Gas emission specialist FluxSense, based in Gothenburg, Sweden, developed as a spin-off company from Chalmers University of Technology in 2001 and uses unique technology to measure emissions. FluxSense mobile and stationary measurement centers are complex facilities with high demands of reliability for their technical solutions. FluxSense has chosen Recab’s products and services to ensure reliable industrial computers for their applications.
Customer case – FluxSense: Industrial computers from Recab to measure emissions
The importance of knowledge of gas emissions. Back in 2001, FluxSense AB started off as a spin-off company from Chalmers University of Technology in Gothenburg on the Swedish west coast. They wanted to provide the ability to execute reliable diffuse emission measurements for the petroleum and petrochemical industry. Since the start they have operated in close partnership with Chalmers University of Technology. The CEO still works part time as a professor at the university and most of their eight employees in Sweden are former postgraduates.
Increasing regulations to improve environmental health
Gas emissions from anthropogenic (man-made) and biogenic (natural) sources contribute to a wide range of environmental problems. Some examples are climate change, ozone depletion, air pollution, photochemical smog, acidification and eutrophication. Increasing regulations, regulatory oversight, and efforts to improve environmental health have made measurements of emission from production facilities a standard in Europe (CEN). With The Paris Agreement regulations and requirements for proper measurements are spreading across the globe.
Knowledge about the emissions and concentrations of the gases leaving industries are crucial for efficient regulations and abatement measures. Diffuse (non-channeled) emissions from large facilities have, historically, been expensive, troublesome if even possible to measure. This has led to idealized calculations based on models and estimations. Which leads to results far from correct due to inaccurate input of data and algorithms.
The techniques for measure emissions
FluxSense AB is the sole licensee for the Solar Occultation Flux (SOF [Technologoy:SOF]) technique and have developed other techniques as well. The SOF technique was developed at Chalmers University. When the requests for usage of the technique grew the company was founded. The technique uses infra-red lights and through optical spectroscopy they study how different gas emissions changes the color of the sunlight.
Emission Quantification, Leak Search, Concentration Mapping, and Air Quality Monitoring
FluxSense AB can therethrough measure the amounts of gas emissions leaving a facility. They can also measure what type of gases the facility is leaking or identify previously unknown gas leaks. Their solution focuses on mainly four services, Emission Quantification, Leak Search, Concentration Mapping, and Air Quality Monitoring.
“In addition of receiving numbers of their emissions in kilograms/hour, which is of interest for both the industries themselves and the authorities, our customers learn their facility and we can find leakages they didn’t know they had. Leakages that can result in a large part of their total emissions.” Oscar Isoz at FluxSense says.
In the beginning, FluxSense AB solely offered services to help measure emissions such as hydrocarbons from industries. During the past two of years, they have expanded their business and developed their solutions to be able to provide their customers with both mobile (customer controlled) and stationary (remotely controlled by FluxSense AB) measurement centers.
High demands for industrial computers
For the first measurement systems they sold they used laptops. The laptops were moved in and out of the cars, a solution that was ineffective and unreliable. Since the measurement system is a complicated system in itself, there is no place for the computers to be a factor of error. Because of this FluxSense started looking into using industrial computers instead. This is when they came in contact with Recab.
– “We needed two simple, yet very reliable computers that could process and conduct these measurements within our mobile and our stationary solutions, Samuel Brohede at FluxSense says. “It is of the highest importance that the computers are able to make the measurements at all times or at the programmed time. If the computers fail the measurements fail and become unreliable, which defeats the whole purpose.”
The mobile solutions must be user-friendly
The demand for a reliable product is high both for the mobile and the stationary solutions. The computers must be able to run the systems and store measurement data. The mobile solutions must be user-friendly for the customers and easily operated. The computers in the stationary solutions operates twenty-four hours a day. They must be able to process the data and deliver reliable numbers at all times. The computers have high demands of being rugged and durable as well.
-“Both sun and wind conditions are essential to be able to perform some of our measurement techniques” Brohede says. “Depending on the weather our possible measurement days, or even hours, can be very limited. Therefore, it is absolute necessary that the computers work whenever they are needed.”
