SIL Level Switch Is Specifically Designed for Floating Roof Tanks

One of the most difficult and critical applications is measuring the high alarm or potential overfill condition on a floating roof tank containing liquid petroleum products such as crude oil or refined products such as fuel. It normally is comprised of a cylindrical steel tank equipped with an internal or external floating roof, that floats on the surface of the stored liquid. Floating roof tank systems are especially beneficial in eliminating the evaporative losses of the liquids. As opposed to a fixed roof tank there is no vapor space in the tank. This helps to reduce risk in highly explosive vapor environments. This is an extremely high cost of failure application, and one in which only the safest and most trusted products are accepted.

Safe operation of the tank farm relies on critical real time continuous level measurements of the liquids in the tank, as well as detecting when a high level condition exists. Products used in this application are typically required to meet the API 2350 Overfill Protection Standards, as well as SIL Safety Integrity Level performance standards to IEC 61508.

The challenges to reliably detect a high level condition on a floating roof tank are long sensor length requirements, and the variability of what is being measured. The floating roof may be dry in which case you need to detect the position of the physical metal roof. Or there may be a few inches of rain water or petroleum liquids on the roof. Measuring instruments need to determine very accurately, usually within a few millimeters, when the position of the floating roof has reached

The Drexelbrook SIL IntelliPoint capacitance probe level switch is specifically designed for Floating Roof Tanks (internal and external roofs) with a flexible brass level sensing probe. The level probe sensing element is field adjustable for lengths up to 15' (4.6 m). Electronics are designed to meet API 2350 Overfill Protection.

This level measurement system is specifically designed for spill prevention in floating roof tanks (internal and external roofs) using the IntelliPoint level switch with a flexible level sensing element for ease of installation (model 700-0005-595).

This level measurement system meets API 2350 regulations. It is ideal for use in safety related systems with requirements for functional safety for SIL2 in accordance to IEC61508-2, ed2, 2010 (Exida).

To prevent false alarms this level measurement system automatically recognizes and ignores coatings and is supplied with continuous self-test monitors circuits and sensing elements to detect faults.

A dual compartment housing separates the customer wiring from the sensing element and operating circuits. The encapsulated power supply/terminal block design eliminates the possibility of damage caused by moisture in the conduit.

The Floating Roof Tanks system comes with field adjustable lengths from 1' to 15' (0.3 to 4.6 m).

The system is based on our Manual Certify principle which allows the entire system to be manually tested without removing the sensor from the tank. The Manual Certify test checks that the Auto Verify circuits are operating and confirms the probe and cables are properly connected. Furthermore, the Manual Certify feature allows the electronics to sense changes in the probe that simulate contact with the media or floating roof. This provides the user with a method to ensure working performance without having to climb the tank.

No calibration or setpoint adjustments are required.

Key Features

• Loop or Line Powered
• Wetted Parts: 316SS 3/4" NPT Mounting, 3/16" FEP insulated flexible and adjustable cable, non-sparking brass sensor.
• Automatic and local or remote manual test functions ensure proper system operation.

High-performance and Resilient Seated Butterfly Valves for Commercial and Industrial Applications

A butterfly valve has a disc that is in the fluid flow path. In the most common style of butterfly valve, the disc revolves around a central axis, the stem, via a 90-degree arc from parallel to the flow direction (open) to perpendicular to the flow direction (closed).  Butterfly valves have a straightforward design with few moving components, making them simple to repair and maintain. The valve has four main parts: the body, the stem, the disk, and the seat. 

The butterfly disk is always in the flow path, but its thin profile has little effect on flow. Butterfly valves are popular because they provide tight shut-off, are available in various materials and sizes, and may be easily automated using a variety of quarter-turn electric and pneumatic actuators. 

You'll find butterfly valves in a wide range of industrial applications, from managing the flow of water to handling far more hazardous industrial fluids. Many industries use butterfly valves, including water treatment, chemical processing, pulp, paper manufacturing, food processing, power generation, etc. 

