Is Flow Meter Calibration Worth the Cost?

Is Flow Meter Calibration Worth the Cost? | Flowmetrics

Maintenance – what is it good for? Some companies invest the very least, or in some cases no time or funds at all in shutting down equipment for servicing. Other businesses have robust maintenance programs, making it part of their regular working schedule. Which is better? The following will discuss some of the reasons why flow meter calibration should be included in your operations.

 

For Long Life

 

Keeping equipment in excellent working order extends its life. When components are well-maintained, it saves your business money in the long run. The following are some of the industries that rely on flow meter calibration:

  • General Industry
  • Chemical and Petrochemical
  • Energy
  • Laboratory
  • Aerospace and Aviation
  • Pharmaceutical and Food

In each of the above sectors, well-made equipment and infrastructure can last many years beyond the manufacturer’s warranty, but because fabricated parts do not take care of themselves, they must be maintained.

 

To Promote Consistency

 

Each industry produces a product that consumers or businesses rely on. Take the energy industry as an example. Refineries and processing plants continuously produce a product that meets certain specifications. Flow meter calibration is one of the ways they can continue to provide a product of the same grade, octane or viscosity. Anything inconsistent in this industry can lead to machine failure or even dangerous outcomes.

 

To Meet Regulation

 

As you can tell from the industry list above, each field comes with its own set of regulations. The pharmaceutical sector is regulated by the FDA, and any failure to meet standards can result in consequences that end in significant profit losses and sometimes even a close of the business. There is no need to fear regulators if your operations are under compliance and in good working order.

 

For the Safety of All

 

Passenger airlines have gone out of business because of safety breaches, and bankruptcy is not even the big issue. Safety does not so much have to do with business as it does with lives. If a cargo plane goes down because of preventable equipment failure and a couple of lives are lost, it may not make as many headlines, but it is still unacceptable.

 

Why Let an Outside Firm Handle Calibration?

 

The best servicers do everything they can to prepare your flow meters for use in your facility. This usually means:

  • Testing and calibrating units under steady state flow
  • Using recognized standards and measurements rather than standards created “in house”
  • Controlling environmental factors such as temperature and pressure to match as closely as possible that of where the equipment normally operates

 

Outside firms perform rigorous inspections on units that can improve calibration results. They are capable of handling industrial cleaning such as removing mineral buildup or corrosion without damaging the equipment. If results still are not satisfactory, they can troubleshoot at a level that exceeds most persons outside of the calibration industry.

 

Maintenance can extend the life of flow meters, prevent unnecessary repairs, and improve safety, quality and consistency. A flow meter calibration company should be able to handle servicing for any brand of unit you may own. No matter the industry you work in, it is clear that keeping equipment in great working order is an investment that is worth every penny.

Maintenance for Optimum Bearing Performance

Maintenance for Optimum Bearing Performance | Flowmetrics

Bearings reduce friction between two moving surfaces, and from that job they wear down and eventually break. To best keep bearings rolling for as long as they can, some maintenance is required in various parts of the lifespan.

 

Before Installation

Bearings are shipped and stored with a thin layer of manufacturing oil to preserve the bearing. If this coating is wiped off, smudged through handling, or dries out the bearing can rust or the lubrication can become useless. While storing bearings make sure to keep the bearing coated with preservative oils.

 

During Installation

Bearings are designed to have an interference shaft fit on the shaft during application. This fit is built into the dimensions and is accounted for. If a bearing is installed onto a shaft too big or too small, the difference in clearance can wear the bearing much quicker than specified. 

Proper lubrication is necessary to reduce heat, and friction within the bearing itself. Due to the properties of lubricating oils, bearings may leak and can be sealed by silicone rings or sealing grease. 

 

Ongoing Maintenance

Through continuous use of bearings, lubricating greases and oils with wear out just as much as the interior rollers in the bearing. Properly replacing and refilling the lubricant of a bearing will extend the life of the bearing. Some manufacturers provide charts for re-greasing intervals, check with the OEM of your bearing for details.

