is a constant flow and the fluid is an ideal fluid (an ideal fluid refers to a fluid whose viscosity is ignored). It is an incompressible homogeneous fluid, but the fluid flowing through the float flowmeter does not strictly meet these three conditions. The design of the traditional flowmeter requires experiments to verify and modify the design drawings, which not only prolongs the design cycle, but also increases design costs. In order to solve the above two reasons, computational fluid dynamics is introduced into the design of metal rotameter. Then numerically simulate the flow field of the float flow sensor, and evaluate the preliminary sample design through comparison of simulation and experimental data, thereby optimizing the structural parameters of the flow sensor and making the design of the flow sensor more reasonable, thereby greatly improving the design efficiency and further Solve the problem.
