Chlorine Gas Flow Meter in Chlorinator System

FCI Model ST100L

Chlorinators are a frequently used system for water disinfection in municipal and industrial water treatment processes.

Problem

The chlorinator system’s flow measurement system was drifting which resulted in poor control over the amount of chlorine being used. The system was initially supplied with simple, site-gauge rotameters and later, for automation and control, differential pressure (dP)-type orifice plate flow meters were added. The dP meters were continuously drifting out of calibration and could not be relied upon to accurately signal the chlorine dispensing control system.




Flow Conditions

  • Pipe diameter: 1 ʺ [DN25]
  • Flow rate: 150 lb/day to 2,000 lb/day [68 kg/day to 907 kg/day] Temperature: 60 °F to 100 °F [16 °C to 38 °C]
  • Pressure: 0 psig to 10 psig [ 0 bar(g) to 0.7 bar(g)]
  • Media composition: Chlorine gas
  • Straight run: Limited, inadequate
  • Flow range encompasses transitional region

Solution

FCI Model ST100L constant power technology thermal flow meter was installed in the chlorine gas inlet line to the chlorinator panel. The flow body included built-in Vortab ® flow conditioner to overcome both lack of straight-run and transitional flow region to provide repeatable flow profile and accurate measurement. The ST100L sensor element and flow body, including Vortab flow conditioner, are fabricated of Hastelloy C-276 for protection and long service life in highly corrosive chlorine. Because chlorine gas is a safety issue for calibration labs and air equivalency calibrations for chlorine are inadequate, FCI provided on-site start-up assistance which included calibration adjustments based on the site’s rotameter measurements.

Energy Metering Through Flow Measurement in District Energy Systems

Energy Metering in District Energy

Modern power plants operate according to the environmentally friendly principle of combined heat and power (CHP), where electricity and heat are generated in a single process. Combined heat and power utilizes wasted heat from electric generation to increase the efficiency of power plants. In many cities the heat is transported in the form of hot water via pipelines to the respective districts. Implementation of CHP is often driven by reliability requirements for critical facilities such as hospitals, data centers, or research labs. Flow and thermal energy metering at these pipelines is crucial for fulfilling their safety functions in case of necessary line shut downs, as well as for network balancing and pump regulation.

Energy Metering in District EnergyWhether you are running an entire facility, optimizing a central power plant or developing a plant for the next expansion of your campus, precise measurement of existing utilities is essential in making the choices necessary to operate your present scheme or designing for future needs. Accurate flow measurement starts with the selection of the correct technology for the implementation, the correct installation of the meter and controllers, with the return of the data to the building automation system (BAS) and energy management software (EMS).

Goals for an Efficient Energy Metering Scheme
  • Reduce energy costs
  • Measure energy use
  • Improve reliability of system
  • Improve space conditions
KEP Flow Computer
KEP Flow Computer
The flowmeter and flow computer are ideal for metering energy consumption in heated / chilled water and steam applications, and are often teamed together to provide an accurate system that provides mass flow information, corrects volume flow, and computes heat flow. This data is then provided to the BAS/EMS for further analysis.

A flow computer is a special purpose device which computes a corrected flow based on information derived from raw input signals and stored sensor and fluid properties information.

A number of flow metering devices are available, each having strengths and weaknesses in connection with specific applications. The types include:
Many of these flow sensors require linearization from the flow computer to improve accuracy. The flow computer is also used for data logging, communication, remote metering, alarming and control functions.

New standards require that measurement devices be installed to monitor the electrical energy use for total energy used for heating, ventilating, and air-conditioning (HVAC) systems. Working with experts who fully understand the accuracy, reliability, and affordability of the flow metering equipment is critical to a successful implementation.

US Power Grids, Oil and Gas Industries, and Risk of Hacking

A report released in June, from the security firm Dragos, describes a worrisome development by a hacker group named, “Xenotime” and at least two dangerous oil and gas intrusions and ongoing reconnaissance on United States power grids.

Multiple ICS (Industrial Control Sectors) sectors now face the XENOTIME threat; this means individual verticals – such as oil and gas, manufacturing, or electric – cannot ignore threats to other ICS entities because they are not specifically targeted.


The Dragos researchers have termed this threat proliferation as the world’s most dangerous cyberthreat since an event in 2017 where Xenotime had caused a serious operational outage at a crucial site in the Middle East. 

The fact that concerns cybersecurity experts the most is that this hacking attack was a malware that chose to target the facility safety processes (SIS – safety instrumentation system).

For example, when temperatures in a reactor increase to an unsafe level, an SIS will automatically start a cooling process or immediately close a valve to prevent a safety accident. The SIS safety stems are both hardware and software that combine to protect facilities from life threatening accidents.

At this point, no one is sure who is behind Xenotime. Russia has been connected to one of the critical infrastructure attacks in the Ukraine.  That attack was viewed to be the first hacker related power grid outage.

