Brooks Instrument GP200 Pressure-based Mass Flow Controllers (MFC): Theory of Operation


Brooks Instrument presents the theory of operation behind their pressure-based mass flow controller (P-MFC) from their GP200 series in this video. This P-MFC has a unique design approach for enhanced process performance without the limitations of today's traditional P-MFCs. A traditional P-MFC system includes:
  • An upstream pressure transducer.
  • An upstream control valve.
  • Two individual pressure transducers.
  • Laminar flow element.
The use of an upstream valve has many disadvantages. This design requires high pressure making it sub-optimal for critical low-pressure gases and low full-scale flow rate. It also means matching the two individual pressure transducers perfectly. 

Brooks Instrument designed a patented integrated differential pressure transducer, GP200 P-MFC, to address the disadvantages. The GP200 has one actual differential transducer instead of two, eliminating the need to match the two individual pressure transducers, significantly reducing measurement uncertainty, and improving accuracy, particularly for critical low vapor pressure process gases. Its downstream valve architecture will operate at much lower inlet pressures and across a broader range of pressures. The downstream valve also minimizes the bleed-down effect and ensures that the device is insensitive to dynamic outlet conditions.

The GP200 Series P-MFC features a patented architecture that overcomes the limitations of conventional P-MFCs to provide the most precise process gas delivery even when delivering low vapor pressure process gases. It includes several unique design aspects, including an integrated differential pressure sensor coupled with a downstream valve architecture enabling the most precise process gas delivery over the industry's broadest range of operating conditions.

Since GP200 Series supports a broad range of process conditions, it can be used as a drop-in replacement and upgrade for many traditional P-MFCs and thermal MFCs. It reduces the complexity and cost of ownership of the gas delivery system because it eliminates the need for components such as pressure regulators and transducers.

GP200 FEATURES

  • True differential pressure measurement
  • Lower inlet pressure operation
  • Downstream valve architecture
  • Matched transient response
  • Zero Leak-by Control Valve
  • MultiFlo™ technology offers unparalleled flexibility—one device can be programmed for thousands of different gas and flow range configurations without removing the MFC from the gas line or compromising accuracy
  • Local display indicates flow, temperature, pressure and network address
  • DeviceNet™, EtherCAT®, RS-485 L-Protocol and analog interfaces

GP200 BENEFITS

  • By removing the requirement to match and compensate two separate pressure transducers, the GP200 differential pressure technology reduces measurement uncertainty for enhanced accuracy, repeatability and drift performance.
  • Safer fab operation at lower inlet pressures is now achievable with a P-MFC due to the GP200 differential pressure sensor that is specifically optimized for low differential pressure measurement.
  • The downstream valve architecture ensures accuracy is independent of downstream pressure, enabling flow delivery into pressures as high as 1200 Torr. The fast closing valve addresses non-productive recipe wait times, or "tail effects," seen in upstream MFC valve designs that require additional time to bleed down their internal volume of gas.
  • Ultra-fast, highly repeatable ascending and descending flow stabilization time enables tighter process control in advanced high cycle Deposition and Etch processes.
  • 100X improvement in valve shut-down
  • With MultiFlo™, MFC full scale flow range can be re-scaled down typically by a factor of 3:1 with no impact on accuracy, turndown or leak by specifications, for optimum process and inventory flexibility 
  • Convenient user display and independent diagnostic/service port aids device installation, monitoring and troubleshooting

Schubert & Salzer Sliding Gate Control Valves from Miller Energy


The sliding gate control valve from Schubert & Salzer has an innovative design that allows it to handle complicated applications requiring precise control under challenging circumstances. The sliding gate valve's actuation power is roughly 10% that of a globe valve of the same nominal size and differential pressure, even if both designs have almost the same flow rate.

The valve handles steam, liquids, and gases. Sliding gate valves outperform traditional control valves and use smaller actuators because they require reduced actuating force. They provide lower weight and reduced installation dimensions due to the space-saving wafer design, especially in nominal sizes mid-large. 

Due to the unique design, harmful cavitation zones occur 1 - 2 meters beyond the valve in the case of a sliding gate valve, placing the destructive cavitation bubbles downstream, in the pipeline's center, causing no damage.

