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 flowmeters are high-precision instruments that directly measure mass flow by leveraging the Coriolis effect. As fluid passes through vibrating sensor tubes, the Coriolis force causes the tubes to twist, creating a phase shift that is directly proportional to the mass flow rate, while the vibration frequency simultaneously allows for precise density measurement. Because they operate independently of fluid temperature, pressure, viscosity, or flow profile, they are widely utilized in critical industries such as oil and gas custody transfer, chemical processing, pharmaceutical manufacturing, and high-accuracy food and beverage blending.
ADVANTAGES
- 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.
- 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.
- Besides mass flow measurement, density and temperature, and even consistency can also, be picked up and output.
