The basic operation of coriolis mass flow meters is based on the principles of motion mechanics.
Coriolis flow meter working principle animation.
Curved tube coriolis flow meter.
The largest coriolis flow meter that is currently available has a maximum flow rating of 25 000 lb min 11 340 kg min and is equipped with 6 in.
The animations on the right do not represent an actually existing coriolis flow meter design.
Fluid is being pumped through the mass flow meter.
Coriolis flow meters are not available for large pipelines.
The sensor signal is fed into the integrally mounted pc board.
The purpose of the animations is to illustrate the operating principle and to show the connection with rotation.
The animation on the right represents how curved tube mass flow meters are designed.
A single or dual tube is located inside the pipeline of each coriolis flow meter.
Coriolis flow meter principles the basic operation of coriolis flow meters is based on the principles of motion mechanics.
When there is mass flow the tube twists slightly.
An actuator not shown induces equal counter vibrations on the sections parallel to the axis to make the measuring device less sensitive to outside vibrations.
An exciter causes the tube to oscillate.
Coriolis mass flow meter contains a vibrating tube in which a fluid flow causes changes in frequency phase shift or amplitude.
Conversely decelerating fluid moves away from the point of peak amplitude as it exits the tube.
Coriolis mass flow meter working pricipciple.
As fluid moves through a vibrating tube it is forced to accelerate as it moves toward the point of peak amplitude vibration.
