Please refer to the answer as below
A Coriolis transmitter is a component of the Coriolis flowmeter. It transmits the information gathered by the flow tube sensors. This type of flow meter is used to measure the mass flow rate and density of a fluid.
Flow meter categories based on fluid Some flow meters can be easily eliminated because they simply will not work with the application. For instance, electromagnetic flow meters will not work with hydrocarbons and require a conductive liquid to function. Many flow meters cannot measure gases or slurries. Listed below are some of the main flow meter categories paired with the fluid type the meters can handle. Gas – Coriolis Mass, Thermal Mass, Ultrasonic, Variable Area, Variable Differential Pressure, Positive Displacement, Turbine Liquid – Coriolis Mass, Thermal Mass, Ultrasonic, Variable Differential Pressure, Positive Displacement, Turbine, Electromagnetic Slurry – Coriolis Mass, some subsets of Variable Differential Pressure, Electromagnetic, Ultrasonic Vapour – Vortex, Ultrasonic, Diaphragm, Floating Element
Coriolis Flow Meters Pros Extremely accurate Low maintenance Can handle a wide spectrum of flow ranges Compatible with many dirty, corrosive & difficult to handle fluid types Versatile installation—no straight pipe runs required\ Serviceable without removing from pipeline Easy in-field calibration Capable of measuring gases as Cons Expensive initial investment Not suited for low-pressure gases Limited to certain pipe sizes Coriolis meters, more commonly known as mass meters, differ from other meter types in that they measure mass flow instead of volume flow. These meters also feature a unique means of calculating flow rate based upon the Coriolis Principle.

Coriolis Flow Meter. A single or dual tube is located inside the pipeline of each Coriolis flow meter. An exciter causes the tube to oscillate constantly. If there is now flow, the tube oscillates uniformly. As soon as the flow starts to flow in the tube, an additional twist is imposed on the oscillations as a result of liquid inertia. Sensors are located at the inlet and outlet of the tube and register this basic oscillation precisely. Now due to the Coriolis effect, the inlet and outlet sections of the tube oscillate in different directions at the same time. Highly sensitive sensors pick up this change of time and space. This is called a phase shift. This is a direct measurement of how much gas, the liquid is flowing through the pipe. Higher the phase shift, the more the flow in the tube vice versa. Density can also be measured by measuring the oscillation frequency. The frequency of oscillations for water-filled tube is more, whereas honey-filled tube is less. This is due to the density difference. Advantages: Coriolis flowmeter is insensitive to viscosity, pressure, and temperature. Coriolis flowmeter can be configured to measure flow in either the forward or reverse direction. Coriolis flowmeter can be configured to measure flow in either the forward or reverse direction. Coriolis flowmeters do not have any internal obstructions that can be damaged or plugged by viscous slurries or other types of particulate matter in the flow stream. The operation of the flowmeter does not depend on the Reynolds number. Coriolis flowmeters provide a direct mass flow measurement without the addition of any external measurement instruments. They display outstanding accuracy. The flow meters are highly linear over the entire flow range. Rangeability is on the order of 20:1. Coriolis flowmeters have been successfully applied at flow rates 100 times lower than their rated scale flow rate. The operation of the flow meter is independent of flow characteristics such as turbulence and flow profile. Therefore, the requirement of upstream and downstream straight pipe run requirements and flow conditioning is not required. Limitation of Coriolis Flowmeters: Coriolis flowmeters are expensive. Coriolis flowmeters are difficulty in measuring the flow rate of low-pressure gas. Coriolis flowmeters are not available for the large pipelines.

You may not know it, but Emerson Automation Solutions’ Micro Motion flow meter is quite an impressive little device. This brand putted the first Coriolis flow meter on the market. Now, you can find many vendors selling similar flow meters, but Emerson did it first. As the name denotes, the Micro Motion flow meter uses the Coriolis effect to measure. Coriolis flow meters provide some of the most accurate measurement on the market. They can measure flow and density, and you can find patented technologies on some devices that measure viscosity as well. We have a definitive guide to Coriolis Micro Flow meters here, if you want to check out our in-depth discussion about this type of flow meter. The Coriolis Effect – The Micro Motion flow meter’s working principle The Micro Motion flow meter’s measuring tube comes in a variety of shapes, and vendors have sales pitches for each of them. So you’ll have to decide for yourself which suits your purposes best. The most common is the omega or “U” sensor. Whatever the shape, the tube has a drive coil to vibrate the tube at a specific frequency. And at the inlet and outlet ends of the tube, you find pick offs measuring this frequency. If there’s no flow, then both pick offs of the Micro Motion flow meter vibrate at the same frequency, creating identical waveforms. When you have flow, it creates the Coriolis effect, a small twist that phase-shifts the waveforms from the pick offs. Thus, by measuring the amount of shift, you can calculate the mass flow rate. And as for density, you’ll use the natural change of frequency that occurs in a change of fluid density. High density makes the frequency decrease, and low makes it increase. The Micro Motion flow meter uses these changes to find the density of the product with great accuracy.
