Balometer Calibration: Why It Matters

Balometer Calibration

Before diving into calibration and why it matters, let’s first understand what a balometer is and why it’s essential. In the world of HVAC (Heating, Ventilation, and Air Conditioning) and indoor air quality management, precision is key. Accurate airflow measurements are crucial for maintaining a comfortable, energy-efficient environment and diagnosing system performance issues.

What are Balometers?

Balometers, commonly known as Flow Capture Hoods, play a pivotal role in balancing indoor airflows. Entrusted with the crucial task of measuring and regulating airflow within our buildings, these instruments are the go-to tools for HVAC technicians, building engineers, and indoor air quality professionals. They help ensure that air distribution systems are functioning optimally, preventing issues such as uneven heating or cooling, inadequate ventilation, and poor air quality. To maintain the accuracy and reliability of balometer readings, regular calibration is essential.

Why is calibration important?

Calibration is important because it helps ensure accurate measurements, and accurate measurements are foundational to the quality, safety and innovation of most products and services we use and rely on every day. If you look around, most of what we see was produced within tight measurement specifications assured by calibration.

When it comes to balometers, precision is paramount. These devices are responsible for gauging airflow rates with accuracy, ensuring that ventilation systems operate at their best. Inconsistent or inaccurate readings could lead to imbalanced airflow, which, in turn, affects indoor air quality, energy efficiency, and overall comfort.

Here’s why calibration is important:

  • Precise airflow measurements are crucial for efficient HVAC systems.
  • Regular calibration ensures compliance with regulations, promoting health and safety.
  • Accurate airflow measurements support energy-efficient HVAC operation.
  • Calibration serves as preventative maintenance, minimizing downtime and extending equipment lifespan.
  • Reliable data from calibrated balometers supports effective system management.

Summary

In the world of indoor air quality and building performance, Balometers are indispensable tools. They ensure that the air we breathe is clean and that our indoor spaces are comfortable and safe. But their effectiveness relies on their accuracy, which is maintained through regular calibration.

So, the next time you breathe in clean, comfortable air indoors, remember that behind the scenes, balometers and their calibration are silently working to make it all possible. In the world of HVAC, where precise airflow measurements are vital for maintaining comfort and energy efficiency, regular balometer calibration is not a luxury; it is a necessity.

In response to the growing emphasis on air quality within the built environment, BSRIA is pleased to announce an expansion of its service portfolio, with the introduction of a cutting-edge airflow Calibration Rig at its North facility in Preston, Lancashire. This is alongside the existing rig at BSRIA Bracknell, both rigs are officially endorsed by UKAS (United Kingdom Accreditation Service).

Servitisation, Smart Systems and Connectivity – What’s next for instrumentation?

There are many buzzwords associated with the multitude of new developments in today’s technological world, and the use of terms like Smart Instrumentation, The Internet of Things (IoT), Big Data, and Servitisation are becoming increasingly common. Whilst we may think that we are familiar with these descriptors there is sometimes a disconnect with what they mean to the industries where they apply.

BSRIA is uniquely placed to be at the forefront of the use and application of technological innovation especially within the building services industry. BSRIA’s vision is to be leaders for information, knowledge and improvement for the built environment; with an aim of ‘making buildings better’, so concepts such as the BSRIA Business-Focused Maintenance (BFM) methodology fit this remit and have become increasingly relevant as technology has advanced.

Today’s engineers can now use a wide variety of instrumentation that can be considered ‘smart’. However not all smart instruments are created equal and to be truly smart the monitoring data must be connected to the Internet of Things (IoT), generating data that is uploaded and analysed either by a human operative or a software application. This can be used in preventative maintenance planning, helping to move away from planned scheduled maintenance schedules which are often expensive and unreliable in identifying faults and potential failures. Some of the most widely used monitoring methods include ultrasonic flow meters, temperature monitors, humidity monitors, power meters and process emissions analysers. These instruments and others are indispensable tools for engineers, they provide a non-invasive, user-friendly and cost-effective solution to maintenance testing which can be used as part of a smart system of monitoring.

A smart IoT instrument must be linked to the internet through a hub or router. The continuing development of smart technology and the IoT in the instrumentation sector means that something called servitisation is becoming increasingly relevant in the way that today’s building services sector customer offerings are created and marketed.

