Industrial Process and Commercial Pressure Gauge Selection

Industrial Process and Commercial Pressure Gauges

Download the US Gauge Product Selection Guide from this link.

Pressure gauges are ubiquitous in practically all industries on machines all around the world. At the same time, there are millions of different combinations of shapes, sizes, options, and materials. It's imperative to follow these five application factors for safe use and extended product life.

Process Media

Because direct contact of the sensing element to the process media is possible, any caustic media, particle media, or media that can harden and clog the pressure gauge element, must be avoided. Using a direct connection and Bourdon tube sensor is satisfactory for a non-clogging, non-corrosive medium. Use a diaphragm seal for process media that could cause blockage or be corrosive.

Temperature of the Process Media

Very hot media, such as steam or hot water, can raise the internal temperature of the gauge, resulting in failure or a dangerous state. For high-temperature applications, use a gauge "siphon" or diaphragm seal.

Environment and Ambient Operating Temperature

It is critical to understand the rated ambient environment for any instrument. Elevated ambient temperatures, dampness, vibration, and corrosive environments can all impact accuracy, calibration, and safety. If oxidizing or reducing atmospheres exist, select the appropriate case and mechanism materials, and consider installing supplementary devices, such as remote diaphragm seals, to move the gauge.

The Potential for Severe Pressure Fluctuations

The addition of pressure restrictors, snubbers, or liquid-filling will increase the service life of the pressure gauge in applications where dramatic line pulsations or high over-pressure conditions are possible.

Installation Orientation and Connection Type

Bottom (radial) and rear connectors are standard on pressure gauges. NPT (National Pipe Thread Taper) threaded connections are the most common. However, numerous different process connections are available, including straight threads, metric threads, and specialized fittings. Make sure you understand how the gauge is connected. Pressure gauges should almost always be upright when installed.

Piping Specialties / PSI Controls is standing by, ready to help you apply the correct pressure gauge for your application. Call us at 800-223-1468 for more information on pressure gauges.

Kurz Flow Meter Allows Precise, Real-Time Dry Flow Measurements for Landfill Pollution Reporting

Kurz Flow Meter

Landfill gas (LFG) is a natural byproduct of organic material decomposition in landfills. LFG is approximately half methane (natural gas's primary component), half carbon dioxide (CO2), and a small amount of non-methane organic compounds. Methane is a potent greenhouse gas that traps heat in the atmosphere 28 to 36 times more effectively than CO2 over a 100-year cycle.

Landfills for municipal solid waste (MSW) are the third-largest source of human-related methane pollution in the United States, accounting for around 15.1 percent of total emissions in 2018.

LFG can be captured, transformed, and used as a renewable energy resource instead of escaping into the air. Using LFG reduces odors and other risks associated with LFG emissions and methane migration into the atmosphere, which contributes to local smog and global climate change. 

A collection of wells and a blower/flare (or vacuum) device remove LFG from landfills. The collected gas moves to a central location where it can be stored and handled, depending on the gas's ultimate use. The gas can be flared or put to good use in an LFG energy project from here.

Because of regulatory requirements, numerous landfills install gas control controls. The federal government has adopted legislation that regulates the use and upkeep of landfills. These rules help eliminate ozone precursors (volatile organic compounds and nitrogen oxides), methane, NMOCs, and odorous compounds in landfill gas pollution, which harms human health and the environment.

Thermal flow meter technology is known for having a low-pressure drop and is suitable for calculating extremely low flows. On the other hand, standard thermal flow meters do not operate well in condensing gas environments like landfill methane recovery systems. The accuracy issues associated with wet gas flow measurements grow by the unpredictability of moisture levels caused by leachate, rain, temperature, and humidity. 

The Kurz WGF flow meter is perfect for use in wet gas applications. Kurz allows you to quantify gas flow precisely and provide real-time dry flow measurements for pollution reporting (federal, state, local regulations, greenhouse gases, and the Landfill Methane Rule).