Vaisala K Patents Refractometers - Refractive Index Measurement


Vaisala K-PATENTS Process Refractometers provide in-line solids and density measurement  for liquids for process control and industrial automation. 

Vaisala K-PATENTS Process Refractometers are commonly used to determine the liquid concentration or density. This measurement has been an essential element in the processing industries for over a century in all sectors, including refining, paper production, pharmaceuticals, food and beverage, and chemical manufacturing. , 

The measurement principle is critical angle measurement. The refractometer has three main components: a light source, a prism, and an image detector.  

The light source sends light rays to the prism and process interface at different angles. Rays with a steep angle are partly reflected in the image detector and partially refracted to the process. The angle from which the total reflection starts is called the critical angle. A CCD camera detects a bright field and a dark field corresponding to partly reflected light and totally reflected light. The borderline position between the bright and the dark area correlates with the critical angle which is a function of the refractive index and therefore correlates with the concentration of the solution.

Calibration of a 4-20 mA Transmitter in a Hazardous Area Using a Portable Calibrator

This video demonstrates how to calibrate a 4-20 mA transmitter in a hazardous environment using a portable calibrator, in this case, the WIKA CPH7000 Ex.

Before you do calibrations in a hazardous (Ex) space, you must be aware of several things. There are many levels of dangerous areas, as well as various levels of calibrating equipment to choose. A hazardous location includes or may contain combustible substances (whether indoors or outdoors). It could be a liquid, gas, vapor, or dust that is combustible. Depending on the hazardous area classification, a flammable substance may be present all of the time, a particular percentage of the time, or just in specific instances, such as during shutdowns or accidents. 

In the best of circumstances, calibration can be a challenging task. Doing so in an area with a risk of explosion raises the complexity level to a new level, requiring the technician to have the necessary training and equipment. The WIKA CPH7000 Ex process calibrator is a precise, easy-to-use portable instrumentation calibrator that tests process transmitters in hazardous areas.

Pulse Burst Radar Level Transmitters

Pulse Burst Radar Level Transmitters

Pulse Burst Radar sends short bursts of energy to the surface of a liquid. The time it takes for a signal to be reflected off the liquid surface is measured by ultra-high-speed timing circuitry. 

Filtering out false reflections and other background noises is accomplished through sophisticated signal processing. The precise level is then calculated by taking tank height and additional configuration information into account. Because the circuitry is highly energy-efficient, no duty cycling is required, as with other radar devices. This enables the device to track rapid level changes of up to 4.5 m/minute (180"/min). 

Magnetrol uses Pulse Burst Radar for Radar level measurement rather than frequency modulated continuous wave (FMCW), which is today's more common operational technology. Pulse Burst Radar operates in the time domain and does not necessitate the complex and costly processing required for FMCW. 

Pulse Burst Radar is more efficient at sorting through extraneous echoes and selecting the one reflected by the actual level because echoes are discrete and separated in time. Pulse Burst Radar also has excellent averaging characteristics, vital in applications where the return signal is affected by the factors described in "Don't Forget the 3 D's of Radar" below. 

Unlike actual pulse devices, which send a single sharp (fast rise-time) waveform of wide-band energy, Pulse Burst Radar sends out short bursts of 6 GHz or 26 GHz energy and measures the transit time of the signal reflected from the liquid surface. The following equation is used to calculate distance:

Distance = C x Transit Time/2, (where C = Speed of Light)

The level value is then calculated by taking tank height and other configuration information into account. The sensor reference point – the bottom of an NPT thread, top of a BSP thread, or face of a flange – is the exact reference point for distance and level calculations. 

Remember the 3 D's of Radar 

Three fundamental conditions influence radar applications: 

  • The process medium's dielectric; 
  • The application's distance, or measuring range; and 
  • A wide range of disturbances can weaken or distort the radar signal. 

Low dielectric media can weaken radar's return signal, reducing the effective measurement range of a device. Pulse Burst Radar provides accurate measurements even in low dielectrics. However, when the dielectric is extremely low, as with liquid gas, fuels, and solvents, or when boiling and/or flashing can occur, Guided Wave Radar (GWR) may be the better choice in radar technology. 