VoicePrint Technology to Improve Network Security

VoicePrint Technology to Improve Network Security | Flowmetrics

Human voices are unique to the individual and current technology has been used to restrict access to authorized personnel using voices as authentication. Now by identifying the voices of devices on control networks a possible new defense would filter legitimate signals and attacks. 

“We have developed fingerprinting techniques that work together to protect various operations of the power grid to prevent or minimize spoofing of packets that could be injected to produce false data or false control commands into the system. This is the first technique that can passively fingerprint different devices that are part of critical infrastructure networks. We believe it can be used to significantly improve the security of the grid and other networks.” -Raheem Beyah Georgia Institute of Technology

The security techniques take advantage of the individual physical properties of each unique device. Security devices listening to the grid would differentiate devices that were authenticated to the grid, and identify illegitimate “noise” within the system. Furthermore, the system can use simple physics to flush out spoofing attempts. Depending on the physical configuration of breakers and valves, opening and closing procedures take a minimum amount of time. If a device gets a signal to open or close too soon after the last signal security staff would be notified of a possible attack.

 Because they also include devices with measurable physical properties, Beyah believes the approach could have broad application to securing industrial control systems used in manufacturing, oil and gas refining, wastewater treatment and other industries.

Flow Meters for Every Application

Flow Meters for Every Application | Flowmetrics

There are many flow meter variations out there, and each application requires a different style of meter. Depending on the fluid being measured each style of flow meter may be more suited to that situation. Everything from the viscosity to the potential contaminants plays a part in choosing the perfect flow meter for your needs.

Accuracy Coriolis flow meters are highly accurate, but may impinge the flow of fluids through the pipeline.

Consistency Nutating disk flow meters are simple to replace, but may need repeated calibrations as parts wear down.

Minimal Flow Restriction Electromagnetic flow meters do not block or reduce flow, but can be costly to maintain.

Miniature Burst Disks Problems

Miniature Burst Disks Problems | Flowmetrics

Rupture disks have been the go-to system for protecting vessels from over-pressurization. Miniaturization of these rupture disks has brought new setbacks in materials and designs. 

Burst disks are widely chosen over safety valves due to their quick response and evacuation of the vessel. These disks are produced to “fail” at a predetermined pressure difference between both faces of the disk. It is when they fail at that pressure that they protect the vessel from failing in a more disastrous manner.

As rupture disks are made smaller and smaller, low rated disks must use paper-thin metals easily broken during handling, assembly, and operation. It is recommended to use these disks when operation pressures are 75% or less of the rated burst pressure.

Chemical Processes to Change the World

Chemical Processes to Change the World | Flowmetrics

15% of the global energy consumption is spent on chemical processing. These processes aim at purifying certain substances out of mixtures, and the most common method is through heating and distillation. The vast majority of these purifying processes are done on crude oil to separate the various useful hydrocarbons. Alternatives exist for accomplishing this goal while using only 10% of the energy of distillation practices. Little research has been done to fully flesh out these alternatives, though.

Nuclear power is crucial for future generations, and crude oil is running out. Current estimates on the lifespan of our uranium reserves have them expiring within a century. To better fuel our need for energy well into the future, we will need to establish a cost-effective process to separate uranium from seawater. The amount of uranium in the oceans is roughly 0 times the amount we have left in our geological reserves.

Steam From Water Without Boiling

Steam From Water Without Boiling | Flowmetrics

Other projects have used plasmons to heat water, but this new test has increased the efficiency with “black gold.” A new material produced by the scientists uses gold particulates in a variety of sizes, a few “tens of billionths of a meter wide,” so small that the gold looks black. This mixture absorbs 99% of all visible and infrared light, and up to 90% of that light is converted to heat.

While the efficiency of this material is not record holding, carbon nanotubes are more efficient at converting light to heat, this material is much less expensive to produce and more readily applied to current uses of steam.
