During the past months of (partly) lockdown, most people have worked from their home offices. Maybe you as well? Now summer has started and most of you are looking forward to finally leave your homes, at least I do! Some restrictions are a little bit released in Europe which makes this possible as well. However, I can image that you still prefer to go on vacation in your own country. My favorite way of enjoying my vacation is camping!
When I travel around, I always come across a lot of applications in which our flow meters play a role. Let me guide you through some mainstream products you often see at a camping site, and the involvement of mass flow controllers in their production processes.
There is a big chance that you will travel to your holiday destination by car. In the manufacturing process of many car parts, flow meters have played a role. Let’s start with the dashboard of your car. Many cars have a leather dashboard; at least, it looks like leather. A major company manufactures ‘skin’ that covers a car's dashboard, to give it this ‘leather look’. The skin is produced by spraying liquid, coloured polyurethane into a nickel mould. A Coriolis mass flow controller combined with a valve forms the basis of this solution to accurately supply external release agent to the nickel mould surface. Read the application story about, how this 'skin' is being manufactured.
But also the foam within the dashboard is manufactured by using Bronkhorst products. To create foam, a gas is added to a mixture, containing acrylonitrile-butadiene-styrene (ABS) or polyvinyl chloride (PVC), to give it the right volume. Too much gas will make the foam unstable, too little and you’ll get a heavy solid block. Therefore, it is utterly important that the correct amount of gas is added with an accurate gas flow controller.
However, surface treatment is not only applicable for glass and dashboards. If you have experience with camping, you will be familiar with how fierce the summer weather sometimes can be. The awning of your caravan needs to be water repellent - this also applies to your raincoat - to sustain the heavy rainfall now and then. To make fabrics and textiles hydrophobic, Empa - a research institute of the ETH Domain, applies plasma polymerisation to deposit thin, nanoscale layers on top of fabrics and fibers. For this, they are using a Controlled Evaporation and Mixing system, in short a CEM system. In one of our previous blogs ‘Hydrophobic coating, the answer to exercising in the rain’ you can read about this application.
Bronkhorst is also involved with many smaller attributes you will encounter on a camping site. Most people still enjoy the comfort of gas for heating or cooking on the stove. With gas we are also able to fire up the barbecue really fast, in comparison to the old-fashioned briquettes that are sometimes hard to ignite. When gas escapes from a pressurized cylinder, you’ll recognize this from its penetrating scent. However, like Sandra Wassink stated in her blog “How mass flow controllers make our gas smell”, natural gas is odorless. By controlled supply of odorants like Tetrahydrothiophene (THT) or Mecaptan with a mass flow controller, the scent is added to the natural gas on purpose.
Let’s stay with the topic scent for a moment. For when we want to decrease the number of mosquitos in our surroundings, we often enlighten a citronella candle when we are getting tired of using the flyswatter. With the CORI-FILL dosing technology, Bronkhorst offers an easy-to-use setup to dose fragrances, like citronella, in candles. The addition of fragrance to a candle should be carefully monitored to ensure the candle burns cleanly and safely. To read in more detail about the role of flow meters in the production process the production of scented candles, please read the blog of Graham Todd about adding fragrances to candles.
Although a candle can bring much light to your surroundings, you won’t take a candle with you when you go to the camping toilets at night. Instead you will use a flashlight of course. The working principle of the LED (Light Emitting Diode) inside this flashlight is a technology where Bronkhorst flow meters play a role. LED works via the phenomenon called electroluminescence, which is the emission of light from a semiconductor (diode) under the influence of an electric field. By applying a semiconducting material like Gallium arsenide phosphide for instance, the manufacturing of red, orange and yellow light emitting diodes is possible. Flow meters play a role in the manufacturing process of these LEDs.
I already told you so much, but frankly, just a tiny bit of all the camping applications our flow meters are involved at. Hopefully you got some more insights on the importance of Bronkhorst in many industries, also when you go camping.

A very important aspect of camping life is food and beverage. Our industry specialist explains the importance of Bronkhorst in this industry.
Did you know that natural gas is odorless by nature? Flow controllers combined with a pump are used to dose THT into natural gas, giving it a penetrating scent to act as a warning agent.
