Coriolis flow meters, also known as Coriolis mass flow meters, are instruments used to measure the mass flow rate of fluids. They operate on the principle of the Coriolis effect, which is the deflection of a fluid’s motion caused by the rotation of the Earth.
Coriolis flow meters consist of a pair of vibrating tubes through which the fluid flows. When the fluid flows through the tubes, it causes a twisting or bending motion in the tubes. This motion is detected by sensors, typically placed at the inlet and outlet of the tubes.
By measuring the phase shift and magnitude of the tube motion, Coriolis flow meters can determine the mass flow rate of the fluid. Additionally, these meters can provide measurements of density, temperature, and sometimes even viscosity.
Uses of Coriolis flow meters
Coriolis flow meters have a wide range of uses in various industries and applications. Some of the common uses of Coriolis flow meters include:
Oil and Gas Industry
Coriolis flow meters are used for accurate measurement of petroleum products, such as crude oil, refined fuels, and natural gas. They are commonly used in custody transfer applications, where precise measurement is crucial for billing and inventory purposes.
Chemical Processing
Coriolis flow meters are widely utilized in chemical plants to measure the flow of various chemicals, solvents, acids, and alkalis. They provide accurate measurements even with aggressive and corrosive fluids.
Pharmaceutical and Biotechnology
Coriolis flow meters are utilized in pharmaceutical and biotech industries for measuring the flow of fluids in manufacturing processes, such as the production of pharmaceutical ingredients, vaccines, and biologics.
HVAC and Building Automation
Coriolis flow meters are utilized in heating, ventilation, and air conditioning (HVAC) systems for measuring the flow of chilled water, hot water, and thermal energy. They help in optimizing energy efficiency and monitoring system performance.

Here are the Best 10 Coriolis Flow Meters for your different applications.
1. Coriolis Mass Flow Meter
Coriolis Mass Flow Meters consist of bended tubes that detect Coriolis force generated by fluid flow. Vibrating tubes and flowing fluid create a synthesized force, causing the tubes to shift symmetrically. Displacement sensors on the tubes detect this force and produce electric signals, which are regulated to measure mass flow directly.
2. Sanitary and hygienic Coriolis flow meter
Sanitary and hygienic Coriolis flow meters feature tri-clamp end fittings and 316L SS wet parts for food, dairy, and pharmaceutical applications, providing accurate measurement for batch control and custody transfer.
3. Asphalt /bitumen flow meter
Asphalt flow measurement poses challenges due to high viscosity and poor fluidity. Conventional liquid flow meters struggle to meet bitumen flow measurement requirements due to its high viscosity and the presence of solid particulate impurities. Bitumen flowmeter easily measure this.
4. High pressure Coriolis mass flow meter
Coriolis mass flow meters are ideal for high-pressure fluid measurement, offering high accuracy, repeatability, and stability. They have no flow blocking elements, making them reliable for high-pressure and high-viscosity fluid flow in the petrochemical industry.
5. Small Coriolis flow meter/flow controller
While conventional Coriolis flow meters are used for large flow measurements, SH-CMF-FE applies Coriolis flow technology to very low flow rates. It integrates PID control and batch functions for ultra-low flow control and feeding, serving as a P&ID mass flow meter.
6. Bent tube Coriolis flow meter
The SH-CMD Series bent tube Coriolis flow meter is designed for tough fluid measurements, such as high viscosity or high-pressure media. It directly measures fluid mass flow without requiring pressure, temperature, viscosity, or density correction. SH-CMD mass flow meters employ digital drive, DSP signal processing, and a special structure for high stability and seismic performance.
7. Refrigerant mass flow meter
These flow meters are typically installed in the refrigerant lines and utilize various measurement techniques, such as thermal, ultrasonic, or differential pressure, to accurately determine the flow rate. By monitoring the flow of refrigerant, these meters enable technicians and engineers to optimize system performance, detect any abnormalities or inefficiencies, and ensure that the cooling or heating requirements are met.
8. High Viscosity Flow meter
When dealing with high-viscosity liquids, it is crucial to select an appropriate flow meter. Many flow meter types are unsuitable for high-viscosity fluids. High-viscosity fluids demand additional power to pump, and conventional velocity flow meters struggle with measurement. Designers and operators should consider viscosity when selecting flow meters for fluids over 100 mPa·s.
9. CNG mass flow meter
These flow meters are well-suited for measuring the flow of high-pressure gases like CNG, accurately measuring the mass flow rate regardless of changes in temperature or pressure. The deflection of a vibrating tube caused by the gas flow is detected to measure mass flow directly.
10. Fuel Oil Mass Flow Meter
Fuel oil mass flow meters are specifically designed to measure the mass flow rate of fuel oil in various industrial applications, including power generation, marine transportation, and oil and gas production.
