FLUXUS G721 ST
FLUXUS G721 ST

With FLUXUS ST, for the first time ever, it is possible to capture all steam usage from very low to very high flow rates with one meter size. The acoustic measuring method proves to be impressive with its exceptionally high measuring dynamics, is highly sensitive even at very low flow velocities and functions independently of the flow direction. Due to this large flow range (flow velocities from 0.003 ft/s up to 200 ft/s, there is no need to reduce pipe diameter to fit an inline meter’s requirement of minimum flow velocity. Moreover, the non-invasive measurement does not cause any pressure loss. The transducer mountings can be completely insulated to reduce any heat loss to the environment.

Thermal Mass Flow Meters for Oil & Gas Applications

Thermal Mass Flow Meters for Oil & Gas Applications
Beyond traditional oil and gas extraction techniques, the Oil & Gas Industry has been booming in the United States and around the world since the demand for shale oil has led to horizontal fraction drilling all over the world and even in several regions of the U.S. This drilling is happening both on and offshore to tap into vast quantities of resources trapped in the porous shale deposits deep underground and under the seabed. The flowback from shale oil plays has many different components that must undergo a process of separation in order to isolate the resources for use. Once separated, the byproducts are often stored in tanks before being transported for distribution and sale.

Thermal mass flow meters have been used to measure tank vent and flash gas during storage. VOC emissions from these tank batteries are required to be reported for regulatory purposes. The accurate monitoring of leaks from these tanks is another common use of thermal mass flow meters.

Thermal Mass Flow Meters

The flowback from fracking well heads must go through separators in order to separate the
water/chemical solution from the oil and gas components that the water has forced out of the shale formations. The gases processed by the separators exit the separator unit from its own outlet that must be accurately measured for accounting and allocation purposes. Furthermore, flow of water, oil, and gases from the separator equipment must be measured to determine how productive the resources from the gas well head are. Over time, the well heads produce less and less gases and owners must determine when to decommission them.

Due to the often remote locations of these gas wells, there are not always local utilities available to power the equipment needed at the well site. Fuel gas to the equipment is needed to measure and monitor consumption.

Exhaust and vent gas from compressor packing cases is required to be monitored for environmental impact.

Some common gases and applications:
  • Compressor Packing Case Exhaust Flow Measurement
  • Greenhouse Gas Emissions Monitoring Flow Meters
  • Continuous Emissions Monitoring
  • Flow Meters for EPA and Other Emissions Regulations and Protocols
  • GHG Flow Meter
  • Sub meters for Natural Gas Measurement
  • Tank Vent / Flash Gas Station Monitoring
  • Natural Gas Totalizers
  • Methane Flow Measurement
  • Propane Flow Measurement
  • 40 CFR Part 60 Subpart OOOO Reporting

Basics of Rotameters

Rotameter operationRotameters, also referred to as variable area flow meters, have diverse industrial processing applications that range from simple to sophisticated. The devices are easy to install, require no electrical connection, and provide direct flow rate reading. They provide fail-safe flow rate readings in a wide array of industrial applications.

Rotameters: An Overview 

Developed by German inventor Karl Kueppers in 1908, Rotameters measure the volumetric flow rate of liquids and gases.

Important elements of a rotameter (variable area flow meter) include the tube and the float. Their operation is simple. The tube is fixed vertically and the fluid is fed from the bottom. It travels upward and exits from the top. The float remains at the bottom when no liquid is present and rises upward when fluid enters the tube.

The float inside the tube moves in proportion to the rate of fluid flow and the area between the tube wall and the float. When the float moves upward, the area increases while the differential pressure decreases. A stable position is reached when the upward force exerted by the fluid is equal to the weight of the float. A scale mounted on the tube records the flow rate of the liquid. Usually, the flow can be adjusted manually using a built-in valve.

Types of Rotameter 

Variable area flow meters can be categorized by the type of tube they use, which relates to their ability to withstands various pressures, temperatures, process media, and cost. Process connection size and wetted part materials vary as a function the rotameter type and construction.

Glass Tube Rotameter
Glass Tube Rotameter
(Yokogawa)
Glass Tube Rotameter - The basic glass variable area flow meter consists of borosilicate glass tube while the float is made of either glass, plastic, or stainless steel. The most common combination is a glass tube and metal float. This is suitable for a measure the flow rate of liquid of low to medium temperatures and pressures.

Applications:

  • Analytical instrumentation
  • Industrial processes
  • Chemical production
  • Pharmaceutical production
  • Oil & gas extraction
  • Refining processes
  • Fuel cell research
  • Water treatment systems

Metal Tube Rotameter
Metal Tube Rotameter
(Yokogawa)
Metal Tube Rotameter - Metal tube variable area flow meters are another type that is suitable for temperatures and pressures beyond the physical and mechanical limits of glass tube versions. They are generally manufactured of stainless steel, aluminum, or brass. The piston position is determined by the mechanical and magnetic followers that can be read from the outside of the tube. They are suitable in situations where applications conditions would damage the glass metering tubes, such as steam applications.

