What is the Coriolis principle for mass flow meter?

Have you ever wondered how mass flow meters work? One of the most common principles used in mass flow meters is the Coriolis principle. If you are curious about what this principle is and how it applies to mass flow meters, then you have come to the right place. In this article, we will delve into the Coriolis principle for mass flow meters, exploring the concept, its applications, and its significance in the field of flow measurement.

Understanding the Coriolis Principle

The Coriolis principle, named after French engineer Gaspard-Gustave de Coriolis, is a fundamental concept in physics and engineering. It describes the behavior of objects in a rotating frame of reference, such as the Earth's rotation. According to this principle, when an object moves within a rotating system, it experiences a force due to the system's rotation. This force is known as the Coriolis force, and it is perpendicular to the object's velocity. In the context of mass flow meters, the Coriolis principle is utilized to measure the mass flow rate of a fluid passing through a vibrating tube.

The Coriolis principle is based on the conservation of angular momentum. When a fluid flows through a vibrating tube in a mass flow meter, it causes the tube to twist in proportion to the mass flow rate. This twisting motion is directly related to the Coriolis force experienced by the fluid in the rotating frame of reference. By measuring the degree of twisting, the mass flow meter can accurately determine the mass flow rate of the fluid. In essence, the Coriolis principle provides a direct and precise method for measuring mass flow, making it a valuable tool in various industrial applications.