The distance, or measurement range, of Pulse Burst Radar, is determined by the antenna used, the dielectric constant of the medium, and the presence of signal interference. Turbulence, foam, false targets (interior tank obstructions causing false echoes), multiple reflections (reflections off the tank roof), and a frequent level change rate can all weaken, scatter, or multiply radar signals. Excessively high or extremely low liquid levels can also be problematic. 

The Processing of Signals 

Because radar exhibits interference effects similar to those seen in light, the signal processing function is critical. The quality of a device's signal processing is what distinguishes today's cutting-edge radar transmitters from the rest. 

Pulse Burst Radar extracts accurate levels from false targets and background noise through its sophisticated signal processing capabilities. Because pulse burst radar circuitry is highly energy-efficient, no duty cycling is required to achieve effective measurement. As a result, Pulse Burst Radar can track high rates of change that would be impossible to track with other loop-powered radar transmitters. Although Pulse Burst Radar has a robust false target recognition and rejection routine, proper installation significantly minimizes false target reflections. 

Antennas 

The radar signal is transmitted and received by the antenna on the transmitter. Each antenna's maximum measuring range is primarily determined by dielectric constants and the degree of turbulence. Horn antennas can measure dielectric media as low as 1.4, whereas rod antennas have a minimum dielectric of 1.7. 

Benefits 

Pulse Burst Radar measures a wide range of media accurately and reliably in a wide range of process conditions, from calm product surfaces and water-based media to turbulent surfaces and aggressive hydrocarbon media. As a non-contact device, Pulse Burst Radar is immune to the complications that can occur when a probe comes into contact with the process media, such as coating from high viscosity media or corrosive attack from aggressive chemicals. Given the cost of extended probe lengths, the greater the measuring range, the more radar proves to be the cost-effective solution. Temperatures, pressures, the presence of vapors, and air movement within a vessel's free space have little effect on the radar. Specific gravity, conductivity, and dielectric constant changes do not affect measurement accuracy. The lack of moving parts in a 100% electronic instrument translates into low maintenance costs, and, as a two-wire, loop-powered device, power requirements and installation are greatly simplified.

Magnetic Level Indicators and Controls for Industrial Process Applications

Magnetic Level Indicators and Controls

Fluid process control operations frequently involve the storage of liquids in a vessel or tank. The continuous and accurate indication of the liquid level within the tank is an important data point for process control decision making and safety. Several tank level measurement methods and instrument types are available, each with its own set of characteristics that may be advantageous for a specific installation. 

A tank liquid level indicator's selection criteria often include: 

  • Does the process require direct or indirect measurement of level?
  • What level measurement accuracy and reliability is needed?
  • What is the tank shape, regular or irregular?
  • Are there concerns with media compatibility with measurement device materials of construction?
  • How often will maintenance or calibration be needed?
  • Is the instrument capable of operating at the process temperature and pressure for the application?
  • Does the application require local display and visibility or remote?
  • Are control signals from the level indication required? What type and transmission protocol?
  • What kind of redundancy and safety devices, such as additional switches, are needed?

Magnetically coupled liquid level indicators, or MLIs, are widely used in the process industry. They are accurate, consistent, and reliably indicate liquid level. These units are completely sealed and do not require any maintenance. MLIs also eliminate the vapor or liquid emission issues that plague sight and gauge glasses. 

Most Compelling Reasons for Using MLI's:

  • Level measurement is continuous. 
  • Operable without the use of electricity. 
  • Regardless of tank shape or profile, they provide a direct visual tank fluid level indication. 
  • They are available in wide operating temperature and pressure ranges. 
  • MLI construction is resistant to breakage.
  • A variety of materials are available to accommodate corrosive media. 
  • Externally mounted measuring indicators, switches, and transmitters do not come into contact with the process media. 
  • MLI's provide a continual operation that requires little maintenance. 
  • The level indication is viewable from a greater distance than glass sight gauges. 
  • With a single instrument, it is possible to measure large fluid level ranges.