Applications:

  • Purge liquid/ gas metering
  • Liquid, oil, or gas flow measurement
  • Chemical injection
  • Rotating equipment flow measurement
  • High-pressure flow meters on offshore oil platforms

Globe Control Valves

Globe Control Valves
Internal view of globe control valve (Masoneilan)
Globe control valves work differently when compared to gate valves, ball valves, butterfly valves and plug valves in process control applications. They are primarily used to control the flow inside pipes, and are popular in a wide variety of industries. Globe control valves are ideal in situations where precise control is required. They are used to regulate flow in pipelines with a high degree of accuracy by regulating a pressures drop created in the valve body that allows the fluid to pass through the passageway (port) in the valve body. The control valve stem provides linear motion to bi-directionally control flow, opening and closing the valve by changing the distance between valve disc and seat. The flow in the pipeline changes according to the position of the disc lifting from the seat. The movement is controlled through the use of manual operators, or through the use of electric or pneumatic actuators.

Applications of Globe Control Valves 

Globe control valves are used in many different industries, but particularly in the petrochemical and power generation industries on fuel oil pipes, chemical feed systems, steam pipes, as well as cooling water and feedwater systems.  Other industrial applications of globe valve include boiler, main steam vents, and turbine lube oil systems.

Pros

Globe control valves have many advantages that make them preferable over other valve designs. Globe control valves have excellent shut-off and throttling capabilities. In addition, globe valves are easy to maintain and repair compared to other valves.

Cons

Globe control valves have also certain shortcomings. For instance, globe valves have an S-shaped flow pattern (as opposed to a straight-through flow pattern) which creates a significant pressure drop making them unsuitable for applications constant pressure is required.  Another shortcoming of the globe valves is they generally require greater torque to open and close, requiring larger actuators to properly seat the valve.

Clamp-on Ultrasonic Flow Measurement of Natural and Process Gases


FLEXIM‘s ultrasonic gas flow meters use the proven clamp-on transit-time correlation technique also employed for the F series liquid meters. Special ultrasonic transducers are simply clamped onto the outside of the pipe and never come in contact with the gas.

FLUXUS® G represents the ideal solution for non-invasive gas flow measurement. FLEXIM’s non-invasive technology is an advantageous and cost-effective alternative to conventional methods, particularly with chemically aggressive, poisonous or high pressure media. With their extremely wide turn-down ratios, the instruments of the FLUXUS® G series register even the smallest flows.

Non-invasive Measurement

  • No contact with the medium, therefore no possibility of chemical attack. No need for expensive special materials (sour gas applications for example)
  • No wear and tear, even with high flow velocities or with gas containing particles
  • No clogging of small bore impulse lines with deposits, condensate, inhibitors, oil vapors, dust (as happens when using impulse lines in the measuring system)
  • Insensitive to dust and humidity

Plant-wide Condition Monitoring

In addition to the most important assets found in industrial facilities, there are often a host of “supporting” assets that make up the balance of the plant such as pumps, motors, blowers, heat exchangers, fans, and others. This auxiliary or plant-wide equipment may be spared or sacrificed, and its impact on the process stream may vary from moderate to minor. Regardless, such machines—just like their more highly important counterparts—can benefit from Condition Monitoring. Condition Monitoring provides affordable, effective portable and permanent condition monitoring solutions that are delivering tangible benefits for tens of thousands of customers around the globe.

Financial Justification

For many assets, failure can mean substantial or total loss of production, often worth millions per day. Or it can lead to the release of hazardous substances, fires, and even explosions— resulting in a severe safety hazard as well as fines for violating environmental regulations.

Maintenance Costs

When viewed on a per-asset basis, maintenance costs for plant-wide assets can appear modest. However, when viewed collectively across the dozens, hundreds, or even thousands of assets in a typical plant, these costs can be appreciable. Reducing the maintenance costs on each asset through effective condition monitoring—even by a mere 10%—has a large impact on plant profitability. Condition Monitoring is a planning tool that allows more effective insight in planning and asset management, allowing maintenance to be done in advance of a functional failure.

Things to think about as you move towards Predictive Maintenance:
  • 90% of failures are NOT time-based.
  • 50% of companies site maintenance and reliability as a top priority.
  • It costs 6x as much for unplanned events vs. planned maintenance in process industries.
  • A 60% estimated increase in environmental, health and safety spending among global exploration & production companies.
  • 50% of workforce to retire in the next 5 to 10 years. Knowledge & experience is not being transferred.
Potential impact of a conditioning monitoring program and the move towards Predictive Maintenance:
  • -70% Machinery breakdowns 
  • -40% Plant downtime
  • -50% Maintenance costs
  • +25% Production

Pneumatic Actuator Types

Pneumatic valve actuators all provide the same function:  They convert air pressure to rotational movement and are designed to open, close, or position a quarter-turn valve.  These include ball valves, plug valves, butterfly valves, or other types of 90 degree rotational valves.

