What is the Coriolis Mass Flow Meter?
A Coriolis mass flow meter is a highly accurate device used to measure the mass flow rate of fluids, including both liquids and gases. It works on the Coriolis flow meter working principle, which states that when a fluid flows through a vibrating tube, the inertia from the mass of the fluid creates a measurable deflection in the tube. This deflection is directly proportional to the mass flow rate, allowing the meter to measure mass flow and density precisely, regardless of the fluid’s properties.

The Use of a Coriolis Flow Meter
Coriolis flow meters are widely used in industries where precise measurement of mass flow is crucial. They are particularly effective in applications such as chemical processing, oil and gas, food and beverage production, and pharmaceuticals. These meters ensure the accurate dosing of liquids, maintain the correct chemical mixture, and help manage critical fluid transfers in various operations. However, it is essential to consider the Coriolis flow meter advantages and disadvantages when selecting the appropriate flow measurement technology for specific applications.
Why Coriolis Mass Flow Meter?
The Coriolis mass flow meter applications is favored because it measures flow rate directly in terms of mass, not volume, which ensures higher accuracy, especially in conditions where fluid density, pressure, or temperature can vary. It requires minimal maintenance, has no moving parts that wear out, and offers reliable performance across a wide range of fluids, making it suitable for challenging applications involving corrosive liquids or high-viscosity substances.
How a Coriolis Mass Flow Meter Works
A Coriolis mass flow meter operates on the Coriolis effect, a physical phenomenon that causes moving objects (like fluids) to experience a deflection in their path due to the Earth’s rotation. This principle is applied to measure the mass flow rate of a fluid within a pipe. Here’s how it works in a flow meter:
- Flow Tube Vibration:
The meter contains a flow tube that vibrates at a specific frequency. The fluid flows through the vibrating tube, which is typically in a U-shape or straight design. - Coriolis Effect (Deflection):
As the fluid flows through the vibrating tube, the flow causes a phase shift in the tube’s vibration, which is proportional to the mass flow rate of the fluid. The greater the flow rate, the larger the deflection or shift in the vibration. - Measurement of Phase Shift:
Sensors located on the flow tube detect the time difference between the vibrations of the upstream and downstream sections of the tube. This time difference is directly related to the mass flow rate of the fluid passing through the meter. - Density and Temperature Compensation:
In addition to measuring mass flow, Coriolis meters can also measure the density and temperature of the fluid. These values allow for more accurate measurements, especially in varying process conditions, and can help with the calculation of the volume flow rate as well. - Output:
The deflection data is processed by a transmitter that calculates the mass flow rate, and displays the results in real-time. The meter provides direct mass flow readings without the need for calibration or compensation for temperature and pressure fluctuations.
Key Advantages
- Direct Mass Flow Measurement: Unlike traditional flow meters that measure volume flow and require temperature and pressure compensation, Coriolis meters directly measure mass flow.

Coriolis Flow Meter Applications & Installation
When installing Coriolis flow meter applications, it’s crucial to consider factors such as fluid properties, pipe size, and process conditions. These meters are versatile and can be installed in various orientations (horizontal or vertical) without requiring significant lengths of straight pipe runs.

The Principle of Coriolis Flow Measuring
The Coriolis flow meter measures mass flow based on the Coriolis effect. Inside the meter, a vibrating tube distorts in response to the flow of fluid. The amount of distortion is directly related to the mass of the fluid passing through the tube. The meter uses sensors to detect this distortion and calculate the mass flow rate and fluid density in real time. This principle allows the Coriolis meter to deliver accurate readings without needing compensation for temperature or pressure variations.