There are two primary classifications of butterfly valves:

1. High-performance butterfly valves (HPBV)
2. Resilient seated butterfly valves

 

High-performance butterfly valves include carbon or stainless steel bodies with Teflon seats and can withstand more significant pressures and temperatures.  Resilient seated valves usually feature ductile iron or aluminum bodies and operate at lower pressures and temperatures.

Butterfly valve bodies are available in two mounting styles: lug and wafer. Lug bodies include cast-in lugs with bolt hole designs that match pipe flanges. A wafer body valve does not have a mounting hole pattern, and mounting is facilitated by sandwiching the valve between two pipe flanges, with mounting bolts around the valve body. Wafer-style bodies are less costly. An advantage to lug body valves is their use as a dead-end valve, whereas wafer valves are unsuitable for this service.

The stem is a one or two-piece shaft that keeps the disk in place and provides the rotational torque that allows the disk to open and shut. The stem of resilient seated valves has protection from the process media by packing rings, allowing for a more cost-effective solution to regulate the valve's application to various potentially corrosive media. High-performance butterfly valve stems come into touch with process media and must be media suitable. 

The disk is the valve component that comes into direct contact with the process medium and regulates flow. Disks are available in various materials and optionally come with corrosion-resistant polymer coatings. Some butterfly valves include contoured disks that are carefully aligned with the stem to increase flow control, modify torque needs, or give the valve a longer life. 

A resilient seated valve closes via an "interference fit," which means the disk forces itself into the seat. The seat is the soft substance (polymer elastomer) including Buna-N and Nitrile, and should be specified depending on the process medium involved.

High-performance butterfly valves use an interference fit as well, but with significantly tighter tolerances, but also ensure tight seating with assistance from upstream pressure. PTFE or RTFE are the most often used materials for HPBV seats. Metal seats on HPBVs accommodate more significant pressure and temperature applications. 

Like other valves, butterfly valves have applications in which they outperform. To apply the optimum solution to your flow control applications, combine your process knowledge with your product knowledge with the application skills of a proven valve engineering professional.

Industrial Thermowell Process Connection Types

This video covers the common types of thermowell process connections. The styles are referred to by what their process connection is.

The types are threaded thermowell, a flanged thermowell, a welded or weld-in thermowell, and a sanitary thermowell.

Threaded thermowells are commonly used when thermowell removal occurs infrequently. These wells are typically threaded into a welded fitting widely referred to as a weldolet on the pipe or vessel. Typical installations include smaller pipes or vessels where corrosion is not an issue.

Flanged thermowells are the preferred well for applications that require frequent removal or replacement due to corrosion or other hazards. Flanged wells will bolt to a mating flange installed on the process piping. Typical installations include large pipes with high pressure and high corrosion.

Weld-in thermowells are welded directly to the pipe or tank and provide a high-quality connection. Because being welded in, their removal is not easy, and they should only be installed when quick access is not required, and corrosion is not an issue. Typical installations include very high temperature and high-pressure applications, for example, a steam line or other non-corrosive applications.

Sanitary thermowells are generally fitted with a Tri-clamp or other clean-in-place connection. These thermowells also have a smooth surface which allows for easy cleaning and prevents contamination of the process: typical installations include dairy, food processing, and pharmaceutical industries.

Water Cut Meters from Drexelbrook

The water cut is the proportion of water collected in a well to the total liquids produced. As crude oil and hydrocarbons travel through a pipeline, a water cut meter monitors the amount of water (cut). BS&W is the amount of non-hydrocarbon contaminants, dirt (sediment), and water included in a crude oil shipment. The lower the BS&W, the better.  Water content determination and BSW have been a persistent and long-standing issue for the oil and gas industry.

Water cut meters measure the water cut (or BS&W) of oil flowing from a well,  a separator, crude oil transfer in pipelines, and tanker loading. 

Drexelbrook has been the global leader in capacitive-based water cut measuring. Drexelbrook has the industry's highest pressure and temperature ratings, and their capacitive probes can withstand pressures of up to 1500 psi and temperatures of up to 450°F. 

The Universal IV CM Series from Drexelbrook is a high-quality water cut meter with a range of 0-50 percent in light oil and 0-80 percent in heavy oil. 