Industrial computers with higher operational reliability
The industrial computers have higher operational reliability. are rugged to endure stress from vibrations and wide ranges of operational temperatures. Another advantage is that the modules aren’t changed as often as commercial computers. This ensures that FluxSense can assist their customers and provide them with support, and if needed spare parts, easily.
-“We think the cooperation with Recab has worked really, really well.” Oscar Isoz says “As soon as we have had a question, we have received a detailed response and have received a lot of help throughout the years. We feel like we did the right choice when choosing you as a supplier two years ago. There are many industrial computers that malfunctions, but these have worked very well so far.”

FluxSense view of their future for measure emissions
The company have since the beginning conducted well over 100 measurement campaigns of industrial and agricultural emissions in Europe, America and Asia. The main office remains in Sweden and FluxSense employees travel all over the world to assist their customers. They have opened up a branch called FluxSense Incorporated on the west coast in the US with two employees stationed there. Since then their business opportunities in the US have grown to be equal if not larger than in Sweden.
-“As of now we work mainly with the authorities in the US, but with the current change of view of the environment and what needs to be done, we are sure to see the interest of companies self-interest in these types of solutions grow.”Isoz concludes.“We see positively at our future, we have conducted measurements for many years now. The techniques and our company have become established and well known, more requests are coming in.
A large market for these kinds of solutions is East Asia. We have already conducted a couple of measurements in China and hope to expand our business there as well as in the US and Europe. The Paris Agreement and other universal environmental agreements like it puts pressure on the authorities as well as the industries to ensure that they have knowledge of what kinds of emissions they let out into the air and regular tests may become mandatory, we provide an effective solution and are eager to help facilities all over the globe.”

The situation last spring was critical, and the lock down of country boarders was the reason that the support staff at Lämneå weren’t able to travel and give their customers support during the installation of the machine or other needs in person. This made the possibility to connect to the machines remotely from home priceless - Customer support via IIoT - Lämneå Bruk.
Customer support via IIoT – A router made Lämneå Bruk less vulnerable when the Corona pandemic started
A router, that the machine manufacturer Lämneå Bruk uses and mounts in the control cabinet of their machines for the last ten years made Lämneå Bruk less vulnerable when the Corona pandemic struck in the beginning of 2020. The router makes it possible for them to connect to the customers machine remotely and proceed the support and service that the customer has bought.
Lämneå Bruk in Ljusfallshammar, located outside of Finspång – Sweden, about three miles from Norrköping is a modern family business focused on manufacturing of highly automated machines, manufacturing lines and facilities for the wire drawing industry with the whole world as their market field. The company had annual sales of about 160 SEK in the financial year 2019/2020. As much as 95 percent of the manufacturing are exported to 98 countries. In total, there are up to 123 different types of machines sold in Germany, USA, Canada, China, South Korea, Japan and India amongst others. Other countries in Europe also belong to the company’s important export markets. The products manufactured using the machines produced by Lämneå Bruk include welding wire, welding electrodes, springs, tubular wire, nails and screws.
One of the most common and typical products among the wire drawing machines is the drawing machine, which has the task of reducing steel wire from coarse to thin by pulling it, for example from 8 to 3mm. Raw materials are wire rod from suppliers all over the world. Another type of machine is so-called rewind lines. In these, the thread is repackaged to the end customer’s packaging. Even though 60 percent of all machines from Lämneå Bruk are machines for the welding wire industry, machines are also built for, for example, spring wire, reinforcement an staple products.
Lämneå Bruk dates back to the early 18th century when the facory was a foundry. The journey in the wire industry started as early as 1823. Today, the company is owned by the CEO Jonas Hagstedt, whose father bought the company in the late 1950s. About 50 employees include designers, automation technicians, programmers, machine fitters in electricity and mechanics, cnc operators, welders, painters, support staff and administrators in logistics among other things. You basically have all the professions that enable Lämneå Bruk to produce everything from home.
Lämneå Bruk have control over the entire production chain
-Lämneå Bruk are able to manufacture a wide range of technically advanced machines for different types of wire, from small single machines to complete lines. Each machine is unique and each customer has special requirements for their facility. Lämneå Bruk build what the customer request and transform ideas into entire machine system solutions that are both user- and maintenance-friendly, says Jonas Hagstedt, CEO and owner when he comes in and visit the magazine Automation, which visited the factory in September 2020.