The basic design variations of pneumatic valve actuators are as follows:

  • Scotch-yoke
  • Rack and pinion
  • Rotary vane

Let's review each of these in detail:

Scotch-yoke Actuators

Scotch-yoke ActuatorThese actuators come in a multitude of sizes, but are usually used on larger valves because they can produce a very high torque output.  They employ a pneumatic piston mechanism to transfer movement to a linear push rod.  That rod, in turn, engages a pivoting lever arm to provide rotation. Spring return units have a large return spring module mounted on the opposite end of the piston mechanism working directly against the pressurized cylinder.




Rack & Pinion Actuators

Rack & Pinion Actuator
These actuators are sometimes referred to as, “lunch box,” because they, well, look like a lunch box. This actuator uses opposing pistons with integral gears to engage a pinion gear shaft to produce rotation. They are usually more compressed than a scotch yoke, have standardized mounting patterns, and produce output torques suitable for small-to-medium sized valves.  Rack and pinion nearly always include standard bolting and coupling patterns to directly attach a valve, solenoid, limit switch or positioner.  One of their features include several smaller coil springs mounted internally, which provide the torque to return the valve to its starting position.


Rotary Vane Actuators

Rotary Vane Actuator
These actuators are usually used when the application requires a significant space savings.  They take up less space when comparing size-to-torque with rack and pinion and scotch yoke. Rotary van actuators also benefit from a reputation of longevity.  They contain fewer moving parts than other types of pneumatic valve actuators.  Rotary vane actuators use externally mounted, helically wound "clock springs" for their spring return mechanism.

When considering the choice of pneumatic valve actuators, your decision comes down to size, power, torque curve and the ease of adding peripherals. To ensure that your valve actuation package will be optimized for safety, longevity, and performance, the advice of a qualified valve automation expert should be sought out. That expert will be able to help you with the best selection of the appropriate valve actuator for any quarter turn valve application.

The VEGA MINITRAC 31 Radiation-based Density, Level, and Flow Measurement Sensor


Radiation is a popular means of density measurement in several industries, including refining and offshore oil and gas.  The VEGA MINITRAC 31 is suitable for liquid and bulk solids applications in vessels that present mechanically difficult process conditions. The measured value is detected non-intrusively, right through the vessel wall. Process fittings and vessel openings are not required. The instrument is therefore ideal for retro-fit applications. The VEGA MINITRAC 31 can be used for many different measuring tasks. Apart from density measurement and level detection, the MINITRAC 31 can also detect residues and the mass flow rate when used in conjunction with a flow meter. This video demonstrates how the sensor uses radiation to reliably and accurately measure the density of liquids and slurries and how operators can use Bluetooth-enhanced display modules for wireless remote access to density sensors.

Industrial Flow Meter Selection

Industrial Flow Meter Selection
Flow meter selection chart. Click on image for larger view.

Many industrial process control operations require fluid flow measurement as an essential element in the design of the process. The proper application and installation of a flow meter as part of the fluid transfer system will provide accurate flow measurement.

Industrial flow meters use different technologies to measure fluid flow rates directly or indirectly. Some of the most common technologies for fluid flow measurement are vortex flow meters, magnetic flow meters, Coriolis flow meters and rotameters.

Each separate technology has attributes that can make it more suitable for certain applications. The selection of the most appropriate flow measurement technology for an application is an initial and crucial step in the design of a functioning fluid measurement system.

Selection criteria such as fluid temperature, pressure and velocity will be included in the selection process. Further considerations include whether the fluid may be abrasive, corrosive, clean or dirty. The state of the fluid, liquid or gas, must also be taken into account.

The table above provides general guidance on which technologies to consider, based on the above mentioned factors. This will help you to focus further research on product selection.

Contact Classic Controls with any industrial flow application you may have. Their application engineers will provide guidance and advice to assure the proper flow meter is chosen.

Magnetic Level Indicators (MLIs) and Bridle Combination Units

Magnetic level indicators
Magnetic level indicators provide highly visible indication of level with or without signal outputs monitoring tail and vessel level. The term bridle is used to describe a vertical pipe connected to the side of a storage tank or process vessel, most often with side-to-side or side-to-bottom connections. Because the fluid inside the bridle rises and falls equally with the level of fluid inside the tank or vessel, bridles have been adapted for level measurement use on a broad scale.
Magnetic level indicators

Below is a good instructional reference document (courtesy of VEGA) on how magnetic level indicators (MLIs) are installed and how they work.
