Liquid Mass Flow Meter working principle

Coriolis mass flowmeters measure the force resulting from the acceleration, caused by mass moving toward (or away from) a center of rotation.

This effect can be experienced, when riding a merry-go-round, where moving toward the center will cause a person to have to “lean into” the rotation so as to maintain balance.

As related to flowmeters, the effect can be demonstrated by flowing water in a loop of flexible hose, that is “swung” back and forth in front of the body with both hands. Because the water is flowing toward and away from the hands, opposite forces are generated and cause the hose to twist.

They represent about 21% of all flowmeters sold.

In a Coriolis mass flowmeter, the “swinging” is generated by vibrating the tube(s) in which the fluid flows.

The amount of twist is proportional to the mass flow rate of fluid passing through the tube(s).

Sensors and a Coriolis mass flowmeter transmitter are used to measure the twist and generate a linear flow signal.

How do you calculate mass flow rate?

As shown, when a mass point of mass m moves at a velocity υ in a pipe that rotates at an angular velocity ω for the p-axis, the particle is subjected to acceleration of two components and its force.

a. The normal acceleration is the centripetal force acceleration αr, the magnitude of which is equal to ω2r, the direction is toward the P axis;

b. Tangential acceleration αt is the Coriolis acceleration, the magnitude of which is equal to 2ωυ, and the direction is perpendicular to αr.

Due to the compound motion,

Coriolis Fc=2ωυm acts on the αt direction of the particle, and the pipe acts on the particle with a reverse force of -Fc= -2ωυm.

How do you calculate mass flow rate?

When a fluid of density ρ flows at a constant velocity in a rotating pipe, any pipe of length Δx will be subjected to a tangential Coriolis force of ΔFc.

Where A is the cross-sectional area of the pipeline. Since the flow rate of the mass flow meter is δm, δm=ρυA.

Therefore, directly or indirectly measuring the Coriolis force generated by the flowing fluid in the rotating pipe can measure the mass flow, which is the basic principle of the Coriolis mass flowmeter.

However, it is difficult to generate Coriolis force by the rotary motion.

At present, the product is replaced by a pipe vibration, that is, a thin-walled measuring tube fixed by two broken ends,at the midpoint of the measuring tube resonance or near resonance frequency.

Excitation, the fluid flowing in the tube generates Coriolis force, causing the opposite direction of deflection in the front and rear half points of the measuring tube. And electromagnetically detecting the amount of deflection to obtain mass flow.

Since the density of the fluid affects the vibration frequency of the measuring tube, and the density has a fixed relationship with the frequency, the mass flow meter can also measure the fluid density.