-We are actually quite alone on the market here in Europe, with just a few competitors. We have control over the entire production chain, and we take responsibility for all parts of the machine. Electrical design, programming, manufacturing of the machine and control cabinets. Everything is assembled on site here in Sweden. We live up to our slogan: “A passion for service”. We are proud to be able to offer excellent customer service before, during and after sales, Jonas Hagstedt emphasizes.
The company is well advanced in the technology. From order to finished machine, it takes between two and six months before the machine can be shipped to the customer. Often together with staff to ensure that the installation goes well and that the staff at the customer company receive good training and support right from the start.
-The customer can decide a lot about what his machine will look like, says Peder Helgesson, automation manager at Lämneå Bruk, who guides the magazine Automation through the facility.
-The customer can make different choices regarding components, mechanical and electrical design and the color of the machine. But we try to standardize as much as possible and therefore the machines are modular as far as possible. We use ready-made well-integrated complete solutions from our subcontractors with control and drive technology that also have integrated safety and energy regeneration.
Technics are today used in over 450 machines across the globe
Lämneå Bruk uses different control systems for their machines depending on the wishes of the customer in accordance with the technology they themselves use in their factory. Generally Siemens controls the machines that are exported to European countries and accounts for most of the solutions (ca. 60-70 percent). Allen-Bradley is used in what is sent to the US (30 percent) and Mitsubishi is mostly used on the East Asian markets including China and Japan. A router is mounted in the control cabinet in the machine or machine line to ensure that the suppliers have access to support and service remotely.
This is where Lämneå Bruk cooperate with Recab, a Scandinavian company specialized in custom solutions within what they call “from edge to cloud”, as well as embedded computer systems, industrial data communication, sensors, and vision. The cooperation began in 2010 and the technics are today used in over 450 machines across the globe. Before that Lämneå Bruk used another, less practical, solution, a regular modem that you connected to through a phone call.
-When we started up our online support in 1994 most people didn’t have broadband connection, so it was probably the only usable solution, says. Peder Helgesson. He works as an automation manager at Lämneå Bruk but also belongs to the team of eight people (automation technicians) who go out and help the customers with installation and training.
The machine is constantly prepared for connection.
The product consists of a router attached in the control panel of the machine and its task is to mediate the connection between the operator panel that is attached to the machine and make it and the entire network on the machine available to the service technician at Lämneå Bruk. This way, the service technician can troubleshoot the machine as if they were sitting on site in the customer’s facility. There are hundreds of sensors in each machine and a lot can happen during the operation of the machine. Everything from a sensor breaking, that the pneumatics not working because a valve may have broken, a pulse sensor to an engine has stopped working to a mechanical fault that has occurred because the wire fell off and accidently hit some part of the equipment. HMIs are also sensitive things with their touch screens that can break because you may press too hard and too much on the screens while wearing rough work gloves.
– The router connects to the network and further to the central server, which in this case is located in France, says Magnus Unosson, customer responsible at Recab
– The advantage is that it is a secure connection that does not disturb the company’s firewalls since it connects from the inside and out. Software that belongs to the router also handles IP addresses that are there in the background. The customer easily connects to the router with the help of a unique product code key. The solution uses the company’s existing connection to the network. A fixed connection also means that you avoid problems with SIM cards and such. The machine is constantly prepared for connection. When the service is to be done, the customer wants access to new functions on the machine or when various additional programming in the plc is to be done, you connect to the server.
The solution that Recab offers consists of both the hardware, a router from Etic Telecom, as well as the software called m2me. The m2me-solution by Etic is intended for remote maintenance and control of all types of industrial units (plc, hmi, Drive, etc.).
– In these times, during the Corona Crisis, when it has not been possible to travel freely across the world during long periods of times it has been a huge advantage to be able to connect to the customer remotely from home, states Peder Helgesson. Occasionally the customers need extra plc programming and naturally it becomes cheaper when we can do it from here, since it saves us long expensive trips and lots of time. There can be about 50 pages in the operator interface with images and everything. Our machines use different standard modules, but it is common for the customer to want their own adaptions and additions.
