How many secrets do you have in your life that you don't know?

 

With the rapid development of technology, gas flow measurement and control have become the mainstream in industry. But, do you know? Gas measurement and control have been widely used in daily life.
The temperature has warmed up and the spring atmosphere is strong. During the holiday, it's time to drive and take your family out for fun. Today, the flowers in the North Jiushui Scenic Area of Qingdao are in full bloom. We take this as our vacation destination to introduce you to the application of gas measurement and control in daily life.
surface treatment

 

Firstly, driving to the vacation destination, let's talk about the car dashboard. Many cars have leather dashboards, at least they look like leather.

The skin manufactured by a certain company covers the dashboard of a car, giving it a leather appearance. The skin is produced by spraying liquid and some polyurethane into a nickel mold. The combination of quality flow controller and valve forms the foundation of this solution, which can accurately place the external release agent on the surface of the nickel mold.

 

 

Glass coating

 

The front window of a car. In order to control the transparency of glass, make it waterproof, protect it from mechanical and chemical stress, increase scratch resistance and shatter protection, thermal mass flow controllers are used in coating processes to achieve these functions.

By controlling the gas flow rate of each process, the uniformity of membrane thickness can be improved.

 

Headlight coating

In the early 1980s, new problems arose when introducing polycarbonate as a substitute for headlight glass. The headlights are easily affected by harsh environments. Due to its position at the front of the car, key parameters that affect service life and performance are weather, scratches, and wear.
In order to protect the headlights from the influence of these factors, scratch and wear resistant coatings have been developed, which are sprayed onto the headlights by robots, where the flow to the nozzle is controlled by a mass flow controller.

 

Production and production of ice cream

 

 

For most people, ice cream is a classic summer delicacy. However, at the moment you enjoy ice cream, you may not think about how this delicacy is made. To make ice cream, aeration during the production process is crucial.
This is because air accounts for 30% to 50% of the total amount of ice cream. Higher aeration will produce more delicious and smoother ice cream. The side effect of adding air to ice cream is that it melts more easily.
Therefore, in order to obtain the optimal structure of ice cream, it is important to have a stable inlet air flow and a constant cream/air ratio during the production process. This can be achieved by using a mass flow controller.

 

 

What is the relationship between ice cream and mass flow meter?

Ice cream contains many different ingredients, such as fat, sugar, milk solids, emulsifiers, seasonings, and sometimes colorants. But there is another major component that you may not have thought of, air. Ice cream is made by freezing and simultaneously mixing air into the ingredients. So why is air so important?

 

If you have ever had a bowl of ice cream that melted and then refrozen before eating, the taste may not be as good as before. Additionally, if you melt a box of ice cream under the hot sun, the volume of the ice cream will decrease. Air accounts for 30% to 50% of the total amount of ice cream, therefore, aeration is crucial during the production process.

The amount of air in ice cream (usually referred to as expansion) can affect the taste, texture, and appearance of the finished product. Higher aeration will produce more delicious and smoother ice cream. Another effect of adding air to ice cream is that it melts more easily. Therefore, in order to obtain the optimal structure of ice cream, it is crucial to introduce a stable inlet air flow rate and maintain a constant cream/air ratio during the production process. This can be achieved by using a mass flow controller.

The process of beating ice cream into shape

To ensure the correct consistency and structure of the complete ice cream, cream must contain the correct bubble ratio and composition. Therefore, the aerator manufacturer uses a mass flow controller to add a precise amount of air to the cooled mixer. This quality flow controller will ensure that the continuous delivery of air and cream flow is proportional. Regardless of any possible backend pressure changes, the mass flow controller must be able to maintain its performance. Sometimes, check valves are installed downstream of the mass flow controller. If the inlet pressure drops, this valve will prevent ice from flowing back into the instrument. A pressure gauge can also be used to detect inlet pressure.

 

LED lighting

 

Driving home at night, lighting control technology is used in outdoor road lighting. When there is a high flow of people and vehicles, the street lights operate at full power. When there is still night and low flow of people and vehicles, half power operation is implemented, that is, dual power street light lighting is implemented to achieve energy-saving effects. With the development of LED light source technology, the improvement of efficiency, and the decrease in price, it is easier to control, drive, and dimming, providing great possibilities for energy-saving lighting. Underground large spaces, tunnels, and subway stations in cities such as Beijing, Shenzhen, and Shanghai have been newly built or renovated, and LED lighting is directly used for lighting. Intelligent control systems are used to adjust lighting according to different time periods, saving energy; Intelligent perception of human presence and automatic dimming based on human behavior in office and other spaces, meeting the lighting needs of different people and creating a comfortable and energy-saving lighting environment.

 

 

LED works through a phenomenon called electroluminescence, which is the emission of light from a semiconductor (diode) under the influence of an electric field. For example, by applying semiconductor materials such as gallium arsenide phosphide, red, orange, and yellow light-emitting diodes can be manufactured. Among them, quality flow control also plays a role.

 

I have already talked so much, have you gained more understanding of quality flow control?