This is a “Cause for Concern” post that was published by Dragos on June 14, 2019

“While none of the electric utility targeting events has resulted in a known, successful intrusion into victim organizations to date, the persistent attempts, and expansion in scope is cause for definite concern. XENOTIME has successfully compromised several oil and gas environments which demonstrates its ability to do so in other verticals. Specifically, XENOTIME remains one of only four threats (along with ELECTRUM, Sandworm, and the entities responsible for Stuxnet) to execute a deliberate disruptive or destructive attack.

XENOTIME is the only known entity to specifically target safety instrumented systems (SIS) for disruptive or destructive purposes. Electric utility environments are significantly different from oil and gas operations in several aspects, but electric operations still have safety and protection equipment that could be targeted with similar tradecraft. XENOTIME expressing consistent, direct interest in electric utility operations is a cause for deep concern given this adversary’s willingness to compromise process safety – and thus integrity – to fulfill its mission.

XENOTIME’s expansion to another industry vertical is emblematic of an increasingly hostile industrial threat landscape. Most observed XENOTIME activity focuses on initial information gathering and access operations necessary for follow-on ICS intrusion operations. As seen in long-running state-sponsored intrusions into US, UK, and other electric infrastructure, entities are increasingly interested in the fundamentals of ICS operations and displaying all the hallmarks associated with information and access acquisition necessary to conduct future attacks. While Dragos sees no evidence at this time indicating that XENOTIME (or any other activity group, such as ELECTRUM or ALLANITE) is capable of executing a prolonged disruptive or destructive event on electric utility operations, observed activity strongly signals adversary interest in meeting the prerequisites for doing so.”

Variable Area Flow Meters

Variable area flow meters

Variable area flow meters, also referred to as Rotameters, 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.

Variable Area Flow Meters: An Overview 

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

Important elements of a 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 Variable Area Flow Meters 

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

Glass Tube Variable Area Flow Meter

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 variable area flow meter
Metal Tube
Rotameter
(Brooks)

Metal Tube Variable Area Flow Meter

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 or gas metering
  • Liquid, gas, or oil flow measurement
  • Chemical injection
  • Rotating equipment flow measurement
  • High-pressure flow meters for offshore oil platforms

Electromagnetic Flowmeters and Dual Frequency Excitation

Magnetic flowmeter
(Yokogawa)
The electromagnetic flowmeter, commonly known as the "magmeter", gets its name from the magnetic field generated within the float tube that produces a signal proportional to flow. This principle employs Faraday's Law of Electromagnetic Induction. Magnetic flowmeters are built so the direction of the magnetic field is perpendicular to the flow and the line between the electrodes is also perpendicular to the flow. As a conductive liquid flows through the flowtube, an electro-motive force is generated. The electrodes detect the electro-motive force. The electro-motive force is proportional to the flow velocity, flux density, and the meter inner diameter. The flux density of the magnetic field and the meters inner diameter are constant values, therefore the magnetic flow meter can calculate the flow velocity and volumetric flow from the electro-motive force.

The basic components of the magnetic flow meter body are:
  • A lined flowtube (typically Teflon)
  • Excitation coils
  • Two electrodes mounted opposite of each other within the flowtube.
Current is applied to the coils in the magmeter to generate a magnetic field within the flow tube. As a conductive fluid flows through the meter, an electro-motiveforce is generated. This force is detected by the electrodes and the resulting value is converted to flowrate.

When magnetic flow meters were originally designed over 50 years ago, they utilized AC type excitation. AC powered magnetic flow meters use line frequency to generate the magnetic field. The frequency of AC excitation is typically 50 to 60 Hertz. This type of excitation has a very fast response time, making it suitable for slurry applications. The weakness of AC type excitation is that it has an unstable zero, and the accuracy is a percent of span, as opposed to a more accurate percent of reading. Because this type of excitation uses line frequency, the power consumption is also very high, making this an expensive meter to operate.

AC and DC excitation
Dual AC and DC excitation
In an effort to improve accuracy and reduce energy cost, pulsed DC type excitation was introduced several years later. The average excitation frequency is between three to eight Hertz, but can go as high as thirty Hertz. The major benefits of pulsed DC excitation over AC excitation is the improved accuracy and zero stability. The accuracy of a DC type meter is a percent of reading. This gives you a more accurate measurement throughout the entire measuring range. Unfortunately, because of the low frequency, the response time is very slow, making it a poor choice for noisy applications.

