This article will introduce the working principle, characteristics and significance of Coriolis mass flow meter in modern industry.

2. Working principle of Coriolis mass flow meter

1. operating principle

Coriolis mass flow meters use the Coriolis effect principle to measure fluid mass flow. When the fluid passes through the vibrating pipe, it is affected by the Coriolis force, causing the pipe to twist. By detecting the torsion angle and vibration frequency of the pipe, the mass flow rate of the fluid can be calculated.

2. Structure and measurement process

Coriolis mass flow meter mainly consists of measuring tube, driver, sensor and signal processing unit. The measurement process is as follows:

(1) The driver causes the measuring tube to vibrate periodically. (2) The fluid passes through the vibrating measuring tube and is affected by the Coriolis force, causing the tube to twist. (3) The sensor detects the torsion angle and vibration frequency of the pipe and converts them into electrical signals. (4) The signal processing unit processes and calculates the electrical signal to obtain the mass flow rate of the fluid.
