Flow, whether volumetric or mass, is one of the most measured variables in industrial processes. Water, natural gas, steam, oil, chemicals, and wastewater are just a few examples of the different liquids or gases that are measured on a daily basis. As there is no universal technology suitable for all of these applications, we offer you the support to choose the right tecnology and sizing.
Coriolis Mass Flowmeters
Measurement Principle
Coriolis flowmeters have one or two measuring tubes where an exciter installed inside the sensor causes it to oscillate at resonance frecuency. When fluid begins to flow into the measuring tube, additional torque is imposed due to the inertia of the fluid. Two sensors detect this change in tube oscillation in time and space as the "phase difference". This difference is a direct measure of the mass flow. Additionally, the density of the fluid can be determined from the frequency of the measuring tubes oscillation. The internal temperature is also recorded to compensate for thermal influences.
