As engineers face increasing demands to optimize output from existing facilities, Coriolis flow meters have become increasingly popular. This proprietary measurement technology allows direct mass and density measurement with high accuracy, without requiring additional sensors to derive mass flow. Let’s explore an overview of this device through the following article.
Understanding Coriolis Flow Meters
Coriolis flow measurement is a precise method for measuring the flow of liquids and gases. Coriolis flow meters operate based on the principle of the Coriolis effect, in which the rotational movements of liquid or gas create a force acting on the measuring tubes, thereby determining the flow rate of the liquid or gas.
Basic Structure and Operating Principles of Coriolis Flow Meters
- Basic Structure: Includes single-tube, dual-tube, or quad-tube designs. These tubes typically vibrate when fluid passes through at a frequency determined by a driver.
- Coriolis Effect: When liquid or gas flows through the vibrating tubes, it creates a Coriolis force due to the interaction between the fluid movement and the vibrational movement of the tube. This force deforms the tubes in a specific way.
- Deformation Detection: Depending on the flow rate and mass of the liquid or gas, different deformations are produced. Through this analysis, the mass flow rate of the liquid or gas flowing through the tube can be calculated.
- Direct Mass Flow Measurement: Unlike other flow measurement methods, Coriolis flow measurement directly measures mass flow rather than volumetric flow.
