Coriolis Flow Meter and How it Works


A Coriolis flow meter is a type of mass flow meter and calculates mass by means of inertia. The fundamental operation or function of this technology is founded on the concepts and ideas of motion mechanics.

As fluid pass or travel through a pulsating pipe, it’s bound to expedite as it travels toward the peak amplitudes point vibration. Conversely, slowing down fluid travels away from the peak amplitudes point vibration as it departs the pipe.

Coriolis flow meters, although regarded the most precise flow meters, are sensitive to failures when bubbles and particles are, for the most part, present in the fluid. The particles can, more often than not, build “splashing” within the pipe, create noise, and alter the energy required for the vibration in the tube. For more information, we will walk you through some vital info about Coriolis flow meters.

How It Works

Coriolis flow meters calculate or gauge the force occurring from the acceleration resulted by mass moving away from or toward a core of the rotation. This force or outcome can be, for the most part, experienced or encountered when riding a merry-go-round ride.

Thus, going toward the center will, more often than not, cause an individual to lean into the rotation to keep and sustain balance. When we talk about flow meters, the impact can be explained by flowing or running water in a coil of flexible hose that’s moved back and forth with both hands in front of the body.

Since the water is running away and toward from the hands, conflicting forces are, for the most part, produced and made the hose to bend. In this kind of flow meter technology, the swinging movement is created by the vibrating tubes for which the liquid pass through. The total number of twist is equivalent to the mass flow rate of liquid traveling through the pipe.

Pros and Cons

Coriolis mass flow meters can deal with sanitary applications, has high accuracy, low maintenance, very reliable, and is suitable for custody transfer. For the production of energy, mass flow is, for the most part, more crucial compared to volume fluids.

These cover natural gas and petroleum liquids, both liquefied and compressed. The drawbacks of this technology include high cost, high viscosity fluids, and you may want to consider pressure drop for “U” shaped pipelines.

How To Use

This flow meter technology or gauge the mass flow of liquids, for example, gases, vapors, chemicals, caustics, acids, and water. Since the mass flow is calculated, the measurement or estimation isn’t influenced by the changes in the fluid density.

Be specifically mindful and thorough when utilizing this technology to measure vapor flows and gas flows as the flow rates have a tendency to be, where accuracy is downgraded, low in the flow range. Additionally, in vapor and gas applications, huge pressure drops over the flow meter, and its corresponding piping can happen.

Coriolis mass flow meters can be, for the most part, used to vapors, gases, corrosive liquids, cryogenic, and sanitary tubes at least 12 inches. The most common applications are, more often than not, found in the petrochemical, chemical, petroleum, paper, pulp, power, mineral processing, mining, wastewater, and water industries.

Components of construction are, for the most part, restricted to Hastelloy C. Straight-tube and stainless steel designs. They are available to calculate and assess some abrasive or dirty liquids.

Most application for this flow meter technology is discovered in chemical processes where fluids can be caustic and, in another way, challenging to measure. Additionally, the comparative insensitivity to density enables this flow meter technology to be used in applications wherein the, more often than not, physical aspects of the fluid aren’t popular or prominent. Further, Coriolis mass flow meters can be applied in chemical feed systems as well.


The industries that can use or apply this flow meter technology include wastewater and water, metals and mining, power, pulp and paper, pharmaceutical, food and beverage, oil and gas, and chemical industries.

How To Install

This flow meter must be installed or mounted so that it’ll continue to be permeated of liquid and, of course, so air can’t get confined in the pipes. For sanitary fittings, the Coriolis flow meter must be drained or emptied entirely. The most common installation is, more often than not, vertical tubes with an upward stream. However, horizontal tubes are also acceptable. What’s not advisable is to install this technology in vertical tubes with a downward stream.

Coriolis mass flow meters are, for the most part, applied in many challenging, critical applications, in trades including life sciences, food, and beverage, chemical, power, water, and wastewater, as well as oil and gas industries. Several generally known applications for this flow meter technology include challenging slurry, gas, and liquid applications, fiscal custody transfer, and applications with low to high flow rates.
