Application range of vortex flowmeter

Vortex flowmeter flow measurement technology and instrumentation applications in the following areas.

Industrial production process

The flow meter is one of the major categories of instrumentation process automation instrument and device, it is widely used in various fields of economic power, metallurgy, coal, petroleum, chemical industry, transportation, construction, textile, food, medicine, agriculture, environmental protection and people's daily life and national development, industrial and agricultural production, energy conservation, improvement the quality of the products, an important tool for improving the economic benefit and management level plays an important role in the national economy. In process automation instruments and devices, the flow meter has two major functions: as a process automation control system, a measuring instrument and a measurement of the total quantity of materials.

Energy measurement and energy into primary energy (coal, crude oil, coal gas, liquefied petroleum gas and natural gas), two energy (electricity, coke, artificial gas, refined oil, liquefied petroleum gas, steam and energy) refrigerants (compressed air, oxygen, nitrogen, hydrogen, water etc.). Energy metering is an important means of scientific management of energy, energy saving and economic benefits improvement. The flow meter is an important component of energy meter, water, artificial gas, natural gas, steam and oil these commonly used energy using a very large number of the flow meter, they are indispensable tools for energy management and economic accounting.

Environmental protection engineering

The emission of flue gas, waste water and sewage seriously pollute the atmosphere and water resources, and seriously threaten the living environment of human beings. The state regards sustainable development as a national policy, and environmental protection will be the biggest subject in twenty-first Century. Control of air and water pollution must be strengthened, and management is based on quantitative control of the amount of pollution.

China is a country with coal as the main energy source, and millions of chimneys all over the country continuously discharge smoke into the atmosphere. Flue gas emission control is an important project to cure the pollution, each chimney must be gas analytical instruments and meters installed, connected case emission monitoring system. The flow volume of flue gas has great hang difficulty, it is difficult to chimney size and irregular shape, gas composition changes, velocity range, dirt, dust, corrosion, high temperature, no straight pipe etc..

Transportation

There are five modes: railway, highway, aviation, water transportation and pipeline transportation. Although pipeline transportation has long existed, it is not widely used. With the prominent environmental problems, people pay more attention to the characteristics of pipeline transportation. Pipeline transportation must be equipped with a flow meter, which is the eye of control, distribution and dispatch, as well as an indispensable tool for safety supervision and economic accounting.

Main problems and solutions of vortex flowmeter

The main problems are

Vortex flowmeter analysis and solution

To sum up the main causes of these problems, mainly related to the following aspects:

Requirement of installation of vortex flow meter to straight pipe section:

The installation of vortex flowmeter is very important to the straight pipe section. Its detailed requirements are as follows:

The flow meter has certain requirements for the upper and lower straight pipe sections on the installation point, otherwise it will affect the measurement accuracy.

Typical brands of vortex flowmeter: Rosemont, Cowell, E, H, TECK/, Tektronix, meters, etc.
