In the flow measurement field, Coriolis flowmeters are highly reliable and proven technology. This flow meter technology is best known for its consistency and accuracy. However, until recently, Coriolis flow meters were not used for plants or factories that could only shelter two-wire devices because of many reasons.

A lot of facilities lack the required rack space when planning to replace legacy two-wire flow meters caused by years of unmined cable to update to standard four-wire Coriolis flow meters. And, even though plant managers can say they’re merely utilizing what’s available, the truth is, they’ll continue to experience accuracy issues, unexpected shutdowns, and more.

Many facilities need to look for ways to boost efficiencies with fewer people, and budgets are getting tighter. So, how can you resolve this? In this post, we’ll walk you through the advanced wiring technologies for Coriolis flow meters. Read on!

Reliability

In the first place, what makes this technology extremely reliable? Well, the clear answer is that the coriolis flow meters have no moving parts that need replacement or servicing. However, there is much more to the story.

Although the actual Coriolis effect was first described in 1651 by Giovanni Battista Riccioli, and Italian scientist, it was not until 1835 when Gaspard-Gustave de Coriolis, a French mathematician, and scientist, first mathematically observed the Coriolis effect.

From his work in mathematical documentation, it became attainable or feasible to clearly describe and determine the Coriolis effect in the rotation of the Earth and the meteorological effects made by that rotation. A flow meter technology applies the very same mathematical principles by causing a vibration in the pipeline that a fluid traverses through.

The induced vibration along the pipes gives a rotating frame of reference that shows or demonstrates the Coriolis effect. Particular methods might differ, relying upon the design of the flow meter.

However, the adjustments in the vibration manifest the density of the fluid and the mass flow rate, which can be mathematically computed to provide a precise flow rate measurement and density. Due to the effectiveness and simplicity of the design, Coriolis flow meters are extremely accurate under any circumstances. A Coriolis meter can accommodate safe plant operating requirements and significant turndown.

Two-wire Technology

When the majority of the chemical plants, power generation stations, and refineries today were established, Coriolis meters weren’t ready for use in a two-wire layout. But thanks to technological advances, now, Coriolis meters can be a practical option.

For most plants that have used or utilized two-wire technology and are planning to retrofit, this is excellent news. Before, many facilities had to maximize what’s available in the market, which includes turbine meters, positive displacement, and differential pressure.

Each of these technology poses challenges with accuracy and reliability. What’s more, all of them have moving parts or components that require maintenance, can wear out, and cause unexpected shutdowns.

Historically, turbine flow meters have been undoubtedly affordable. However, when you add up the unscheduled and regular scheduled maintenance, as well as part replacement, revenue can be lost.

ROI Versus Capital Expense

Whatever project you are undertaking, from a retrofit or an upgrade to an entirely new facility, the cost is a chief factor in every step or stage of the process. Take a retrofit, for instance. An existing facility may have overhead cabling racks for about decades now.

Over time, more cables might have been introduced to replace or change the old ones. However, the old cables remain in place since the facility can’t afford to languish and stagnate during any removal work.

Take note that removing many cables would need significant manpower and time, even today. Thus, it is an expense no facility would want to undertake. But a more cost-effective and more straightforward solution is to change existing two-wire flow meters and use the cable again by introducing a Coriolis two-wire meter.

In this way, you don’t need to run piping for flow conditioning or add wiring expenses.

Takeaway

Having the best tools as much as possible for the job boosts efficiency and safety, and raises the bottom line. Also, it can smoothen the transition, since many experienced and skilled engineers retire, assuring those yearly goals are met.

Most of those retiring experienced technicians and engineers take with them years of experience on how to read a flow meter, work with the infrastructure, and how to troubleshoot. More often than not, they know the temporary fixes, workarounds, and shortcuts to keep a process running.

And the problem is that what they know is hard-won knowledge that can’t be taught in several days of training. Because of this, a retrofitting investment gains popularity today. Brand-new flow meters with modern diagnostic tools need less training and skills to be used by new hires.

What’s more, new flow meters notify the user about the possible problems that may arise and offer a solution. With the correct tools and equipment, employees will be positioned for success and minimize risks to the plant.