Magnetic level indicators have a strong presence in tank liquid level measurement and should be considered a candidate for meeting those application requirements. There are numerous options for customizing the level indicator for each application.  Work with your local Sales Engineer,  a specialist in level measurement, about your application challenges and positive outcomes.

Choosing the Right Industrial Level Technology In Foaming Situations

In the chemical, manufacturing, food and beverage, life sciences, and other process industries, foam is sometimes a problem in liquid tanks. There is no "one-size-fits-all" level measurement option for foam because of its fluid nature. Understanding the properties of the foam and the type of measurement required is critical. Foam can form in a tank for various causes, including injecting air or gas into the liquid or agitator/mixing blade activity. Understanding the nature of the foam and the process is essential to minimize potentially costly errors when choosing a level measurement technique, regardless of the source.

Selecting Variable Area Flow Meters for Process Flow Measurement

Variable Area Flow Meters

Many industrial processes involve the movement of fluid product components, either liquid or gaseous, through pipes. Because processing is about control, an input to the facility's management, measurement, or data logging centers will answer the query, "How much is going through that pipe?" 

In the industrial process measurement and control industry, there are several ways for quantifying flow, each with unique characteristics that may be useful under certain operating situations. All flow measuring methods are indirect because the actual measurement is of a character influenced predictably by a change in the media flow. Flow measurement is a critical component that, when paired with other fluid properties, is used to calculate the total mass of a fluid passing through the measurement site. 

The variable area meter, commonly known as a rotameter and VA meter, is a tried and true flow measuring device that operates by creating an equilibrium between an upward force created by fluid motion and a downward force, gravity. A tapering glass or metal tube encases a specifically shaped float, also known as a shaped weight, in the device. VA meters must be positioned vertically, with the media flowing upward from the bottom, so that the gravity force required for functioning is correctly aligned with the flow direction. As fluid flows upward via the precisely tapered tube, drag is created on the float enclosed within the tube, pulling it upward. As the float rises, the open space between the float and the tube wall expands, causing the fluid velocity and drag force to decrease. The flow velocity within the tube will cause the weight to climb for any given flow volume until the drag force generated by the flow reaches equilibrium with the countervailing power of gravity on the float. The tube and float are well designed, allowing for an immediate indication of flow volume.

Variable area flowmeters have the following operating characteristics: 

  • There is no need for external power or fuel for functioning. 
  • Vertical installation is required, with flow arriving at the bottom. 
  • Meters are calibrated to a given chemical and temperature. 
  • The operation is stable and has a modest pressure drop. 
  • For operation, constant gravity is required. 
  • Flow rate can be read locally using a meter or a scale inscribed on the tube. 
  • The visibility of the float through the medium is required for unit flow readings using glass tubes. 
  • For industrial flow metering equipment, accuracy is relatively low. 
  • Inexpensive upkeep, simple construction, and low comparative cost.

Brooks Instrument, a world-renowned maker of flow, pressure, and level measurement equipment, created a brief paper highlighting the parameters to consider when specifying a VA meter and how each aspect influences the unit's performance. The description is realistic and straightforward to grasp. It is suggested reading for all process stakeholders who want to improve their flow measuring skills.

Process Refractometers for Water Treatment Chemical Concentration Monitoring

Process Refractometers for Water Treatment


INTRODUCTION


Pure water treatment removes undesirable chemicals, biological contaminants, suspended solids, and gases from raw water. Water purification aims to produce water for a specific purpose, such as human consumption and medical or industrial use.


Polyaluminium coagulants are increasing use in potable water treatment plants, particularly for soft, colored surface waters. Polyaluminium chloride (PACl) is gradually replacing Alum (aluminum sulfate), a commonly used coagulant in water treatment plants. Alum coagulates at a limited pH range (between 5.5 and 6.5) and often requires alkali to the raw water to achieve the optimum coagulation pH. Furthermore, the alum floc produced is particularly fragile, which is vital if a coagulant is required to maximize color removal in a microfiltration-based water treatment process.


K-Patents Teflon Body Refractometer PR-23-M from Miller Energy, Inc.


