Coriolis Flow Meter Concepts

The video explains how a Micro Motion Coriolis flow meter measures mass flow and density using dual parallel flow tubes. The process fluid is split between the tubes, which oscillate to generate sine waves. The phase shift between these waves indicates mass flow, while wave frequency indicates density. An analogy with a spring and weight system helps explain the relationship between mass, density, and frequency. The video concludes with the calculation of volume flow and the meter's applications.

What is the primary function of the dual parallel flow tubes in a Coriolis flow meter?

• To increase the fluid pressure

• To filter impurities from the fluid

• To split the fluid and measure mass flow and density

• To measure temperature changes

How do Coriolis forces affect the flow tubes in the meter?

• They cause the tubes to expand

• They induce a twisting motion in the tubes

• They make the tubes vibrate at a lower frequency

• They stop the tubes from oscillating

What does a phase shift in the sine waves indicate in a Coriolis flow meter?

• The mass flow rate

• The fluid's viscosity

• A change in fluid color

• A change in fluid temperature

What is the relationship between delta T and mass flow rate in a Coriolis flow meter?

• Delta T is equal to mass flow rate

• Delta T is unrelated to mass flow rate

• Delta T is directly proportional to mass flow rate

• Delta T is inversely proportional to mass flow rate

In the spring and weight analogy, what does the mass of the tubes and fluid represent?

• The weight at the end of the spring

• The length of the spring

• The spring constant

• The elasticity of the spring

What remains constant in the flow tubes, affecting the frequency of oscillation?

• The stiffness of the flow tubes

• The temperature of the fluid

• The pressure inside the tubes

• The color of the fluid

How is liquid volume flow derived in a Coriolis flow meter?

• By measuring the fluid's color

• By calculating from mass flow and density

• By assessing the fluid's temperature

• By evaluating the fluid's viscosity

What can be said about fluids with the same volume but different densities?

• They have the same mass

• They have different masses

• They have the same temperature

• They have different colors

What is one of the key benefits of using a micro motion Coriolis meter?

• It requires no maintenance

• It provides highly accurate mass flow and density measurements

• It can only be used for water

• It is less expensive than other meters