The Universal IV CM Series builds upon Drexelbrook's expertise in RF Admittance, which enables the electronics to disregard paraffin and other coatings that accumulate on the probe. 

The Universal IV CM has a one-of-a-kind Cote Shield built into the Universal IV CM series and allows the instrument to disregard a pre-determined length of the sensing element. It contains a Perm-A-Seal sensing device that eliminates the need for epoxy coatings, which wear out and need costly maintenance. 

Field setup is available anywhere along the two-wire loop when using this water cut meter with Drexelbrook's HRTWin or the STExplorer PC program. 

Choose the Universal IV CM sensing element depending on pipe size, wetted portions, NACE requirements, and pressure/temperature requirements. Drexelbrook has a broad assortment of probes to suit almost any purpose. 

All water cut meters have a built-in LCD and keypad, are pre-calibrated at the manufacturer, and need just one point confirmation. 

The Universal IV CM water cut meter is intrinsically safe and approved for Class I, Division 1, and Zone 0 hazardous areas.

HABONIM 50 Series Top Entry Cryogenic Ball Valves

Due to its unique one-piece body structure, the HABONIM Series 50 Top Entry Valve is the ultimate answer for pipeline integrity on the one hand and inline serviceability on the other. 

The 50 Series of HABONIM bidirectional top entry cryogenic ball valves are a modern adaption of a trunnion ball valve with top entry construction and patent-pending new design elements. 

The main challenge for an assembly or maintenance team with a standard top entry valve is usually the complexity of assembly and disassembly of the valve inner parts, the time-consuming operation, and the requirement for special equipment and jigs. 

All of these problems are addressed and solved by HABONIM's Series 50 top entry valve design. 

Upon removing the valve bonnet screws, the crew has immediate access to the valve's interior parts, allowing for thorough maintenance and replacement of all inner components and sealing. This one-of-a-kind design provides for complete valve renovation inline without the need to remove any insulation pieces.

One Double Piston Effect (DPE) dynamic seat is used in the patent-pending design, allowing bidirectional sealing under the full differential and a relatively simple design with few parts and no closed cavities. These qualities provide all of the advantages of a ball valve's high flow (Cv) with no restriction on flow direction or sealing, as well as a safer cryogenic construction. 

When installed, a patent-pending supplementary optional body extender raises the valve's bonnet above piping insulation, allowing the valve to be maintained without removing the insulation or without special valve insulation boxes. 

The valve's revolutionary design allows for quick inline serviceability with minimal effort and inexpensive equipment for valve dismantling, replacement, and reassembly.

Food Industry Batch Level Control

Many food processing facilities employ batch processes in their production facilities where the operator starts with an empty vessel and create the final product by adding multiple ingredients.

The batch process requires the operator to know the amount of each ingredient added to the blending vessel. Point-level controls speed the process by establishing setpoints at each ingredient fill point,  often accomplished with several level sensors, each detecting one ingredient.

Batch food processing applications are challenging. The sensor must include sanitary fittings and CIP (Cleaned In Place) design. In many cases, the ingredients and final products are dense and sticky, wreaking havoc on some technologies such as mechanical switches and tuning forks. Products in the blending vessel may be thick and could cause damage to fragile sensors. Finally, many batch processes are agitated, causing false tripping due to splashing material. 

As you can tell, proper level sensing technology is critical. Choosing the wrong technology will cause ruined batches, costly downtime, and the possibility of overfilling.

The Drexelbrook Multipoint II offers the best solution for batch process control applications in the food industry.

Drexelbrook, a leading manufacturer of level controls, recommends its RF Admittance Multipoint II. It provides a total solution for the batch processing of food. The RF Admittance Multipoint II is a single sensing element and a single mounting point from the top of the vessel using a sanitary Tri-Clamp fitting and has no moving parts to wear out or get hung up. The Multipoint II sensor is a 3A sanitary designed steel rod with Kynar or TFE insulation developed for CIP procedures. RF Admittance Cote-Shield driven shield circuitry ignores heavy coatings on the sensing element, preventing false alarms. The Multipoint II consists of three independent DPDT relays, and control points are set anywhere along the vertical sensing element.

