What measurement can we get from Coriolis flow meter?
Mass Flow Rate
13.0 Mass Flow Rate A Coriolis meter utilizes a measurement technology which is capable of directly measuring mass flow (instead of inferring mass flow from volumetric flow and density). The Coriolis effect is the subtle correction to the path of moving objects to compensate for the rotation of the earth.
How does the Coriolis meter work?
A Coriolis meter is based on the principles of motion mechanics. When the process fluid enters the sensor, it is split. During operation, a drive coil stimulates the tubes to oscillate in opposition at the natural resonant frequency. As the tubes oscillate, the voltage generated from each pickoff creates a sine wave.
What type of meter is a Coriolis meter?
One such design is the Coriolis mass flow meter, which is widely considered the most accurate type of mass flow meter and is widely used in industrial applications for accurate measurement.
How does Coriolis meter work?
What is a Coriolis Meter? Coriolis mass flow meters work using the inertia caused by fluid or gas flowing through oscillating tubes. That inertia causes the tube to twist in proportion with the mass flow rate, and this twisting is measured with sensors to generate a linear flow signal.
How does a Coriolis meter operate?
What is the diameter ratio size used to determine the upstream and downstream straight pipe requirements?
In this case, you should use the 2/3 rule. Install the flowmeter with 2/3 of the pipe upstream of the meter and 1/3 of the pipe downstream of the meter.
Why choose Emerson Coriolis flow meters?
Superior Mass Flow and Density Measurement With Micro Motion Coriolis meters, Emerson provides a breadth of products that are tailored to your application needs. Our Coriolis flow meters are composed of a sensor, which contains the measurement tubes, and transmitter, which displays the outputs and allows the meter to be configured to your process.
What size Coriolis meter do I Need?
Coriolis meters are most popular in sizes of 1/16 inch through 6 inches. They are sometimes offered in larger sizes, but mechanical limitations begin to become onerous in these models. When a non-intrusive meter is desired in a size from 4 to 42 inches (or larger when required), another meter, such as the ultrasonic meter, should be used.
What is the TA-series Coriolis flow and density meter?
The TA-Series Coriolis Flow and Density meter has all wetted material constructed from pure tantalum, and is ideal for handling corrosive fluids such as acids and bases. Multiple line sizes are available to provide an ideal platform for batching, distribution, allocation and intra-plant measurement applications.