To overcome the disadvantages of the standard AC and DC excitation methods, and keep the advantage of a high signal-to-noise ratio, Yokogawa's patented dual frequency excitation is the ideal combination. Dual frequency excitation combines the positive benefits of both AC and DC excitation, using both a high 75 Hertz frequency, and a low frequency excitation of approximately six Hertz to drive the coils. Dual frequency excitation is an innovative method that superimposes high frequencies on low frequencies, and utilizes the advantages of each, while eliminating the previously discussed disadvantages. The combination of these methods results in the flow noise immunity and fast response of the high frequency excitation method, and the high zero stability of the low frequency excitation method simultaneously.

Steam Use Measurement Presents Unique Challenges for Colleges and Universities

Steam poses a unique challenge for colleges and universities.

Many schools want to accurately track, and then internally bill, for steam usage in each of their buildings as part of a wider effort to improve resource management. However, traditional steam metering technologies tend to be a less than optimal choice.

Most times, it’s necessary to place campus steam meters in the basements of buildings where there isn’t a lot of room for piping. That causes issues because flow meters typically require significant runs of straight pipe upstream and downstream of the meter to work correctly.

School administrators also encounter issues by trying to measure steam usage during the low-demand summer months. Common vortex meters, which contain a shedder bar mounted across the diameter of a pipe to measure flow, work well at higher flows. When it comes to low flows, however, they can stop working completely (i.e., low flow cutoff problems). Differential pressure (DP) flow meters coupled with the proper electronics, by comparison, can push the low flow cutoff value downward. However, most DP meters can’t get around the straight-run requirements.
ExactSteam™ V-Cone® Flowmeter
The ExactSteam™ Solution

McCrometer’s ExactSteam solution is designed to overcome those hurdles.

The ExactSteam V-Cone Flowmeter works well with short straight-pipe runs, so it addresses the lack of space issues faced by colleges and universities. It also measures steam across the entire range, performing better at lower flows.

The High Cost Of Low Flow Cutoff

Steam system operators can pay a steep price for generating product that passes through a meter but fails to get measured. Also known as low flow cutoff, those losses are a function of the turndown ratio of flow meters. The ratio — defined as the maximum measurement capability of a device compared to its minimum — dictates how wide a flow spectrum can be measured. On campuses, this creates a major issue because demand for steam in the colder weather can be extremely high compared to off-peak times.

McCrometer’s ExactSteam
ExactSteam™ V-Cone® Flowmeter
ExactSteam is a DP-style flow meter that can be adjusted for colleges during winter months. It contains McCrometer’s established V-cone flow meter combined with a newer electronics package to aid in the downward adjustment of the turndown ratio. A growing number of college campuses, especially larger schools, are seeing the benefits of ExactSteam and adopting the technology.

Some examples include:

Case Study #1 - An East Coast University Steam Operation

This school designed its system to measure from 84,000 lbs/hr to 8,400 lbs/hr, which accounted for a 10:1 turndown ratio and velocities of 420’/second to 42’/second. After the meter was installed, system operators determined their actual flow range was 20,000 lbs/hr to 1,000 lbs/hr (a 20:1 turndown ratio) and velocities were 100’/second to 5’/second.

Because flow rates were overstated, the university dropped below the low flow cutoff and wasn’t measuring at all during the off-season.

The solution: Purchase another meter with a larger cone that would produce more differential pressure at the correct flows. The school has since installed an ExactSteam V-Cone Flowmeter.

Case Study #2 – A University Hospital Using Both Condensate And Steam Meters

During the winter, the steam meters were always measuring more steam than the condensate meters.  The difference was justified because the condensate meters were not capturing steam usage of the autoclaves.  However, during the summer, the condensate meters were measuring more than the steam meters, which was impossible.

The steam meter was designed for flows from 14,000 lbs/hr to 1,400 lbs/hr.  During the summer months the hospital flows frequently dropped below 1,400 lbs/hr, which was below the low flow cutoff.  It was also determined that their highest flow during the summer was 5,000 lbs/hr.  The hospital needed more turndown and a lower flow range.

The solution: The ExactSteam V-Cone Flowmeter was installed.  It was designed for flows from 6,000 lbs/hr to 300 lbs/hr and was able to fit in the basement between two elbows.

Well Positioned For Campus Use

Key aspects of McCrometer’s ExactSteam solution include: a complete flow meter for steam metering, factory-configured for energy metering or mass flow; the ability to measure saturated (dry), superheated, and unsaturated (wet) steam; the V-Cone acts as its own flow conditioner by disrupting all centralized flow disturbances; signal stability allows it to measure a wider range of flow than other meters, minimizing pressure loss; and minimum installation requirements, so retrofitting and new installations are easier.

Because of the inherent conflicts, traditional steam metering technologies are not a good fit for many colleges and universities. However, there are solutions available to campus steam system operators to capture readings from most — if not all — of their steam production, even in less than ideal conditions.

New Adaptive Sensing Technology for Thermal Mass Flow Meters

With the launch of its state-of- the-art ST80 Series thermal mass flow meter featuring breakthrough Adaptive Sensor Technology™ (AST™), the process industry’s air/gas flow measurement bar has been reset higher again for rangeability, accuracy, extended service life, reliability and application-matched solutions by Fluid Components International (FCI).

