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. The mass flow rate is the mass of the fluid traveling past a fixed point per unit time.
Ultrasonic flow meter; Mass flow meter (Coriolis force). Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area.
Its products include thermal mass flow controllers/meters, Coriolis mass flow controllers/meters, variable area meters (aka rotameters), level products, direct liquid injection systems, and more. A range of accessories such as pressure controllers, valves, and secondary instrumentation is also offered.
Therefore, the resonant frequency is directly affected by the density. Higher density media causes a larger Coriolis effect if the volumetric flow rate is constant. Flowing media causes a frequency and a phase shift of the bent pipe, which are proportional to the mass flow rate of the sample. Coriolis meters measure the mass flow of the system.
A practical application of the Coriolis effect is the mass flow meter, an instrument that measures the mass flow rate and density of a fluid flowing through a tube. The operating principle involves inducing a vibration of the tube through which the fluid passes.
Coriolis meters can handle a wide range of flow rates and have the unique ability to output mass flow - this gives the highest accuracy of flow measurement currently available for mass flow measurement. Since they measure flowing density, coriolis meters can also infer gas flow rate at flowing conditions.
