Coriolis Flow Meter Working Principle
SmartMeasurement’s Coriolis principle provides direct mass flow measurement by detecting the Coriolis forces generated when fluid moves through vibrating tubes. As the fluid flows, it induces a twisting motion proportional to its mass flow rate, which is detected by sensors measuring the phase shift between inlet and outlet vibrations. This direct mass measurement allows the meter to provide highly accurate, repeatable readings of mass flow, density, and temperature simultaneously. The result is precise, multi-variable data ideal for critical applications such as dosing, blending, and custody transfer in industries like oil and gas, pharmaceuticals, food and beverage, and chemical processing.