Drexelbrook Multipoint II Advantages:

• 3A designed sanitary sensing elements
• No moving parts
• 3 control points on one vertical sensing element
• Cote-Shield circuitry eliminates false alarms due to coatings
• Designed to endure Clean In Place (CIP) demands

All Stainless Steel Ball Valve and Actuator Systems

Ball valves control flow by rotating a spherical ball within the valve, which contains an opening or port, through which liquid can flow when turned to align with the flow direction. When the ball rotates 90 degrees, the port becomes perpendicular to the flow direction, preventing fluid from passing through the valve. Stainless steel construction is advantageous in a flow control ball valve because it is highly corrosion and contaminant resistant, requiring less cleaning and maintenance and often providing a longer service life. 

Stainless steel pneumatic actuators are available in spring return, double acting, fail open, and fail close configurations. A corrosion resistance surface - resistance to most corrosive materials - is one of the advantages of using a stainless steel actuator. The stainless steel pneumatic actuator is excellent for heavy-duty automation, especially in corrosive environments. Stainless steel actuators with a durable stainless steel body manufactured to NAMUR standards continue to perform in the harshest environments. 

Piping Specialties' stainless steel actuated ball valves provide exceptional accuracy and dependability in flow control and open/close operations, critical in manufacturing, chemical, oil & gas, wastewater, processing, and other applications. 

Piping Specialties is committed to providing the most suitable valve for your application. For more information about stainless steel valves, call 800-223-1468 or visit https://psi-team.com.

The REOTEMP Model W Explosion Proof, Field Mounted, HART Temperature Transmitter

Process control instrumentation monitors and controls a process to maintain proper functioning standards and keep it within a proper functioning and safe operating range. Process variables are the parameters or quantities maintained to keep the process within desired and acceptable limits. Instrumentation systems compare process variables to a desired setpoint and then produce offsetting and corrective control outputs. 

Typical process variables are level, flow, temperature, density, pH (acidity or alkalinity), mass, and conductivity. 

Temperature is a measurement of how hot or cold something is, whether it's an object or a process medium. The temperature setpoint is the process variable's target value for optimum control, quality, and safety. In a process where the temperature stays within plus or minus 1 degree Celsius of 100℃, the setpoint is 100. 

Temperature transmitters are instruments that convert a weak thermocouple or RTD signal to a robust analog (4-20mA or HART) or digital (Profibus or Fieldbus) signal. The temperature sensor and the final control device communicate through the transmitter. Since transmitters provide more robust analog or digital outputs, external signal conditioning and amplification devices are eliminated, thus lowering costs.

The REOTEMP Model W Explosion Proof Field Mounted HART Temperature Transmitter includes a local display, HART compatibility, and a 4-20mA output. The field-mounted transmitter is available as a complete RTD or thermocouple assembly customized to your process. 

The REOTEMP Model W includes linearized temperature measurement with TC and RTD sensors (Pt100 and Ni100) inputs, local display, HART communication, and 4-20 mA analog PV output for individual, difference, or average temperature measurement. It can handle two RTD or TC input sensors, and up to 63 transmitters (HART 7) can connect in a multidrop communication setup.

The COMPACT Quarter-turn Rack and Pinion Pneumatic Actuator

The Habonim COMPACT actuator is a quarter-turn rack and pinion pneumatic actuator that doubles the torque of conventional pneumatic actuators. Habonim's patented four piston design, which generates torque around a centrally located piston, is responsible for superior performance, translating to double the power for the same size actuator or half the size for the same power. 

The COMPACT has four small cylinders, one on each of the cube's four sides. The smaller pinion and minimized travel distance of the pistons in the COMPACT require less air pressure to produce the same torque output as a larger double piston actuator. As a result, there's a reduction in emergency shutdown response, air consumption during operation, and maintenance.  Habonim's unique quarter-turn COMPACT actuators have the superior performance of twice the torque per size, much longer cycling before any care, high opening and closing speed, and exceptional durability in the most demanding industrial environments. 

