Coriolis flow meter
In the field of precise measurement for industrial production, the Coriolis flow meter has become a key piece of equipment due to its outstanding performance. In the chemical industry, it can stably measure complex media such as acid-base solutions and viscous slurries, solving the problem that traditional flow meters are easily affected by medium viscosity and ensuring precise and controllable feeding into reaction kettles. In the food and pharmaceutical industries, its all-stainless-steel material meets hygiene standards, enabling dead-angle-free measurement of fruit juices, liquid medicines, etc., to avoid medium contamination and ensure product safety. In the energy industry, whether it is crude oil, natural gas or liquefied petroleum gas, it can achieve high- precision measurement, helping enterprises accurately calculate energy consumption and reduce cost losses.
Compared with traditional flow meters, it does not require straight pipe section installation, saving space and adapting to complex working conditions. It comes with dual-parameter measurement functions for temperature and density, enabling one-stop acquisition of multi- dimensional data and reducing equipment investment. Moreover, it has the advantages of strong anti-interference capability and long maintenance cycle, which significantly lowers the operation and maintenance costs of enterprises. Truly, it provides strong support for improving production efficiency and quality control in various industries.

Vibration: Inside the meter, one or two metal tubes are vibrated by an electromagnetic driver (like a tuning fork). In a “no-flow” state, the tubes vibrate evenly.
Flow & Twist: As fluid or gas flows through these vibrating tubes, the moving mass resists the vibration. This resistance creates a Coriolis Force, which causes the tubes to “twist” or “wobble” slightly.
Phase Shift: Sensors at the inlet and outlet of the tube detect this twist. The time difference between the vibration at the start and the end of the tube is called the Phase Shift. This shift is directly proportional to the Mass Flow Rate.
