Coriolis Mass Flowmeter

Coriolis Mass Flowmeter

GENERAL INFORMATION

Mass Flowmeter is designed according to the principle of Coriolis force. Under the alternating current effect, the magnet and coil installed on the measuring tube will make two parallel measuring tubes vibrate according to some fixed frequency. Once there is flow passing through the pipes, Coriolis force will give rise to deflection (phase shift) on the vibration of two pipes and the deflection of vibration is directly proportional to the mass flow of fluid. Pick up them and the mass flow rate could be calculated.

BRIEF INTRODUCTION

Coriolis Mass Flowmeter is designed according to the Coriolis principle. It can be widely used for the process of detecting and custody transfer/fiscal unit in many industries such as petroleum, petroleum and chemical, chemical industry, pharmacy, paper making, food and energy, and so on. As a fairly advanced kind of flow measurement instrument, it has been paid attention to by the circle of measurement and accepted by many customers at home and abroad.

ADVANTAGES

Compared with the traditional flow measurement method, Mass Flowmeter has the following obvious merits:
-Enable to measure of the direct mass flow rate of fluid in the pipeline without changing any parameters, which avoids some measurement errors of intermediate links. Its mass flowrate
can be high accuracy and good repeatability within a bigger range of turndown ratio.
-Fluid measured can be more extensive, such as the steady uniform flow of common viscosity
fluid, the high viscosity fluid, non-Newtonian fluid, slurry containing some solid components, and the liquid containing some trace of gas.
-Due to the small vibration, the measuring tube of the Mass Flowmeter can be regarded as a nonmoving part, which will reduce the maintenance of the flowmeter, and enhance its stability and lifetime.
-Besides the mass flow measurement, the density and temperature, and even consistency can also, be picked up and output.