This might be Lämneå Bruks largest competitive advantage on the market. That they can deliver machines that are based on standard design but offering a lot of customizations. They also build and develop new machines or functions in direct cooperation with their customers. These machines are completely customized without a standard basic to begin with.

With EasyPay, you can easily drive in and out of a parking area without (a lot of) concern for payment and exceeded parking time - msart reading. A tight cooperation between Recab and Profectum has resulted in a smart solution that eliminates stress when searching for a parking meter, and you will no longer be fined for a couple of extra minutes.
Profectum has a tight cooperation with Recab and Nils Olav Gjørvad on the parking solution within smart reading. – The result is a robust electronics cabinet which can be mounted both indoors and outdoors, he says.
We at Recab are proud to present: easyPay: Parked the challenges for smart reading through collaboration with Recab
The product, which is starting to become well known by many people, is called EasyPay. It is described as a new and modern solution for easy and user-friendly parking. – There will be no need for tickets, fines and barriers as this is replaced with smart technology, says the managing director of Profectum AS, Lars Kaasin.
The parking time starts and stops by advanced camera technology, and the payment is automatic. Lars Kaasin tells that Profectum is growing fast, and the solution is used, for example, in parking houses, shopping malls and amusement parks. The company has become a real competitor to the traditional parking companies.
– Recab is our collaborator on machinery, and together we have developed solidly built centrals that can handle a vast number of cars arriving to park, Kaasin says. He emphasizes the cooperation with Nils Olav Gjørvad at Recab. – He has given us valuable support with choosing components, testing and implementation of the project, Kaasin explains.
Found the right knowledge
– We got into contact with Recab since they are distributor of a unit which we wanted to use in our own centrals. We soon discovered that Recab has knowledge and experience from similar project, and that they therefore could be a valuable collaborator for developing our solution, Kaasin says.
Stabile and scalable
– The process started with mapping and choosing components for designing the central, testing and making a prototype. Eventually we found the final solution, and now we have a stable and scalable product which is easy to maintain, he continues. The core of the system is an industrial PC without a fan, and with an extended temperature range. According to Gjørvad, the PC is a Nuvo 5002LP from Neousys Technology, with a sixth generation Core i7 processor which corresponds to a strong stationary PC, but this is a more robust and maintenance free version.
Nuvo-5002LP/5006LP is the low-profile version of Nuvo-5000 family. It features a low-profile chassis, which reduces its height to 77 mm, and remains extraordinary 25°C to 70°C operating temperature. For those demanding varied computing power, Nuvo-5002LP/5006LP supports socket-type CPU for flexible CPU installation.
– All video processing and number plate recognition is on this platform, Gjørvad explains. – Everything is designed according to Profectum´s specifications, and we have made all the necessary switches (including fiber options), a 4G modem, and we have defined the power supply, UPS, as well as an emergency power battery, he further explains.
From camera to sky
The central communicates with ANPR cameras which register the number plates, plus Profectum´s sky solution for further processing.
– For us, it is critical that all components register every parking, and the chosen components in the centrals reflect this, Kaasin says. He emphasizes that they have chosen high quality solutions that gives redundancy to both the network and power supply. In this work, he describes Recab as an important and valuable supporter.
One hundred percent Norwegian
Profectum delivers all the software, and the solutions are finished at Topro. When the cabinets have been configurated at Recab´s filial at Eggemoen near Hønefoss, they are sent directly to the users, where they are connected to the power system and cameras.
A good environment for product development
Recab´s main Norwegian office is at Hamar, but the company has chosen to keep the Eggemoen office for several reasons. – Here we are in the thick of things regarding product development. You will find, for example, Tronrud Engineering, which is both a customer, supplier and collaborator on a lot of projects. You will also find the mechanic supplier HG-Mek, Prox/Flir, and Norsk Titanium, Gjørvad proudly informs. The Hamar department has just moved to new locations, and Elektronikk will come back to this in a later issue.
To Profectum, the solution means more competitiveness and possibilities of growth. – For us, it is important to have control at all stages of our solutions. We develop all software ourselves, and we will have the same control over the machinery in the centrals, Kaasin says. – Through our cooperation with Recab, we have gained full control of the actual components, and none of the centrals has broken down so far!

