Micro Motion Coriolis Flow Meter is a flow meter made according to the Coriolis acceleration theory. Z-Series Straight Tube Micro Motion Coriolis Flow Meter simultaneously measures mass flow, density, temperature and viscosity.

Z-Series Straight Tube Micro Motion Coriolis Flow Meter

The Z-Series Straight Tube Micro Motion Coriolis Flow Meter can directly measure the mass flow rate of the fluid in the closed pipe and the density of the medium. No front/rear straight pipe length requirements. The measurement principle is completely unaffected by the physical properties of the fluid and the flow field. Can measure various liquid and gas flow.

Micro Motion Coriolis Flow Meter Working Principle

The micro-motion mass flowmeter is a flowmeter made according to the Coriolis acceleration theory. There is a straight tube that rotates in a plane around a fixed axis O at an angular velocity w, and a particle in the tube moves outwards along the straight tube at a speed v. Because The mass point m is in a system with both rotational motion and linear motion, so it will obtain two accelerations.

Serving size:

① Centripetal acceleration a, its value is rw^2 (r is the distance from the particle m to the axis O), and the direction points to the axis O.
② Tangential acceleration ac, its value is 2uw. The direction is perpendicular to a, it comes from the rotating pipe. At the same time it produces a reaction force to the pipe. This reaction force is the Coriolis force. Its calculation formula is:

F=2muw —————-(3-8)

Where:
F is Coriolis force, N;
w is the angular velocity, 1/s;
u is the radial velocity in the rotating system, m/s,
m is the mass of the moving object, kg.

If the density of the fluid is p, the tangential Coriolis force on any section of pipe △x is:

△F=2pA△xuw ———(3~9)

Where:
A is the cross-sectional area of ​​the pipe.

In the formula (3-9), pAu is the natural flow rate of the fluid, set as QM’, then the formula (3-9) can be expressed as:

△F= 2w△xQm————-(3-10)

From the above equation, we can know the mass flow Qm as long as the Coriolis force △F is measured. This is the measuring principle of micro-motion mass flowmeter.
