Coriolis Mass Flowmeters: Precision Measurement for Critical Applications

Understanding Coriolis Technology

Coriolis mass flowmeters directly measure mass flow rate, density, and temperature simultaneously. Unlike volumetric flowmeters, they are unaffected by changes in fluid properties such as viscosity, pressure, or temperature.

How Coriolis Meters Work

The meter uses vibrating tubes through which the process fluid flows. The Coriolis effect causes a phase shift in the tube vibration proportional to the mass flow rate. Advanced sensors detect this phase difference with exceptional precision.

Unique Benefits

• Direct mass flow measurement
• Multi-variable measurement (mass, density, temperature)
• High accuracy (±0.1% of rate)
• Independent of fluid properties
• No straight pipe requirements

Industry Applications

Coriolis flowmeters are essential in oil and gas custody transfer, chemical batching, pharmaceutical production, and food processing where precise mass measurement is critical for quality control and regulatory compliance.

Installation Best Practices

Ensure proper orientation to avoid gas entrapment, provide adequate support to minimize external vibrations, and consider temperature effects on meter housing. Regular zero calibration maintains optimal accuracy.
