APPLICATION

Industries

Aerospace

The technology of A+K balanced differential pressure flowmeter originates from NASA, It was mainly designed and developed for the measurement of liquid oxygen and liquid hydrogen, of the main engine of the space shuttle. Later, it was introduced into China and applied to Chinese space industry. At present, it is being used in China's five major space launch centers.

More

Nuclear Industry

The nuclear industry uses nuclear energy to convert into electricity, heat and mechanical power. At the same time, in the development of national economy, nuclear industry also plays an extremely important position and role. A+K products are used in high temperature and high pressure small diameter loops, nuclear island second loop, high temperature and high pressure water flow test equipment, etc., we meet the strict requirements of the industry and running stabilities.

More

Petrochemical Industry

The petrochemical industry is a chemical industry with oil and natural gas as raw materials. The petrochemical industry has become the basic industry in the chemical industry and occupies a very important position in the national economy. For olefins such as ethylene, propylene, butadiene and aromatic hydrocarbons such as benzene, toluene and xylene, A+K balanced products can give full play to the advantages of products to solve the difficulties in industry measurement, and can reduce energy consumption, cost and efficiency of equipment.

More

Metallurgy

The metallurgical industry, involves the measurement of the flow of various gases, vapors and liquids. Balance flowmeter is a commonly used differential pressure measuring instrument, which has a good performance on measuring converter gas and blast furnace gas in iron making, steel making, steel rolling and other processes.

More

Glass Building Material

Chinese glass production mainly adopts float glass process. There are nearly 200 float lines, which is greater than half of the world's production capacity. The float glass process can be simply divided into glass melting, waste heat recovery, smoke exhaust gas supply and other parts. The precision of raw material ratio is high, and the finished product rate is strictly controlled. A+K balance flowmeter has a leading edge in the glass industry.

More

Electric Power Industry

The electric power industry involves thermal power generation, gas turbine power generation, garbage environmental power generation, distributed energy, biomass power generation and solid waste power generation, waste heat power generation, new energy/photovoltaic power generation, heating transformation/heat network metering, etc. The main advantages of balanced flowmeter lie with in the special conditions such as high temperature and high pressure, and the overall processing form of AKET meets the requirements of 515 "Regulation on Safety Technology for Boiler".

More

Cryogenic Air Separation

The acquisition of low temperature is closely related to the liquefaction of gas. The cryogenic liquid separation method has become the first choice to adapt to large-scale industrial production. Cryogenic liquid is easy to gasify after pressure loss, A+K balance flowmeter adopts porous balance structure, with a small permanent pressure loss, it can significantly reduce gasification. At the same time, A+K balance flowmeter's is overall filled with the measuring liquid, thus it's body stays at a constant cryogenic temperature, further reduce gasification problem, and improve the measurement accuracy.

Bio-Pharmaceutical

In the process of pharmaceutical production, hydrogenation reaction is very common, including aromatic ring hydrogenation, hydrogen nitrogen release, hydrogen oxygen release, olefin hydrogenation and other major reaction types. However, in the process of hydrogenation, unreasonable ratio, too large of pressure or temperature will lead to danger. Balance flowmeter can well solve such problems.

More

Municipal Administration

In municipal gas, heat pipe network, water treatment and other fields, A+K balance products has unique sensor structure, because of its high precision, low pressure loss, easy installation, short straight pipe section requirements, easy maintenance and other characteristics, it is widely used in the industry. It also can achieve two-way measurement, can be used as a trade measurement device.
