What makes the TCF series Coriolis flowmeter exceptionally accurate for gas measurement?

Answer: Measuring gases with a Coriolis flowmeter is inherently more challenging than measuring liquids. The TCF series overcomes these challenges and achieves exceptional gas measurement accuracy through an advanced Triple-Compensation System:

• Temperature Compensation: Temperature fluctuations alter the material properties of the measuring tube. The TCF series compensates for this via built-in sensors, and coupled with advanced structural design, it minimizes the temperature effect on accuracy to as low as ±0.00015% of the maximum flow rate per °C.
• Pressure Compensation: Changes in process pressure can cause microscopic variations in the stiffness and shape of the measuring tube. The TCF series allows for fixed or dynamic pressure compensation (e.g., via PLC/DCS) to effectively eliminate these errors.
• Sound Velocity Compensation: This is the most critical factor for gases. Unlike incompressible liquids, gases are highly compressible, meaning the gas’s center of mass does not vibrate perfectly in sync with the measuring tube. This causes deviations in vibration characteristics and errors in mass and density readings. Our sound velocity compensation algorithm corrects this phenomenon, drastically enhancing gas measurement precision.
