High-Precision Coriolis Mass Flow Measurement
The Coriolis Mass Flow Meters patented and developed by our company represent a leading solution for high-precision flow measurement across demanding industrial applications.
These meters provide direct and simultaneous measurement of mass flow, volume flow, density, and temperature for liquids and slurries—without requiring additional instruments, manual calculations, or compensation algorithms.
Thanks to their advanced sensor design, the meters deliver exceptional accuracy with minimal pressure drop, making them suitable for both process control and critical measurement tasks.
Designed for reliable operation in harsh industrial environments, the meters feature:
No moving parts, ensuring long-term stability and minimal maintenance
No special mounting or flow conditioning requirements
Stainless steel wetted parts as standard
A wide range of process connections to accommodate various installation needs
These characteristics make the Coriolis Mass Flow Meter an ideal choice for applications requiring measurement certainty, process reliability, and operational efficiency.

Mass Flow Meter Features
Unlike differential pressure or volumetric flow meters, Coriolis mass flow meters measure mass flow directly, not inferred from velocity or volume.
True mass flow measurement – unaffected by temperature, pressure, or density changes
High accuracy and repeatability – ideal for custody transfer and critical dosing
Multi-variable output – mass flow, density, and temperature from a single instrument
No flow profile requirements – minimal straight pipe length
For engineers, a Coriolis meter is not just a flow sensor, but a process integrity instrument.
Coriolis Effect-Based Mass Flow Detection- Working Principle
The Coriolis Mass Flow Meter consists of a pair of precisely formed bent measuring tubes, which are driven to vibrate at their natural resonant frequency.
When fluid flows through the vibrating tubes, Coriolis forces are generated as a result of the interaction between tube vibration and fluid movement. These forces cause a torsional deformation of the tubes, producing a measurable phase shift between the inlet and outlet sections.
Key operating principles include:
The measuring tubes are excited into stable vibration
Fluid flowing through the tubes generates Coriolis force
The Coriolis force causes symmetric tube deflection about the centerline
Displacement sensors mounted on both sides of the tubes detect this deformation
The resulting electrical signals are processed to calculate mass flow directly
In addition, the vibration frequency of the tubes is used to determine fluid density, while integrated temperature sensors provide accurate process temperature measurement.
This measurement method enables direct, real-time mass flow measurement, independent of fluid properties such as viscosity, pressure, or temperature.
Coriolis Mass Flow Meter – Application Optimization
Coriolis mass flow meters are especially suitable for applications where high accuracy, direct mass measurement, and long-term stability are critical. The CMF125 is widely used across industries that demand reliable performance under complex process conditions.

Can Coriolis mass flow meters operate reliably at high temperatures?
Yes. Coriolis mass flow meters are well suited for high-temperature applications, with operating ranges extending up to several hundred degrees Celsius depending on configuration. Because mass flow measurement is based on tube vibration rather than fluid properties, accuracy remains stable even under thermal variation.
How does a Coriolis flow meter perform under high pressure conditions?
Coriolis flow meters are designed with robust tube structures and high-strength materials, enabling operation at pressures up to tens of MPa. Measurement accuracy is unaffected by pressure changes, making them ideal for high-pressure chemical, oil, and energy systems.
Is Coriolis technology suitable for high-viscosity fluids?
Yes. High-viscosity fluids do not impact measurement accuracy because Coriolis meters measure direct mass flow, not velocity. This makes them especially effective for oils, polymers, resins, syrups, and other viscous or non-Newtonian fluids.
Can Coriolis mass flow meters handle multiphase or slurry media?
Coriolis meters perform well with liquids containing suspended solids or slurries, as long as the flow remains reasonably homogeneous. The measurement principle is independent of flow profile, making it more stable than differential pressure or turbine meters in complex media.
How do Coriolis meters maintain accuracy under changing process conditions?
Because Coriolis flow meters directly measure mass flow and density, they are inherently immune to variations in temperature, pressure, and fluid properties. This eliminates the need for compensation calculations and ensures consistent long-term measurement stability.
Are Coriolis flow meters suitable for safety-critical or continuous processes?
Yes. With no moving parts, minimal maintenance requirements, and excellent repeatability, Coriolis mass flow meters are widely used in safety-critical and continuous industrial processes where measurement reliability and uptime are essential.