Reduced Bore Vortex Flowmeter Provides Better Measurement for Low Flow and Also Saves Cost

Reduced Bore Vortex Flowmeter

Azbil’s AX24 Multivariable Vortex Flowmeter offers accurate and reliable flow metering in a multivariable design. The multivariable design incorporates a high-accuracy velocity sensor, a precision platinum RTD temperature sensor, and a solid-state pressure transducer. The meter’s process connections match the line size but use integrated reducing flanges, and the meter body reduces in diameter, increasing the fluid velocity through the meter. Increasing the velocity in this fashion extends the meter’s measuring range to capture lower flow rates that a full line size meter might miss.

Industrial Refractometers

Industrial Refractometers

Refractometry, a mixture of physics, material science, and chemistry, is a method that calculates the composition of known substances by measuring their respective refractive index (RI). The refractometer determines dissolved solids' concentration by making an optical measurement of a solution's refractive index (nD). The refractometer measures the refractive index nD and the temperature of the process medium. The calculation is based on the refraction of light in the process medium, called the critical angle of refraction, using a yellow LED light source with the same wavelength (580 nm) as the sodium D line (thus nD). In most solutions, the concentration of solute in a solvent can be determined by measuring the refractive index nD. The relation between the refractive index and the concentration depends on the solvent and solute, temperature, and wavelength.


Typical examples of industrial refractometry uses are:


  • The calculation of the salinity of water to assess its drinkability.
  • The analysis of dissolved solids in liquor production in pulp and paper production.
  • The assessment of sugar content ratios for food products and beverages.
  • The understanding of the hydrocarbon content of motor fuels. 


These are just a few examples. There are many more common industrial uses for industrial inline refractometers and thousands of unidentified potential applications.

Level Measurement for Water in Sewage Pools

Level Measurement for Water in Sewage Pools

This application takes place at a large power plant well known for its "Green Approach" and it's commitment to ensuring a clean and healthy atmosphere in and around the plant. 

The branched sewer system of the power plant requires instant maintenance and control. The plant uses water to operate the turbine. This water and other wastes move to the city’s wastewater treatment plant through the sewage system.

Some of the sewers are dispersed in remote locations around the plant, making it difficult for personal maintenance personnel to approach and repair damage on time. Plant technicians were looking for a solution to control the sewers better and avoid cases where wastewater might overflow. 

The sewage pool readings had to be transmitted to the central DCS because the sewage system connects to a central control room. The plant needed a 24/7 watch and an on-site guard to gain maximum control over those sewers. 

Technicians also stressed that wastewater flooding was inevitable because it takes time for the equipment to handle blockages. This flooding has caused severe damage to the environment. It was essential to control the wastewater level in the sewers to avoid cases such as these from reappearing. 

The Drexelbrook Usonic - The Solution 

After a lengthy examination of several possibilities, the plant decided to install two Drexelbrook USonic systems in its sewage pools. The ability of USonic to produce non-contact, continuous, and accurate readings of the water level in the pools gave the engineers of the plant a clear picture of the pools' status. 

Its compact size and integral construction simplify its installation, offering an efficient solution in no time at all. The USonic had no problem providing 12ft water level readings with a measurement range of up to 30 ft.  It can map obstacles in the pool and memorize interfering signals with its scan distance function. 

The USonic was linked to the central control system via 4-20mA, allowing the plant engineers to control the water level in the sewers constantly. The engineers know that the sewers would maintain the correct water level, and the system would be alerted in an emergency. 

Summary

The two USonic systems installed in the power plant give complete control over the sewers' water level to the plant's engineers. The systems' ability to display continuous level readings around the clock improved maintenance crews handle the sewage system.

To detect sudden blockages and avoid environmental damage on time, they can now save time. The plant received an immediate return on investment due to its compact size and reduced price.