The concept of servitisation was first discussed by Vandermerwe & Rada in their 1988 paper; ‘Servitisation of business: Adding value by adding services’, published in the European Management Journal. The Servitisation of products involves a strategy of adding value by adding services to products or even replacing a product with a service package. For example, supplying an HVAC system and adding various levels of service, additional features and product support. Customers can be offered a choice of options for a product ranging from supply of the basic physical parts of the system, right up to a complete turnkey solution including all support, monitoring, maintenance and repair. For instrumentation the basic physical unit can be supplied, with additional services including accessories, software, service & calibration and data management being sold as additional options. Data management services are a relatively recent addition to the instrumentation sector, this can include mobile apps, data portals, warehousing & storage and data processing.

The way that servitisation is offered to a customer can be business or even product specific, for example there could be an initial capital expense payment, or the entire cost could be fully included in a subscription or lease type agreement. This helps the customer to manage capital expenditure and the seller to manage their finances by making income streams more consistent and aiding cash flow management. However, it is important to supply products that add value to the performance or create cost savings for a customer, over-specification or ‘over-servitisation’ of smart systems can be pointless, expensive and can lead to loss of customer goodwill.

With the user-friendliness and wealth of applications for smart instruments, you don’t need to be an expert, employ a consultant or have large budgets to get the data you need. We work closely but independently with a wide range of equipment suppliers which means we can provide solutions to meet our customer’s specific needs. We can supply a wide range of smart instruments from entry level units up to state-of-the-art professional cameras and all at an affordable price.

We recognise our client’s needs are time critical and we have equipment available for hire and sale direct from stock or with short lead times. In processes where plant failure can cause down-time that can potentially cost millions of pounds in lost income it is imperative that critical building services must never be disrupted by failure. We pride ourselves on providing fit-for-purpose, user friendly and cost-effective equipment.

At a basic level, an IoT instrument takes a measurement, this data is uploaded to a processing system, the data is analysed and any potential risks or failures are highlighted – this can result in an automated system response (e.g. process change or shut down) and/or an alert to an engineer (email, text, etc.) to highlight the issue for action (e.g. schedule specific maintenance or equipment replacement). The data analysis process is key to effective system operation, it can use Big Data processes to highlight potential problems (i.e. using software to analyse very high volumes of data to identify patterns consistent with potential problems). Artificial Intelligence (AI) software is one of the most recent developments in building control and monitoring technology and is an ideal fit for smart systems, it has the potential to deal with huge volumes of data and identify problems more effectively than human or traditional digital algorithm analysis. AI is a relatively new field and advances in this area are likely to increase at pace over the coming years and impact all aspects of the sector.

The development of smart IoT instrument systems is also driving servitisation by moving the point of value from physical instruments towards the software and data handling. There are many ways in which the building services sector has opportunities to use big data to create value for the customer, including improved information security and enhance physical comfort to increase worker performance. These trends are discussed in detail in the BSRIA publication BG75/2018 Building Services Analytics.

IoT instruments can also be linked to or part of a Building Management System (BMS) and it also fits with the BSRIA Business-Focused Maintenance (BFM) methodology first published in 2004 and updated in 2016 (BFM Guide BG53/2016). BFM plant maintenance requirements can utilise smart instrumentational monitoring and data processing. An aim of BFM is to provide engineers with a methodology for utilising maintenance budgets more effectively, this aligns with the design of smart instrumentation systems and the creation of service offerings. Assets critical to the business are maintained, while other less critical assets are managed as well as possible within the available budget. By assessing and prioritising plant maintenance needs for risks and criticality to the business, engineers and managers can ensure their maintenance effort is resource efficient, focused, cost-effective and increase their resilience to engineering risk.

The way that BMS data is managed and processed is as important as the instrumentation itself, it must be generated and analysed in a format that can be used to create plans and actions that add value, generate efficiencies and create cost savings for the customer. Some of the first digital breakthroughs have been in predictive asset maintenance and real-time monitoring. Digital twin systems where a virtual model of a physical asset is created allow predictive analysis to be performed and can highlight potential failure points more effectively than routine planned monitoring work. However, focus must always be on the key aim of smart systems to simplify processes for the end user, systems should work for the user not the other way around, this applies to the instruments, their control systems and product support.