STANDARD ACTUATOR FEATURES

NAMUR & ISO interface

A wide range of accessories such as solenoids, positioners, and limit switches are available for direct mounting to the COMPACT actuator, and any accessory with ISO 5211 and VDI/VDE 3845 (NAMUR) will mount to the actuator. 

NAMUR VDI/VDE 3845

This standard specifies various accessories with VDI/VDE interfaces, such as limit switches, pucks, indicators, and positioners, with simple mounting onto the actuator top face. 

NAMUR solenoid mounting

One of the four actuator covers available includes a pad for solenoid mounting per the NAMUR international standard. Any solenoid that conforms to the NAMUR interface can be directly mounted to the actuators, simplifying solenoid installation and eliminating the need for additional piping. Because the pressurized air supply is available at the port entrance, it also allows for quick actuation response. 

ISO 5211

The actuator bottom flange conforms to the ISO 5211 international standard and includes a star-shaped female drive to accommodate a wide range of valve output shafts. The valve can be attached to the actuator with a bracket or mounted directly onto the actuator using one of the ISO hole patterns.

COMPACT actuators are part of control packages in various industries and providing superior performance in the cycle times, size, weight, compressed-air consumption, and reliability in high cyclic applications.

Replace Inaccurate and High Maintenance Displacer Level Controls With RF Admittance Technology

 Cost Effective Alternative to Displacer Level Measurements

THE PROBLEM

• Displacer accuracy is dependent on the specific gravity of a fluid. Varying specific gravities and “off spec” product result in significant measurement errors.
• Coating build-up on the displacer body produces errors.
• “Blowdowns” to clean displacer internals and cages is time consuming and expensive.
• Rebuilds due to component wear add significantly to the total cost of ownership.
• Interface measurements are more sensitive to slight specific gravity variances and result in separator throughput lower than the design specification.

THE SOLUTION

• AMETEK Drexelbrook Radio Frequency (RF) Admittance technology eliminates all of the inherent problems with Displacer technology level measurement.
• RF is immune to changes in specific gravity, density, temperature, and pressure.
• Accuracies to 1⁄4 inch of level in short span installations.
• No moving parts to wear, No periodic maintenance.
• Replacement cost differentials covered by eliminating one rebuild.

The Azbil AX24R Reduced Bore Vortex Flowmeter

EXTENDED MEASURING RANGE FOR LOWER FLOW RATES

Much of the measuring range of a standard vortex flowmeter is at higher fluid velocities. Because of this, measurements at low flow conditions may be missed due to the low flow cutoff. To remedy this issue, users often install pipe reducers and a smaller than line size vortex meter to increase fluid velocities through the meter. The Azbil AX24R reduced bore vortex flowmeter has integrated reducing flanges, eliminating the need for separate pipe reducers and spool pieces. This integrated reduction extends the measuring range to capture lower flow rates.

CAPTURES STEAM FLOW IN BOTH HIGH AND LOW DEMAND SEASONS

Steam usage in heating systems can vary widely based on seasonal demands. These systems are commonly sized with the high demand season (colder weather) in mind, and little thought is given to the low demand season (warmer weather). This leads to a situation where steam flowmeters are oversized and may miss flow measurements at low flow conditions. AX24R reduced bore vortex flowmeters have an extended low flow measuring range, capturing both high and low demand seasons.

REDUCED INSTALLATION COSTS

Like most flowmeters, vortex flowmeters have requirements for unobstructed upstream and downstream piping lengths to ensure a proper flow profile through the meter. Adding pipe reducers adds cost and complexity to the piping design since those unobstructed piping lengths are required before and after the pipe reducers.

The AX24R reduced bore vortex flowmeter has integrated reducing flanges, eliminating the need for separate pipe reducers and spool pieces. Drastically reducing both the complexity and cost of the meter installation.

SAME FACE-TO-FACE DIMENSION AS A STANDARD VORTEX METER

AX24R reduced bore vortex flowmeters have the same face-to-face dimension as a standard AX24 flowmeter for pressure classes up to ANSI 600. So if process conditions change, the meter body size can be changed without any costly piping modifications. This is especially useful in project planning, as it allows for flexibility into the future.
