FLOWMETERS FLOW – Variable Area Flowmeters Flowmeters in life often are called counters, gauges and rotameter. Most often used as flow meters and water heating, are installed in homes for the precise calculation of hot and cold water, as well as the consumption of heat in the cold period. Anyone who has once fixed his meter, he knows that the savings from such a counter is enormous. By the way, the flowmeter is sold completely affordable price to every buyer. Just flowmeters are used in wine, alcohol, distillery and other industries. Constant differential pressure flow meters and rotameters used to measure expenses and net flows of homogeneous low contaminated liquids and gases flowing. pipeline and not subject to significant fluctuations. Rotameter is a long tapered tube set vertically, along which the action moving upward flow moves to float.

The float moves up until the area of the annular opening between the float and the inner surface of the conical tube is not reach a size at which the pressure drop on both sides of the float becomes equal to the settlement. At the same time acting on the float forces are balanced, and the float is set at a height compatible specific value or scale of the flow. The principle of flow meters based on the dependence of movement of the body that is in flux and dynamic pressure of the receiving stream flowing around it, the flow rate substance. Widespread metering the flow is constant differential pressure flow meters – rotameters, float and piston. The principle of constant pressure drop flow is based on Depending on the flow of matter vertical movement of the body – the float is in flux and changing the area of the orifice device so that the pressure drop on both sides of the float remains constant. Some flowmeters flow, flow metering equipment called a compensation-type movement of the body flow is measured by the value of the pressure that creates the force applied to the body and balancing the dynamic flow pressure on him. Float and piston flow meters – rotameters Float constant differential pressure flowmeter consists of a float and a conical seat located in the housing instrument. Conical seat performs the same role as the tapered tube flowmeter.

The difference is that the length and diameter are approximately equal to the saddle, while the length of the tapered tube rotameters much greater than its diameter. In piston flow meter sensor is a piston that moves under the pressure of water inside the sleeve. Sleeve has an inlet and outlet, which is a diaphragm of variable section. The piston rod is connected with the core of the transmitting transducer. Flowing through the meter fluid enters the piston and raises it. This opens to a greater or lesser extent, the opening weekend diaphragm. The fluid flowing through the diaphragm, while also fills the space above the piston, which creates a reaction force.

On top of the each plate is applied a layer of acrylic primer, which in turn is covered by granules of natural stone. Additional protection of the composite tile gives a layer of transparent acrylic. Features: – Technology production of lightweight material allows you to receive – only 6.5 kg / sq. m. – Able to withstand wind gusts of up to 200 km / h.

– The cost of installation of tile is small, since the scheme laying tile is incredibly simple, but do not take work a lot of time. – Has a Class A fire resistance Storage and packaging: it is best stored on pallets (one pallet is placed 30 to 50 packs). When storing sure your tile is not exposed to direct sunlight, since otherwise the elements of the roof can stick together to protect them from the film. Do not install pallet at each other. Popular brands: ROSER (Rosero) – released in South Korea and exported to all countries in Europe, Asia and Africa. It is popular in our country. The manufacturer produces the shingles in different colors and provides a guarantee for the products within 30 years.

METROTILE (Metrotayl) – ideal for pitched roofs. Wide selection profiles, color options and accessories allows you to implement any ideas of architects and build roofs of varying difficulty. LUXARD (Lyuksard) – used in production of natural mineral granules that are exclude metallic luster. Externally very similar to tile ceramic roof, with the sale of "Lyuksard" performed at lower prices, compared to the cost of natural tile. If you need the most durable roofing material, then choose the metal shingles. It is not very suitable for mounting on the roofs of relief, but laying on the flat surface of metal tiles does not cause any trouble. At the same time metal suitable for the reconstruction of old houses, and furnishing of new ones. Sheets of metal can be made on an individual order – you can choose your size, composition (Zinc, copper and alyumotsinkovannaya), color and texture. Advantages: – high strength metal, – a wide range of colors – environmental safety – durability (manufacturers offer a guarantee for up to 50 years) – light weight (5 kg / sq. m). Installation: performing packing, remember to comply with all rules, which is rich in any installation instructions. Additionally, you must follow the recommendations of manufacturers of materials. Popular Manufacturers: METEHE (Metekhi) – the Finnish metal, resistant to heat, cold, acid rain, sea salt (which is important for coastal areas), weathering. POIMUKATE (Poymukate) – Another Finnish roofing company which uses high quality materials such well-known European manufacturers, as SSAB, Rautaruukki and Corus Plc. Polymeric sand tile is made of sand (70%), the molten polymer (25%) and high-quality dyes (5%). Once this mixture cools, it is almost impossible to destroy. Color plastic tile remains unchanged even after several decades, as the staining occurs at a stage termopressovaniya. Advantages: – appearance – it serves as a model for ceramic tiles – versatility – does not overload the rafters – the cost of laying low, because installation is quick and easy – Shock – Low thermal conductivity. Just a few steps away you from the moment when your house will be decorated and a beautiful high-quality metal, bitumen, composite or ceramic tile …