Technological developments are likely to continue increasing in pace in the coming years and this will impact everyone involved in the sector from operators to supply chain suppliers.

Thermal Imaging Camera Applications in Business Focused Maintenance

Today the modern built environment faces many challenges with organisations expecting the reliability of services to continuously improve with cost savings being made due to reducing maintenance regimes. Down-time can be extremely costly to a business in lost income, therefore mission critical services must not be disrupted by failure. Historically businesses have used generic planned preventative maintenance schedules, maintaining plant in the same way regardless of its level of use and value to the business.

 

Identifying that there was clearly a smarter risk-based approach to maintenance BSRIA published its Business Focused Maintenance (BFM) methodology back in 2004, this was updated in 2016 with the BFM Guide (BG53/2016) which is available from the BSRIA bookshop. BFM provides engineers with a methodology for utilising maintenance budgets more effectively. Assets critical to the business are maintained, while other less critical assets are managed as well as possible within the available budget. By assessing and prioritising plant maintenance needs for risks and criticality to the business, engineers and managers can ensure their maintenance effort is focused, cost-effective and increase their resilience to engineering risk.

 

Typical thermal images of engineering plant used to identify and monitor potential failures

 

BFM plant maintenance requirements will require instrumentational monitoring and one of the most widely used monitoring methods is thermal imaging. This has many applications including showing faults in thermal insulation, electrical installations and mechanical plant. Thermal imaging cameras are indispensable tools for engineers, they provide a non-invasive, user-friendly and cost-effective solution to maintenance testing.

How hard can opening a new office be?

As some of you may or may not be aware, the new BSRIA North site is now open for business.

For organisations opening a new office or site, it should be a time of great anticipation and excitement as the company sets out a new path, but for many they approach this process with fear and trepidation and for those tasked with the job of making it happen, it can potentially be an extremely stressful period of time.  As Project Manager for the setting up of BSRIA North, I thought I would share with you my experiences – the very good, the sometimes bad and the occasional ugly!

This blog was written by June Davis, Business manager of BSRIA North

I will be sharing my experiences and tips on:

  • Identifying and interpreting the business requirements
  • How to determine the must have’s versus the nice to haves
  • The importance of establishing an internal project team – you can’t do this alone!

BUSINESS NEEDS

When establishing the business needs, spend time with colleagues from across the organisation to listen and understand what they would like to see from a new base – what is it about the current environment that works, what doesn’t work so well and what would improve their working environment if only it were possible!

Everyone one I spoke to was really keen to give me their wish lists and as I started to jot their ideas down, some similarities started to emerge, but for some their thoughts varied significantly.    Prioritise the must haves and rationalise the nice to haves and a vision of your new building will start to emerge.

TIP don’t lose those more obscure requests. Whilst on this occasion I couldn’t deliver a building that had an on-site wind turbine, I was able to deliver on the overhead gantry crane!

TIP:  to fulfil everyone’s requirements you would most likely need to commission a bespoke building, so make sure to manage expectations!

Internal Project Team

You can’t succeed on your own so it is imperative that you establish an internal project team.  Working with business managers from across the organisation proved a valuable source of knowledge and support.  Individual managers were allocated areas of responsibility spanning right across the project and each were tasked with identifying what needed to be done , this formed the basis of a project plan.

Example project areas:

·         Property

·         Fit out

·         Process/Systems

·         Health & Safety

·         Quality

·         Marketing

·         People

 

Ensuring the team communicated regularly weekly meetings were held and if on occasion some colleagues were unable to attend it ensured that we kept abreast of developments – or on occasion the lack of!

Select a property

It seems obvious, but finding the right property in the right location and that meets the detailed specification your colleagues have challenged you with can at times feel like finding a needle in a haystack. This is where the word compromise well and truly comes in to play!  Give yourself a sizeable geography in which to search for property – like you, everyone wants it all, so make sure you keep an open mind and research those properties that at first glance you would dismiss as not meeting your criteria.   What you think you need and what you finally agree is ‘the one’ may well prove to be completely different – it did for us!

TIP The more sites I visited the more ideas I collected as to what could work and might be achieved!

 TIP:  Draw up a short list of buildings and compare them to your must have list – is there a property that is starting to lead the way?

