Coriolis Mass Flow Meter

Fluid is being pumped through the mass flow meter. When there is mass flow, the tube twists slightly. The arm through which fluid flows away from the axis of rotation must exert a force on the fluid, to increase its angular momentum, so it bends backwards. The arm through which fluid is pushed back to the axis of rotation must exert a force on the fluid to decrease the fluid's angular momentum again, hence that arm will bend forward.

    The mass flow meter does not measure the volume per unit time (e.g., cubic meters per second) passing through the device; it measures the mass per unit time (e.g., kilograms per second) flowing through the device. Volumetric flow rate is the mass flow rate divided by the fluid density. The mass of the fluid would not be changed with temperature, pressure, or composition, for example. The fluid may also be a combination of phases such as a fluid with entrained bubbles.

What is Coriolis Effect

Coriolis Effect:

    In physics, the Coriolis effect is a deflection of moving objects when they are viewed in a rotating reference frame. In a reference frame with clockwise rotation, the deflection is to the left of the motion of the object; in one with counter-clockwise rotation, the deflection is to the right. Although recognized previously by others, the mathematical expression for the Coriolis force appeared in an 1835 paper by French scientist Gaspard-Gustave Coriolis, in connection with the theory of water wheels. Early in the 20th century, the term Coriolis force began to be used in connection with meteorology.

    Newton's laws of motion describe the motion of an object in a (non-accelerating) inertial frame of reference. When Newton's laws are transformed to a uniformly rotating frame of reference, the Coriolis and centrifugal forces appear. Both forces are proportional to the mass of the object. The Coriolis force is proportional to the rotation rate and the centrifugal force is proportional to its square. The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object's speed in the rotating frame. The centrifugal force acts outwards in the radial direction and is proportional to the distance of the body from the axis of the rotating frame. These additional forces are termed inertial forces, fictitious forces or pseudo forces. They allow the application of Newton's laws to a rotating system. They are correction factors that do not exist in a non-accelerating or inertial reference frame.

DifferenceS between Coriolis Mass Flow Meter and the Volumetric Flow Meters

Compared to this, For the Volumetric Flow Meters:

1. We could randomly say that all the other types of flow meters except the Coriolis mass flow meters belong to the Volumetric Flow Meters, including the Thermal Mass Flow Meters, Turbine Flow Meters, Electromagnetic Flow Meters, Vortex Flow Meters, Rotameters, etc.

2. The Volumetric Flow Meters will directly measure the "Volume " of the measured medium. The "Volume" of the medium WILL BE affected by the factors of  temperature, pressure, density, viscosity, etc.

3. The measurement of the Volumetric Flow Meters WILL BE influenced by the factors of temperature, pressure, density, viscosity, etc. And the compensation calculation IS REQUIRED.

4. The accuracy of the Volumetric Flow Meters is said to be reached by ±0.5%, ±1%. While, the actual accuracy is hard to reach the promised level of accuracy. Because the accuracy will be influenced by factors of temperature, pressure, density, viscosity, etc.

Why choosing the Coriolis Mass Flow Meters instead of the other types of flow meters?

For the Coriolis Mass Flow meters:

1. The measuring principle of the Coriolis Mass Flow Meter is the Coriolis Force principle. The Coriolis mass flow meter will directly measure the "Mass " of the measured medium. The "Mass" of the medium will NOT be affected by the factors of  temperature, pressure, density, viscosity, etc.

2. The measurement of the Coriolis Mass meters will NOT be influenced by the factors of temperature, pressure, density, viscosity, etc. And the compensation calculation is NOT required.

3. The accuracy of the Coriolis Mass Flow Meters is ±0.1%, ±0.15%,  ±0.2% optional. The accuracy will NOT be influenced by the factors mentioned above.

KunLun Company is the manufacturer of producing Coriolis Mass Flow Meters

 We have particular professional formula to produce the measuring pipeline compared to the other producing factories. Zeropoint Stability is good. Medium with tiny flow rate could be measured precisely, which reaches a minimum of 0- 1kg/h. Gas with either low pressure or with high pressure could be measured as well. Give us your problems, and you will never be disappointed
