Since it has excellent accuracy and immunity to processing variables (pressure, temperature, and flow profile), corolis flow meter is commonly used in many applications scenarios. The coreolis flow meter was not widely accepted until two applications helped it to establish itself in the marketplace.
Brief history of flow measurement
Early flow measurement relied exclusively on mechanical flowmeters to measure flow. Flow meters measured flow volume and velocity based on swept volumes and timers. Flow sensors in the early days operated like containers and timers. They started together, and as soon as the container was full, they stopped. The fill time divided the volume of flow, producing a flowrate.
Whenever the flow continued to occur, the technology advanced to support a continuous filling and emptying system, rather than just dumping the filled containers.
These meters provided great performance, were simple, less costly, and easy to service, and were capable of measuring volume, time, and movement.
With that, technology provided more electronic choices such as pressure-based flow, open-channel level, vortex, magnetic, thermal mass, and many more. Despite all these technological advances, no meter suited a variety of applications, despite their numerous advantages in reliability, accuracy, repeatability and ownership costs. Earlier meters relied on volume- and velocity-based systems, so it was always possible to project errors when dealing with volume-changing variables in the process, like pressure, temperature, and speed.
The Coriolis flow measurement technique
The early versions of Coriolis flow technology were sceptical, unlike prompt flow and weight measurement methods. As the technology of Coriolis came into existence, it appeared too good to be true. Since the accuracy level and flexibility of application was unprecedented, it appeared too good to be true. Early Coriolis sensor prices went up due to a reluctance to embrace the potential technology.
Coriolis meters, however, began to be welcomed by the chemical industry after their trials proved they were more accurate and more reliable than any meters ever used before.
When it came to transportation, recovery, and processing of oil and gas, precision and repeatability were not viewed as critical requirements. There were high profits, stable markets, and time-honored measurement methods.
The value of petroleum products has risen rapidly since the 1970s, and the government has implemented stricter guidelines to ensure compliance with flow rate measurements.
During that time Coriolis flow sensors were experiencing substantial improvements, including improvements in accuracy, features for measuring temperature and densities, and the ability to measure gases and liquid fluids, such as CNG flow meters.
Besides that, Coriolis flow value was improved even more when there were gas voids present in the liquid flow stream. Extensive noise filters and algorithms improved the corolis flow meter value by reducing process noise.
Chemical processing benefits from coriolis
A benefit of Coriolis sensors for chemical manufacturers was the end of the issue of frequent adjustments and tweaks needed when using many volumetric flow sensors in areas of conditional flow accuracy regarding flow temperature and pressure.
Coriolis sensors came about as a way to curb costs of startups and services needed by the chemical industry because of issues like endless adjustments, insufficiencies, and volumetric flow sensors requirements.
Moreover, many chemical recipes require mass measurement. Because Coriolis meters can measure both mass and density in situ, the chemical industry considered them very suitable for a variety of chemical processes. They are also commonly used as flow meters for high viscosity fluids.
Since volumetric flow sensors are always prone to shortcomings, requirements, and adjustments, Coriolis sensors became a potential way for the chemical industry to cut costs, since they allowed increases in uptime and reduced service costs.
As Coriolis flow sensors are basically pipe pieces, nothing sticks out of the flow stream, reducing pressure loss and making maintenance easier.
