CoriolisVibrationssensors

Coriolis vibration sensors, also known as Coriolis mass flow meters or Coriolis meters, are instruments used to measure mass flow rate and other physical properties. They operate based on the Coriolis effect, a phenomenon where a moving object appears to be deflected from its path when viewed from a rotating frame of reference. In a Coriolis sensor, a fluid is made to oscillate through a vibrating tube. As the fluid flows through this vibrating tube, it experiences a Coriolis force perpendicular to both its direction of motion and the direction of vibration. This force causes a slight twist or deflection in the tube.

The magnitude of this twist is directly proportional to the mass flow rate of the fluid. By measuring the extent of this deflection, often using sensors placed at strategic points on the tube, the mass flow rate can be accurately determined. Beyond mass flow, Coriolis meters can also measure fluid density. Changes in fluid density will affect the natural frequency of the vibrating tube and the magnitude of the Coriolis-induced twist, allowing for density determination. This dual capability makes them versatile for various industrial applications, including chemical processing, oil and gas, and food and beverage industries, where precise measurement of flow and density is crucial.
