Their dynamic range stems from the linear nature of the signal they produce while measuring flow.Ĭoriolis flow meters find utility in diverse, demanding applications, spanning industries such as oil and gas, water and wastewater, power generation, chemical processing, food and beverage production, and life sciences. Coriolis meters can measure flow rates ranging from just a few grams per hour to an astounding 120,000 pounds per minute. With an extensive range of line sizes, they offer exceptional flow measurement precision and turndown capabilities, making them a staple in various industries. Conversely, as the fluid decelerates, it moves away from this point of peak amplitude, resulting in a twisting reaction of the flow tube during its journey through each vibration cycle.Ĭoriolis flow meters are essential across a broad spectrum of flow measurement applications. As the fluid courses through this tube, it experiences acceleration as it approaches the point of maximum vibration amplitude. These meters operate by harnessing the mechanics of motion within a vibrating tube. Principles of Coriolis Flow Meter TechnologyĪt the heart of Coriolis flow meter technology lies the fundamental principles of motion mechanics. The time delay between these two sine waves, known as Delta-T, is directly proportional to the mass flow rate. These oscillations generate a voltage through each pickoff, creating sine waves that reflect the motion of one tube relative to the other. However, Coriolis flowmeters have an easier time with liquids. During operation, a drive coil stimulates the tubes, causing them to oscillate in opposing directions at their natural resonant frequency. Coriolis flowmeters can measure both liquids and gases. The mass flow rate is the mass of the fluid traveling past a fixed point per unit time. With Coriolis instruments, the sensor tube is set into vibration by an actuator. Challenges to face with a Coriolis flow meter. Because the Coriolis principle directly measures the mass flow, Coriolis flow meters can be used for both gases and liquids. When the process fluid enters the sensor, it undergoes a split. A mass flow meter of the Coriolis type A mass flow meter, also known as an inertial flow meter, is a device that measures mass flow rate of a fluid traveling through a tube. Thermal mass flow meters are mainly used for gases. A Coriolis meter is rooted in the principles of motion mechanics.