The Flow Safe F9000 "SurgeFlow" Liquid Surge Relief Valve

Liquid product pipelines must be protected from liquid surges. Surges are caused by pump failure, rapid block valve closing, non-return check valve hard-shutting, emergency shutdown of a tank or loading system, or even a pump coming on or tripping. The magnitude of surge pressures varies, some virtually undetectable to those severe enough to cause significant damage. These propagating waves, either increasing or decreasing rapidly, are commonly known as a transient hydraulic surge of water hammer that can cause severe damage to liquid product pipelines, vessels, flanges, valving, and associated equipment. 

The Flow Safe SurgeFlow series has been developed exclusively for liquid surge protection. These valves are extremely simple and 100% reliable. The dome cavity volume on top of the main valve piston is filled with nitrogen gas to affect the valve's proper set pressure. Dome gas pressure is set according to the characteristic piston seat-to-seal area ratio for the given valve size. This dome load forces the main valve into a closed position using a soft elastomer seat, providing a 100% tight shut-off. When surge pressure is sensed, the SurgeFlow valve piston opens immediately as the liquid fluid force acting under the piston overcomes the force from the dome gas working on the top. The piston continues to lift in proportion to the pressure surge, slightly compressing the dome gas. The closing cycle responds directly to pressure decay in the piping upstream of the SurgeFlow surge relief valve. 

SurgeFlow series valves are designed for accurate and repeatable performance. They will handle both minimum and maximum surge cases when called upon to relieve. Flow Safe suggests all surge relief valves be located nearest the point where maximum pressure can occur in the main pipeline for optimal safety purposes.

Thermal Flowmeters for Wastewater Applications

Kurz Flowmeter for Wastewater Applications

Wastewater treatment plants ( WWTPs) or publicly owned treatment plants (POTWs) must operate 24/7 to satisfy domestic, industrial, and storm drain sources. Sewage treatment includes eliminating pollutants from wastewater and sewage (human waste, animal waste, soaps, and detergents) to create a safe fluid waste stream that can be reintroduced safely into the ecosystem and a solid waste appropriate for reuse (usually as fertilizer). The primary applications for flow meters in wastewater treatment settings measure blower air to each pool in the aeration basin and measure digester gas flow.

Kurz Flowmeter on Digester
The aeration basin is an array of treatment pools containing aerobic bacteria that break down the pools' sewage. A blower adds the necessary dissolved oxygen (DO) to the aerobic bacteria in the aeration basin. Too little oxygen destroys the bacteria, and too much oxygen is expensive; running the aeration blower accounts for up to 60% of all wastewater power consumed.

Digester sewage is called "sludge." When bacteria is added to the digester, the sludge breaks down and releases gas. This digester gas is collected, compressed, it's excess moisture gets removed, and is then cleaned in a scrubber. The cleaned gas is sent to engines or fuel cells for power generation, boiler water heating (for steam or hot water), and excess gas burns off at the flare. Many extensive sewage treatment facilities use digester biogas to operate the plant, minimizing their grid power consumption.

Developing accurate flow rate data allows wastewater treatment facilities to more precisely manage digester production levels, enabling tighter controls on methane levels and flaring. Kurz Instruments provides a handy overview of where thermal flowmeters are applied and provide optimal performance.

Thermal Flow Meters for Pulp & Paper Applications

Thermal Flow Meters for Pulp & Paper Applications
Trees used in paper-making go through processing in a de-barker and a chipper, where they reduce to approximately one-inch wood chips. The wood chips are pressure cooked in a digester and become pulp, refined, turned into slush, and screened. Screening drains away liquid, and the resulting pulp is then pressed and dried into the paper. Several steps within the pulp and paper-making process create emissions that must be monitored and reported.

Creating paper pulp relies on a careful balance of low-velocity air flows among the various processes. For example, the recovery boiler following the digester modulates to follow the digester load changes. Additionally, a recovery boiler uses the black liquor's chemical reaction to generate heat for the boiler. It has three airflow systems requiring tight control to create stable air flows.

