History of Coriolis Flow Meters

At the core of many critical industrial processes lies the fundamental need for precision fluid measurement and control. This is the vital task fulfilled by the ingenious Coriolis flow meter – an advanced instrument designed specifically to measure true mass flow rate of liquids and gasses flowing through vibrating tubes. Unlike traditional volumetric flow meters relying solely on fluid velocity, Coriolis meters focus directly on harnessing the inertia of the fluid itself to deliver exceptionally accurate and reliable mass flow data. 

The conceptual foundations of Coriolis metering can be traced back to the pioneering work of French physicist Gaspard-Gustave de Coriolis in the early 19th century. He was first to describe the subtle twisting forces generated when analyzing motion in a rotating frame of reference – aptly termed the Coriolis effect. Yet it took modern technological advancements before this phenomenon was effectively harnessed, with the first Coriolis mass flow meters emerging in the late 1970s. Their debut revolutionized the industry by enabling a level of precision flow measurement previously unattainable.

Coriolis Meters – How Do They Work?

The ingenious operating principle behind Coriolis flow metering seems almost deceptively simple on the surface. As fluid travels through oscillating flow tubes, the vibration imparts an acceleration on the media particles. This creates a force that leads to the tubes subtly twisting in direct proportion to the mass flow rate. Highly sensitive sensors measure this minute tube deflection, capturing the Coriolis effect in action to derive an exceptionally accurate reading. 

In many ways, the effect is similar to the twist observed when spinning a ball on a string – the vibrating tubes cause fluid particles to veer off their straight trajectory. Carefully placed sensors determine the resulting phase shift between the tubes’ inlet and outlet sides. These tiny differential changes are then used to precisely calculate the true fluid mass traversing the system. The meter instantly translates these readings into mass flow measurements, while remaining immune to fluid variables such as temperature, pressure or viscosity fluctuations. 

What truly sets Coriolis technology apart is the incredible accuracy and reliability it brings to industries where highly accurate measurement is critical. Whether verifying custody transfer of high-value chemicals, controlling dosage in pharmaceutical manufacturing, or ensuring product quality in food and beverage production – Coriolis meters elevate process control and reduce costly errors. Their versatility also allows a single device to measure liquids, gasses and even slurries across a wide range of operating conditions. 

Additionally, the rugged design of Coriolis meters makes them suitable for the stringent demands of petrochemical plants and oil fields alike – able to withstand vibration, temperature swings and exposure to corrosive media. Combined with minimal maintenance needs and long service life, it’s easy to see why Coriolis meters have become an indispensable solution for precise process fluid measurement.

Coriolis Mass Flow Meter

This designation underscores the device’s ability to directly measure mass rather than volumetric flow rates of flowing fluids over time. This ability is crucial for processes where the exact mass impacts the outcome, such as in the precise mixing required in food production or chemical synthesis.

Generally speaking, Coriolis flow meters broadly covers the meter’s capability to gauge flow rates. It implies the technology’s adaptability in measuring both mass and derived volumetric flow rates, catering to a wide array of industrial applications. The application context and measurement accuracy requirements typically guide the preference for one term over the other.

Carefully position the meter in the designated location. Unlike other flow measurement technologies such as turbine or ultrasonic, the Coriolis meter does not require any minimum amount of straight rigid pipe upstream and downstream of the meter. When possible, installing a short straight run and the meter inlet and outlet is recommended, but not required.

Step 5: Connect the Meter 

Connect the meter to the piping system. Ensure all connections are secure and leak-free. Following the manufacturer’s guidelines for the type of connections and seals to use is crucial. 

Step 6: Power and Communication Connections 

Make the necessary electrical and data connections according to the manufacturer’s instructions. Make certain to do so in accordance with all applicable local electrical codes.

Step 7: Calibration and Testing 

Once installed, calibrate the meter if required. Then, conduct tests to verify that it is operating correctly and accurately measuring flow.

Overcoming Common Installation Challenges

Challenge: Vibrations and Pulsations 

Vibrations from nearby equipment or pulsations from pumps can affect meter accuracy. Solution: Install the meter away from sources of vibration or use anti-vibration mounts. Dampeners can help mitigate the effects of pulsations.

Challenge: Environmental Conditions

Extreme temperatures or humidity can impact the meter’s electronics. Solution: Install protective enclosures or shelters to shield the meter from environmental extremes.

By carefully following these steps and addressing common challenges, you can ensure the successful installation of your Coriolis flow meter, maximizing its performance and reliability in your application.
