Mass Flow Meter Working Principle Animation

Differential pressure techniques can be used for indirect mass flow measurement of steam but as mentioned above direct mass flow measurements are much better than indirect mass flow measurement.

Mass flow meter working principle animation. The animations on the right do not represent an actually existing coriolis flow meter design. Coriolis flow meters measure real mass flow whereas thermal mass flow meters are dependent of the physical properties of the fluid. Mass flow meters are the types of flow meters which are mainly employed in mass related processes such as chemical reactions heat transfer etc. When there is mass flow the tube twists slightly.

As fluid moves through a vibrating tube it is forced to accelerate as it moves toward the point of peak amplitude vibration. 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 meter does not measure the volume per unit time e g cubic meters per second passing through the device. This is the principle of operation of a de laval nozzle.

The purpose of the animations is to illustrate the operating principle and to show the connection with rotation fluid is being pumped through the mass flow meter. In all these processes accurate measurement of flow is the prerequisite. When there is mass flow the tube twists slightly. Coriolis flow meter principles the basic operation of coriolis flow meters is based on the principles of motion mechanics.

The mass flow rate is the mass of the fluid traveling past a fixed point per unit time. Fluid is being pumped through the mass flow meter. Vortex flow meters are ideal for steam flow measurement because other mass flow meters or volumetric flow meters cannot measure steam. There are numerous types of mass flow meters available in the industry.

However mass flow rate for a compressible fluid will increase with increased upstream pressure which will increase the density of the fluid through the constriction though the velocity will remain constant. True mass flow measurement is an important development across industry as it eliminates inaccuracies caused by the physical properties of the fluid not least being the difference between mass and volumetric flow. However the most widely used type is the coriolis meter. Conversely decelerating fluid moves away from the point of peak amplitude as it exits the tube.