TIP:  Engage one of your project team to come with you to revisit your top properties – they will bring a new perspective to things.

TIPIf possible, establish a good relationship with the previous tenant, in our experience they were really helpful in providing information about the building, how it operated and its history!

The legal process can take quite some time, it was certainly longer than we had anticipated; but don’t underestimate this vital element of the journey. It is critically important that your future building has the correct legal foundations in place, so ensure you seek good advice.

With the legal aspects complete we gained possession of the building and we all got a much-needed motivation boost! The project team visited the site to design the layout and agree what renovations needed to be made.  The vision was taking shape!

Renovations and installations!

Be ready – This is an extremely busy period.  Obtaining quotes, liaising with contractors, arranging building services are just a handful of the tasks at hand. I found that having someone local to the site with good local knowledge is hugely helpful.  Access can be required at various times of the day and sometimes night but with the building not yet fully functional requires a lot of coming and goings to site.   Ensure the alarm systems are serviced and activated and site security implemented.

TIPTake your readings!  Ensure you capture the utility readings on day one and contact the associated providers to inform them you are the new tenants submitting the readings.  This should be a straightforward exercise I can assure you it isn’t, so be warned!

 

For those who may be undertaking a similar process either now or in the future, I wish you every success.  My recommendation is to ensure you appoint the right person to lead the project, a person who loves to do detail, enjoys multi-taking, doesn’t mind getting their hands (very) dirty, and has the patience of a saint and most importantly a good sense of humour!

BSRIA North is proud of what has been achieved and we forward to welcoming you through our doors – please visit us any time!

Infrared technology protecting against Ebola

This blog was written by Alan Gilbert, General Manager of BSRIA Instrument Solutions

This blog was written by Alan Gilbert, General Manager of BSRIA Instrument Solutions

As Heathrow and many other international airports start to employ screening procedures in the fight against the spread of Ebola, BSRIA Instrument Solutions General Manager Alan Gilbert discusses how the technology will be used.

Q. What technology will be used at Heathrow?

Heathrow will be using IR (Infrared) spot type thermometers to take skin temperature of people that have been identified as coming from areas affected by the current Ebola outbreak. These thermometers can detect skin temperature at a distance, which in this application means there is no direct contact between passengers being screened and the instrument being used.

Q. A number of international airports are starting to use thermal imaging camera to screen for the Ebola virus, why is that?

Although there is a low risk of catching Ebola by sharing a plane with an infected person Ebola is a particularly virulent virus and nations and airlines are acting responsibly by identifying any infected travellers prior to boarding the plane or entry into a country. The use of thermal imaging cameras is a cost effective unobtrusive means of detection to screening a large volume of travellers.

Q. Why use thermal imaging cameras?

Thermal Imaging cameras are used to identify and measure the amount of heat that any object produces and emits, this includes people. The thermal imaging equipment used is able to identify the temperature of a large number people simultaneously and with processing software they can identify quick any individuals with potentially a higher body temperature.

Q. What will the thermal image show?

It depends on the technology which is being, but in general terms the thermal image will show that an individual has a higher than normal body temperature and further testing and questioning is needed.

Q. Has thermal imaging been used before?

Yes, in the past when we had a SARS outbreak some high tech thermal imaging cameras were used to identify individuals with increased Thermal image crowdtemperature through an individual’s sinus tracts. Cameras were used around the world in this application as a tool to reduce the spread of the disease and to quick spot individuals who may be at risk from infection.

Q. Which technology is better for screening?

Both thermal imaging cameras and IR thermometers are equally appropriate for use in screening as both technologies will identify passengers who are emitting a higher temperature, this will then allow the authorities to identify passengers who need to undergo further medical examinations.

Q. What happens if somebody is stopped as a result of the screening?

There will be a medical team at the airport who will quarantine the individual and undertake a further medical examination, this will involve undertaking a blood test to allow a proper diagnosis to be made.

Q. If you get stopped as a result of the screening does it mean you are suffering from Ebola?

Not necessarily, you could have no more than a common cold or an upset stomach, conversely somebody with Ebola may be in the incubation period of the disease and as a result not show up as being infected as a result of the screening, due to the numbers of people travelling it would not be practicable to undertake full medical examinations on all travellers, so using thermal imaging cameras is considered to be the best method for undertaking mass screening on travellers.