Kurz Instruments provides a good application note explaining the areas where thermal flow meter uses appear in the pulp and paper production process. You can download the application note below.

Ball Valves Used for Black Liquor in Pulping Kraft Process

Black liquor valves

Many toxic, corrosive, and reactive chemicals are used in pulp and paper mills in chemical pulping. This incredibly hostile environment requires well-engineered automatic valve systems and durable valve actuators, spring units, and positioners. 

Suppose you understand how paper is made and what chemicals are usually used in the atmosphere. In that case, you can instantly understand why special consideration is required for valve and actuator selection.

In the early stage of paper production, digesters combine high heat and a heavy alkaline liquid called "white liquor" to convert wood chips into a pulp during separation from wood chips. White liquor (mainly sodium hydroxide and sodium sulfide), process water, heat, and pressure are used to separate wood chips into lignin and cellulose fibers. The white liquor breaks down the lignin (the substance that binds the wood fiber together) in wood chips. The resulting combination of water and spent white liquor produces "black liquor." This liquid pulp residue mixture made up of lignin and hemicellulose, and inorganic compounds such as sodium hydroxide and sodium sulfide is toxic. Another by-product of this process is Hydrogen Sulfide, a toxic, corrosive, and flammable gas. 

Effects on Ball Valves

In piping and ball valves, managing these process chemicals and by-products is difficult. Pipe diameters range from 2"-10", but the most common sizes are 4", 6" and 8." Usually, these processes are ANSI / ASME Class 150 and ANSI / ASME Class 300, the most common end connection being 150 # and 300 #. Process temperatures are usually high, between 250 ° F and 350 ° F. The valve body and end connection materials are generally 316 stainless steel, but you'll also find carbon steel requested. Applications can include manual lever, gear operators, pneumatic actuators, and electrical actuators in valve assemblies.

The most concerning issue is the sticky molasses-like liquor builds upon the ball valve face and contaminates the back seat spaces, inducing strong internal clearance forces, resulting in valve lock-up over long static periods. A superior ball valve seat design from A-T Controls addresses the viscous material problem.  

A-T Controls developed a solution for this extreme pulp and paper service and black liquor service with notable improvements to their FMS series. This valve incorporates a "scraper seat" feature that eliminates the molasses-like residue baked on the ball's face and eliminates valve lock-up. The addition of Aflas ® o-rings seal the seat cavity from media build-up, and a Venturi hole in the ball is also provided.

Typical black liquor ball valve from A-T Controls:

  • Series: A-T Controls FMS
  • Sizes: ½" -8"
  • Rating: ANSI/ASME Class 150/Class 300 with 150# and 300# flanges, API 607.
  • Ball and Seats: Tungsten Carbide coated metal scraper seats (Aflas® o-rings and Venturi Ball for black liquor service.) 

Please consult a Piping Specialties Applications Engineer for material selection for your black liquor application. This information is a guideline, and customers are solely responsible for construction materials, preparation of the valves for service, and lubricants being compatible with their black liquor application.

Radar Level Measurement: Comparison of 24 GHz and 80 GHz

Radar level transmitters are among the most accurate technology choices for process level and storage tank applications for continuous level measurement under demanding conditions.  These transmitters utilize Frequency Modulated Continuous Wave (FMCW) technology that offers superior signal processing capabilities and more reliable measurement than other techniques. The state-of-the-art signal processing capabilities of these transmitters, along with their frequency range, helps to ensure optimum application coverage.

24 GHz radar transmitters cover a broad range of applications, including liquids & solids. 

80 GHz radar transmitters are especially beneficial for level measurements in narrow tanks with internal obstructions due to their small beam angle.

This video, courtesy of AMETEK Drexelbrook, demonstrates many of the other differences between 24 GHz and 80 GHz models of radar level transmitters.