APPLICATION


Water treatment by chemical precipitation is a complex process. It starts with adding flocculants, specifically, Polyaluminium Chloride (PACl) and Sodium Hydroxide (NaOH). PACl is a synthetic polymer dissolved in water. It precipitates in big volumetric flocs, which absorb suspended pollutants in the raw water. The turbidity of the raw water defines Polyaluminium Chloride quantity. PACl concentration must be higher than 10 % To keep the flocculation process smooth. Polyaluminium Chloride is stable in the storage tank; however, it tends to crystallize after some time. Vaisala K-PATENTS® refractometer monitors the concentration of PACl to inform about the need for tank or pipe cleaning, thus preventing blockage caused by the PACl crystals.


NaOH regulates pH level, increases alkalinity, and neutralizes acids in the water. In alkaline water, the coagulation and flocculation processes work more effectively. Moreover, sufficient alkalinity prevents dissolving the lead from pipes and pipe fittings and reduces the corrosive effect of the water to iron pipes.


Further, particles suspended in water start to precipitate and agglomerate to form larger particles, known as flocs. The flocs are then settled at the bottom, forming sludge, and then removed from the process. After separating most of the floc, the remaining suspended particles and unsettled floc get filtered to remove water.


In the filtration phase, the water goes through the layers of anthracite, sand, and gravel. As a result, organic compounds contributing to taste and odor get removed. Other remaining particles get trapped by adhering to the sand and gravel particles.


After harmful micro-organisms get removed through filtering, it is necessary to add disinfecting chemicals to the water to inactivate any remaining pathogens and potentially harmful micro-organisms. One of the disinfecting chemicals used is Sodium Hypochlorite (NaOCl). When dissolved in water, this chemical releases chlorine, which is an efficient and safe disinfectant if added in a sufficient amount. Apart from sodium hypochlorite, liquid chlorine and chlorine dioxide are also choices as disinfectants.


Fluoride may also be added to the water to reduce tooth decay and prevent chronic diseases. However, fluoride in the water must not exceed recommended levels. Excessive levels of fluoride can be toxic or cause undesirable cosmetic effects such as staining of teeth.


Sodium Hypochlorite is unstable and quickly decomposes. The stability of NaOCl solution is dependent on the following factors:


  • Hypochlorite concentration
  • The temperature of the solution
  • PH value of the solution
  • The concentration of the impurities during catalyzing decomposition
  • Exposure to light


With the process refractometer, it is possible to monitor NaOCl concentration and control the disinfection conditions.


The water purification disinfection stage happens in the disinfectant basin. Then, corrosion control assures the high quality of the purified water. Finally, the pure water gets stored for further consumption.


INSTRUMENTATION AND INSTALLATION


Vaisala K-PATENTS® Teflon Body Refractometer PR-23-M provides in-line measurements of Polyaluminium Chloride and Sodium Hydroxide at the initial stage of purification, ensuring the efficient flocculation of undesired particles. In addition, through the measurement of Sodium Hypochlorite and Fluoride at the water disinfection stage, high-quality purified water at the outlet is assured.


Refractometer installations happen in three different points in a by-pass loop between each chemical tank pump outlet and the treatment point. The refractometer allows monitoring the chemicals concentration at the exit from the storage tank to the pipe treatment point.


Typical measurement ranges are:

  • PACl is ca. 10-11 %
  • NaOH is ca. 40-45 %
  • NaOCl is ca. 8-12 %

How Proper Level Instrumentation Can Alleviate Foam Headaches

Proper Level Instrumentation for Foam

Foam is at times present in liquid tanks used in the chemical, manufacturing, food and beverage, life sciences, and other process industries. Because of foam's fluid nature, there is no such thing as a "one-size-fits-all" level measurement solution. It's essential to understand the foam's characteristics and understand what form of measurement is needed. The foam may develop in a tank for several reasons, such as introducing air or gas into the liquid or the activity of agitators/mixing blades. Regardless of the source, caution is required when selecting a level measurement technology to avoid potentially costly errors. 

Magnetrol, a world-leading manufacturer of level instrumentation, authored a white paper that aims to go through the challenges that foam presents and overcome them by recommending proper instrumentation.
