Micro Motion flow meters are among the most trustworthy and advanced flow meter solutions available nowadays. It is Flow Meters for Mass, Volume & Density Measurement owned by Emerson. Micro Motion has released a variety of coriolis tools, led by the elite series meters that offer peak performance in a drainable design.
Known for their unmatchable accuracy and direct mass flow measurement, these devices have become an industry standard. This blog post provides a comprehensive look into micromotion mass flow meters.
Working Principle of Micromotion Mass Flow Meters
Motions of very short duration or length, especially periodic motion, are called micromotion. Micro motion coriolis flow meters are based on the principle of kinematics.
In a Coriolis flow meter, an actuator causes a small tube to vibrate continuously near its natural frequency. When the measured fluid enters the sensor, it is diverted to two parallel measuring tubes (vibrating tubes).
When measuring the flow, the drive coil excites the pipe to oscillate in opposite directions at the natural resonant frequency. Two sensors placed along the pipe measure the deflection of the vibrating tube over time. The time delay between the two sine waves is called the time difference (Delta-T), which is proportional to the mass flow rate.
Key components include:
- Support structure: The measuring tube is fixed to the support structure and serves as the vibration axis of the vibration system.
- Measuring tube (vibrating tube): It consists of two parallel curved tubes.
- Position detector: It is used to detect the twisting change of the measuring tube.
- Drive device: It generates electromagnetic force to drive the measuring tube to vibrate at a frequency close to the resonant frequency.
- Housing: It protects the measuring tube and the drive and detection device.
- Transmitter: Converts sensor signals into mass flow, density, and temperature readings.

Benefits of Using a Coriolis Flow Meter
A. Universal Fluid Compatibility
Micromotion flow meters can be used with virtually any liquid or gas, regardless of conductivity, viscosity, or phase.
B. Improved Process Control
It can directly measure the mass flow, temperature, and density of the fluid. This is of great significance to the measurement of energy and the detection and control of production processes such as chemical reactions.
C. Lower Total Cost of Possession
The high reliability and low maintenance needs of these meters reduce downtime and repair costs over time.
D. Intrinsic Safety Options
Suitable for use in hazardous locations, many models are certified to meet global safety standards including ATEX, CSA, and IECEx.
E. High measurement accuracy
The measurement accuracy can be guaranteed to be between 0.1% and 0.5%.
F. Low installation requirements
The installation requirements are not high, and there are no requirements for the upstream and downstream straight pipe sections. Reliable operation and low maintenance rate.