Yes, and picked up the same huge amount of negative energy from the environment. And the world has of the material world to open a black hole, no matter the channel or even energy, but only about the ongoing catastrophe of matter and energy. Gravitational collapse serves as the mechanism that causes the positive energy of matter in interaction with the negative energy of space vacuum, which accompanied by their joint annihilation. A black hole opens when a positive energy enters into deadly contact with negative energy. And closes when the celestial body as a result of the collapse completely disappeared. Therefore, the life of every black hole is estimated minutes or even seconds. Black hole – the point at which ends the annihilation of positive energy of the collapsing star and the negative energy surrounding area. To the universe for billions of years has not ceased to exist due to complete disappearance of black holes, huge amounts of energy, you need to replenish, because the law of conservation of energy in Space is enforced rigorously. Where supplied the necessary energy to our universe? Perhaps NA Kozyrev is right: a white hole-black hole antipodes! His suggestion that white space through a hole in our Universe comes the energy can be explained by the continued expansion of the universe and the birth of new galaxies. Today, the Nobel laureate Stephen Hawking in his book "Black Holes and the young universe," writes about white holes as follows: "The physical laws are symmetric in time.

Good summer in the field! Smells like flowers. The air is clean and can be seen all around far, far away. And if you run up the hill, we see further. Vaughn field ends. Behind him stretches a forest.

Near the lake glitters, the road winds. And then again on the field more. Behind him, probably also have a timber and also roads, lakes, rivers, cities It seems that the Earth – a huge, flat cake, right? Top of cake covered the sky like a huge ceiling. During the day, the ceiling blue, and night – black. And the stars light up on it as far lanterns. The ceiling seems to round, like a huge dome, and he stands on the flat edges of the tortilla – the Earth.

If a very long walk on the earth in one direction, then perhaps we can reach a place where "the sky converges with the Earth. " But this is impossible. But in ancient times, people believed that it is possible. Very seriously considered. They believed that the sky – a large inverted bowl, and the Earth – a huge cake, which has the edge. And of course, They were curious as to what was next, "beyond the edge of the earth." But no matter how much walking or traveled people who've never been able to see them "the edge of the Earth, even from afar. Obviously, people have decided, cake, on which we live, so very big, probably, its edge are somewhere far away, beyond the high mountains of forests, the seas and get to them without Humpbacked Horse is very difficult.

Advertising in magazines and newspapers is widespread and in terms of cost is second only to advertising on television. Advertising in newspapers less television. However, the playback quality of advertising in the original newspapers are usually low. Hence they placed in advertisements, are generally less attractive, and each edition has both a lot of these ads, and therefore the effect of any of them individually decreases.

Specificity of advertising in the press dictates the following specific approaches to its creation and placement: – headline should attract the consumer to give him new information, contain the main arguments and name of the product – do not be afraid of many words, because if they are all on the case, then the longest title runs even better than a short – the consumer is often inclined to take in information literally, so it’s better to do without negative returns, because in his memory may remain negative aspects associated with the subject of advertising – need to use simple, but a positive effect on all of the words such as ‘free’ ‘New’, etc. – in graphics is very valuable intrigue that draws attention – pictures are better than the picture, especially when they compare the state before and after the appearance, use of the product – a simple layout with one large illustration of the format of the magazine strip ideal advertisement in the press – make good use of them necessarily caption caption read – do not be afraid of long texts, because if the consumer interested in more detailed information, it is attracted by the headline will read the whole text – the text should be easy to grasp, without boasting, to present facts, not allegations – the credibility of the advertising increases if the photos and text reflect a picture of real life, eyewitness accounts, authoritative experts – it is not necessary to print the text light letters on a dark background it is difficult to read..