The surveying and positioning company iSurvey needed to develop a new advanced module for its iSafe positioning system. RECAB took on the challenge. iSurvey is a dynamic company providing a range of advanced services for seabed surveying and positioning for offshore installations and ships. For one of iSurvey’s systems, there was a need to develop a more compact, robust modular support unit including positioning and communications electronics.
“The requirements we were facing were fairly tough,” says Nils Olav Gjørvad at RECAB. “We’re talking about a solution consisting of several units that had to be integrated into one robust module. Not only that, but the size and surface area requirements were rigorous. And it had to reuse the UHF radio and GPS module from the existing solution.”
Taking on the iSurvey challenge – Develop a new advanced module for its iSafe positioning system
The surveying and positioning company iSurvey was looking for a “nutcracker” to crack the tough nut of developing a new module for its iSafe positioning system. Recab took on the challenge.
iSurvey is a dynamic company providing a range of advanced services for seabed surveying and positioning of offshore installations and ships. For one of its systems, the anchor management system iSafe, there was a need to develop a more compact, robust modular support unit including positioning and communications electronics.
Shrink the module
The requirements we were facing were fairly tough, says Nils Olav Gjørvad at RECAB. – We’re talking about a solution consisting of several units that had to be integrated into one robust module. Not only that, but the size and surface area requirements were rigorous. And it had to reuse the UHF radio and GPS module from the existing solution.
First, to see whether it was even possible to develop the desired product, RECAB carried out a feasibility study in cooperation with the Danish division of the company. – Our colleague Brian Axbøg did much of the 3D design of the solution, says Gjørvad. – It was important to do this early on to make sure all the components would fit. We also had to deal with the heat and EMC challenges you face in a densely packed cabinet containing processor cards, a GPS module, a UHF module and diplexer.
Had to develop heat spreader
Choosing the processor turned out to be a challenge too, since there isn’t much cooling inside the box, he says. Initially RECAB was looking at an Intel Atom-based card to keep power consumption down, but it didn’t deliver optimal performance. Instead, they went with a third generation Core i3 processor, deciding it was better to take the trouble of developing solutions for getting the heat away from the processors. – It took a lot of R&D to get it to work, says Gjørvad. We developed a special aluminum heat spreader to conduct the heat out to the chassis. The solution we ended up with is specified for use at up to 60°C ambient temperature. We also had to design a brand new power supply unit in order to fit the space and provide proper outlets.
The mechanical design of the unit is a separate challenge. The chassis and its mounting bracket (which can be collapsed when not in use) are designed to be easy to move and set up wherever needed. – The mounting process had to be as simple as possible. The unit can either be attached directly to the equipment it will be used with or placed in a rack, says Gjørvad. The mechanism was developed by a Danish company with expertise in products for maritime environments, and the unit is IP65-rated.
The solution is a support system intended for use in positioning drilling rigs and ships during operations such as anchoring, says Gjørvad. – Typically you have a positioning system aboard the oil rig and an iSafe system on each supply boat. These units communicate by radio in the UHF range, and provide positioning data that is adequate for use by the control systems of iSurvey.
Challenges – Develop a new advanced module for its iSafe positioning system
I think we’ve done a good job of meeting the technical challenges, says Gjørvad. One of the biggest challenges otherwise was keeping track of all the details. Good project management ended up being extremely important. The products have now been deployed and are field proven, robust and stable in operation in the North Sea. And iSurvey is satisfied with our implementation!
Developing a maritime unit for a positioning system:
– The requirements we were facing were fairly tough, says Nils Olav Gjørvad of RECAB.
The industrial design of the solution was an interactive process engaging both iSurvey and RECAB. The 3D design and implementation were done by RECAB’s Danish division. The positioning and communications module is designed so it can be moved into the field and installed quickly and easily.
The iSurvey Group provides a range of services in the area of surveying and installation of offshore projects, from data collection and seabed surveying to positioning and management of multiple ships, underwater positioning, anchor management, cable installation, and ROV remote control, to mention a few. The Group is based in Billingstad, outside Oslo, and has a division in Singapore.
