1. The discovery of the Coriolis effect

The basis of the Coriolis mass flow meter is the Coriolis effect, which is a phenomenon: when flowing in a liquid or gas, a spiral Vortex will be formed in the fluid due to the centrifugal force and tangential force of the fluid. This phenomenon was first observed by French physicist Gustave-Gaspard de Coriolis in the mid-19th century. The Coriolis effect has wide applications in fields such as fluid mechanics and meteorology.

2. Interesting story about Coriolis mass flow meter

Although the Coriolis mass flow meter is a very important industrial instrument, there are some interesting stories associated with it. For example, in Sherlock Holmes, Sherlock Holmes uses a Coriolis mass flow meter to solve a murder. In addition, in some scientific experiments, Coriolis mass flow meters are also used to measure the breathing rate of salamanders to infer their energy consumption.

In the early 1960s, NASA needed an instrument that could accurately measure rocket fuel flow. Traditional measurement methods were not accurate for rocket engines, so NASA began looking for new ways to solve the problem. Scientists discovered the Coriolis mass flow meter, a new type of flow meter that can accurately measure the mass flow of fluids in pipes. NASA began to use this flow meter for rocket engine fuel flow measurement, which is very important to ensure that the rocket engine can accurately control thrust.

In the aerospace industry, Coriolis mass flow meters are widely used for fuel measurement. During a certain space mission, a spacecraft had a fuel calculation error, resulting in insufficient fuel. After investigation, it was discovered that the Coriolis mass flow meter was malfunctioning. In an emergency situation, engineers need to repair the flow meter in a very short period of time. However, they found that the parts that needed to be replaced could not be delivered in a timely manner through traditional logistics methods. So, they decided to use 3D printing technology to repair the flow meter by printing out corresponding parts. Finally, within an extremely limited time, they successfully repaired the flow meter and successfully completed the task. This story demonstrates the power of technology and the spirit of innovation, while also highlighting the importance of Coriolis mass flow meters in the aerospace industry.

During the 1969 Apollo 11 mission, NASA used Coriolis mass flow meters to control fuel flow to the lunar landing module engines. This flow meter also played a very important role in the historic moment of successful landing on the moon. Through the precise measurement of the Coriolis mass flow meter, the fuel of the lunar landing module can be precisely controlled, thus ensuring the success of the landing mission.

This story shows us the application of Coriolis mass flow meter in the field of science and technology, as well as its accuracy and reliability. It also shows us the power of technology, which can help humans achieve unprecedented feats.
