Design and Fabrication of the Coriolis Mass Flow Meter Measuring Tube

The measurement tube is the most important part of a Coriolis mass flow meter and directly influences the accuracy, stability, and long-term performance of the flow meter.
We perform Coriolis flow meter measuring tube production with inhouse quality control to deliver dependable mass flow measurement.

Precision Tube Forming Process

Our measuring tubes are fabricated from premium materials (stainless steel or special alloys) and tailored to the application requirements.
The geometry of each measuring tube is controlled in a very strict manner, by utilizing accurate tube forming and bending techniques, assuring a high level of repeatability in vibrational characteristics.

State-of-the-Art Forming Equipment and Skilled Technician Advantages:

• Constant tube thickness

• Symmetry (accuracy) of tubes

• Steady mechanical features

High accuracy and repeatability of measurements are required for these problems.

Welding and Structural Integrity

Vital welding processes taken place during the manufacturing process are tightly regulated to preserve tube strength and resilience to fatigue.
There is also a visual examination on every welded joint to check its integrity, which is very important for long-time running under pressure and temperature changing, even with shaking non-stop.

Dynamic Balancing and Frequency Matching

Measuring tubes are dynamic balanced and frequency tuned after being formed and welded.
This allows a stable oscillation status with minimal external disturbance, resulting in the accurate mass flow, density, and temperature of a Coriolis mass flow meter.