FCl’s innovative (AST™) thermal mass flow technology for the ST80 flow meters features an innovative hybrid sensor drive. This patent-pending measuring technique combines, for the first time, both of the industry’s highly proven constant power (CP) and constant temperature (CT) thermal dispersion sensing technologies in the same instrument. Complementing this new measurement drive technique are a choice of four different flow sensor element designs to further ensure best installed performance, including FCI’s new wet gas solution.

When operating in AST mode, the new ST80 flow meters measure in CT during start-up and through the lower flow ranges, and will then seamlessly shift into CP mode at mid-range and higher flow rates. The result is a best of both technologies performance level where the advanced ST80 meters deliver extremely fast response with extended measuring ranges, at low power consumption to maximize sensor reliability and reduce instrument energy expenses.

Heavy Duty Portable Ultrasonic Water Flow Meter for Long-Term Field Measurement Situations

FLUXUS F401

FLEXIM, the leader in clamp-on ultrasonic flow measurement, has a new portable flow meter designed for long-term field measurement situations.

Depending on programming, the FLUXUS F401 can operate autonomously for long periods, up to several months. This makes it perfect for leak detection investigations and hydraulic studies - anywhere regular, long-term measurements are needed.

FLUXUS F401Built with the water and wastewater industries in mind, the clamp-on ultrasonic flow meter system has is installed without process interruption and installation only takes a few minutes. From then on, the FLUXUS F401 delivers highly accurate and highly repeatable measurements that are not affected by drift. Its low flow capability (down to 0.01 m/s) makes the FLUXUS F401 perfectly suited for monitoring drinking water networks, where low flow velocities are common. The combination of strong signal output and internal noise suppression technology allows the FLUXUS F401 to be used confidently on very large pipes and challenging materials such as rusty steel, badly manufactured GRP, or even armored concrete pipes. These situations are not a metering challenge to the FLUXUS F401.

The product is designed from the ground up for regular heavy duty use in very rough conditions. All parts of the FLUXUS F401 are built to last. Metal sheathing of  protects the the transducer cable ends from tight bending as well as cuts, and ensures tangle-free operation. A six meter cable length of the IP68 transducer accommodates installation of the transducers in deep manholes, with the transmitter being safely located in the upper part of the manhole. The transmitter itself is housed in a robust case with IP67 protection.

Industrial Automation and the Implementation of Wireless Technology

The use of wireless technology in industrial automation systems offers a number of potential benefits, from the obvious cost reduction brought about by the elimination of wiring to the availability of better plant information, improved productivity and better asset management.

However, its practical implementation faces a number of challenges: not least the present lack of a universally agreed standard. This article looks at some of these challenges and presents the approach being taken by Yokogawa.

Understanding the Operation of Thermal Mass Flow Controllers


In this video, Brooks Instrument presents the operation of thermal mass flow controllers.

Mass Flow Controllers are also referred to as MFCs. The basic construction of mass flow controllers consists of four main components. A body, a thermal sensor, a printed circuit board and a magnetic control valve. As gas enters the flow body, a laminar flow element or restrictor diverts precise portion of the gas to pass through the thermal sensor. The thermal sensor is the heart of the mass flow controller, and consists of a bypass tube fitted with a heater element and two temperature sensors. As gas enters the sensor bypass tube, the upstream and downstream temperature sensors measure the temperature differential between gas entering the bypass tube and exiting the bypass tube. 

When choosing an MFC supplier, consider whether the manufacturer provides a zero stability specifications, also known a sensor stability. This indicates the devices ability to maintain accuracy over time. Good sensor stability ensures the MFC delivers highly accurate and consistent results with less frequent recalibration or replacements needed. A stable, accurate sensor guarantees stable, accurate process control. As the thermal sensor measures the change in flow temperature,  it sends a signal to the circuit board, which interprets the data into flow output and compares it to the set point received from the user set point signal. If the set point, or required value, is higher than the measured value or flow output, the controller will open the control valve, letting more flow through. If the set point is lower than the flow output, the control valve will close, decreasing flow. This happens when a coil inside the magnetic control valve sends an electrical current around a valve stem, which moves the valve plunger by thousands of an inch. The circuit board is the brain of the device, so pay close attention to the electronics and firmware architecture when evaluating an MFC. The device should have the ability to support advanced alarms and diagnostics to monitor and correct issues before the overall process is negatively affected. Check to see what built in alarms and diagnostics are available. 

Brooks Instrument devices support not only flow output, but additional alerts like flow totalization, valve drive, plugged flow and calibration. All of Brooks devices are tested as complete systems to ensure robust and accurate operation and are calibrated to international standards.
