Level Indicator and Its Uses
Author: SHIR
Level indicators are level measurement devices used to measure the height of liquid or solid in its containing vessel. The two most common types are the magnetic level indicator and the float and board level indicator.
The magnetic level indicator is used to measure fluids and consists of a floatable device that is able to float in high and low density fluids. These indicators can often withstand severe environmental conditions. It comprises a permanent magnet that is sealed within a float, whose rise and fall opens and closes the switch. The most important factor that must be kept in mind while selecting the appropriate magnetic indicator is the magnetic field. The stronger the magnetic field, the more efficient the instrument.
The magnetic indicator is fitted with a precision manufactured float which has internal magnets and flex rings. Moreover, the flag or shuttle type indicator with the stainless steel scale can correctly measure height, volume or percentage of level. These indicators are used in water heaters, industrial boilers, oil/water separators, flash drums, surge tanks, gas chillers, etc.
The float and board level indicators are also used to measure fluid levels in industries. The float is particularly important because of its buoyancy, structural design, volume displacement, etc. A regular float and board indicator would consist of a float, a dustproof pulley housing, pointer cradle with nylon and 150 mm screen printed aluminium scale. These indicators work on the principle of buoyancy. They find application in over ground and overhead storage tanks, and are also used for the measurement of petroleum products like furnace oil, diesel, lube oil, etc. The non-corroding aluminium board with brightly painted scale projects the measurement clearly. This device is easy to handle and also extremely portable.
Some other types of level indicators include:
Tubular
Reflex
Transparent
Welded Pad type
Slight Flow
These devices are very useful for industrial use, and are easily available in the market as well as online. It is, however, important to have full knowledge of the type of matter to be measured and the most appropriate level indicator for it. These indicators are scientifically designed, and resist wear and tear that is likely to take place over time. Level monitoring and automatic movement of fluids is an important concern in most large-scale production units, be it in the health, food or petroleum industry. They are, however, only one part of the larger variety of level measurement instrumentation.

So the other day I decided to try out this audio amplifier kit. The idea was to end up with a fully functioning two channel amp, with indicator LEDs, a volume control and a standby switch.
The finished article configures at two times 38W. It’s linked to the SparkFun STA540 and the whole lot needed to be soldered – there wasn’t any pre-soldering done on the PCB. As such I would say that it was reasonably challenging, certainly the kind of thing that you’d expect to spend some time on due to the sheer number of steps involved.
I won’t bother with an exhaustive list of parts as you can get one by having a look at the audio amplifier kit’s home page. Instead I’ll try to recount how I put the thing together. I will note before I start though that the audio amplifier kit does include the STA540 amplifier, so don’t go out and buy another one by mistake.
So first I put the amp on the board, and installed three resistors (1K), followed by five 10K resistors, two 47K resistors and two 100K resistors. In all cases I made sure the resistors were pushed all the way through the board and firmly soldered in place. When the solder is dry you can clip and trim it to make everything neat.
Then I installed the capacitors for the audio amplifier kit, and the standby switch. There are a few different capacitors that you need to put in. The standby switch has no polarity sensitivity.
The LEDs in the audio amplifier kit, on the other hand, do. Make sure you install them correctly or they won’t work. Remember – a flat bit on your LED, or one wire shorter than the other, are both indicative of the negative terminal.
After that came five screw terminals. Then the potentiometers. After that, the STA540 amplifier chip and the heat sink. As you’d expect, the amp chip and the heat sink were the most critical bit of the audio amplifier kit so I took my time. First applying heat sink compound to both parts and then securing them half tight with the bolt. Once you get the whole thing onto the board, the slack is taken up by the positioning of the heat sink and the amp in their holes – so you don’t want them mated too tight at first.
After putting in the stand offs and the screws, the audio amplifier kit was complete and all it needed was a quick test. That’s easy enough to do. Turn it on, move the potentiometers all the way round and measure the resistance. It should be around 9 and 10k on the left and right channels.
The Growth of 3D Printing Technology
Author: zohar ohayun
The world today is at the cusp of a new technology that can change the way products are manufactured- 3D printing. The last time the world witnessed a new method of mass production, it triggered the industrial revolution, which influenced the modern world economy in many ways. 3D printing is a cheap and easy way to create single items, and price to print items on a large scale is also much smaller. 3D printing is has already made a profound impact in companies across the world. Here is a quick look at how this technology works:
How 3D printing Works
3D printing works by using a virtual 3D file made on a computer- it is as simple as that. Like any regular paper printer, you just need to click on the print option on the computer, and the 3D printer comes to life. The machine either deposits material through a nozzle or solidifies and binds thin layers of plastic laid on top of each other using an adhesive. In other words, the 3D product is built by progressively adding material to it, instead of the traditional method of carving or cutting out the model. It is for this reason that 3D printing is often referred to as additive manufacturing. Of course, plastic is not the only material used by 3D printers. These machines can use several kinds of materials like resins and even metals, and they can provide models that are precise to a tenth of a millimeter.
Advantages of 3D Printing
3D printing offers several benefits over conventional forms of manufacturing. 3D printers can cut production costs by doing away with the need for production lines. Moreover, this technology also curbs the amount of waste generated during the production process. Many 3D printers require only a small fraction of the amount of material to create precise models. In addition to this, 3D printing technology allows you to create certain shapes and parts that are not possible through conventional techniques. This results in better and more efficient designs for products being turned into reality, like aircraft wings.
The Effects of 3D Printing on the Current Manufacturing Scenario
As mentioned above, 3D printing can significantly change the manufacturing industry. It can limit the barriers of entry for manufacturing companies because there is no longer a need for large and complex production lines. All you need to do is design the model on your computer and then turn it into a real object. You can also print a prototype model, test it for any discrepancies, and then print a modified version. This can be very useful for start-up companies as well as investors since creating and trying out new products can be less expensive and safer.
Some people feel that the impact of 3D printing will not just be felt in separate manufacturing companies, but in the function of the industry itself. 3D printing has the potential to change a lot of aspects of industrialization, because there will be no need to create large factories. 3D printing has not yet made the impact it can make, but it is clear that the time will soon come.
