Coriolis flow meters are also referred to as simply mass flow meters, or even inertial flow meters, and they measure the rate of flow by the mass per unit time, otherwise known as the force of the acceleration.
The Coriolis flow meter gets its name from the Coriolis effect which is an inertial force that occurs due to the rotation of the Earth. In physics, this effect is described as the deflection of moving objects while the motion is relative to a rotating reference frame.
In layman’s terms this means that it is the force that is found in an object that is rotating. Read More…
The flow meter gets an accurate measurement of the mass flow in addition to a measurement of the overall density of the fluid.
Coriolis flow meters are a somewhat new type of flow meter as the first started to be used in the industrial industry in the 1980s, these flow meters are manufactured from a u-shaped tube which is filled with liquid.
It also contains a displacement sensor, a driving unit, as well as an inlet and outlet in order to encourage flow. Coriolis flow meters work by the flow causing the rotation of the u-tube and the sensors evaluating the difference of flow from the inlet of the tube to the outlet of the tube. The time delay between these two points is proportional to the mass flow rate of the substance.
We say substance because Coriolis flow meters work across a number of industries and applications and can measure the flow rate of various substances such as a broad range of fluids and gases from hydrogen gas to natural gas.
These flow meters are commonly constructed from corrosion-resistant materials like stainless steel or even hastelloy in order to prolong the life of the Coriolis flow meter.
In order to find the right flow meter for your application consult a flow meter manufacturer and they will let you know if a Coriolis flow meter is best for your specific application.
As always, understanding your application is the first step to finding the right flow meter for the job.
