Sewage flow meter is a commonly used flow meter, is based on Faraday's law of electromagnetic induction flow measurement flow meter. The advantages of the flowmeter is a very small pressure drop, measurable flow range. The maximum flow rate and the minimum flow ratio is generally 20: 1 or more, the applicable industrial pipe diameter range, up to 3m, the output signal and the measured flow into a linear, high accuracy, measurable conductivity ≥ 5μs / cm Acid, alkali, salt solution, water, sewage, corrosive liquids and mud, pulp, pulp and other fluid flow.
Application of sewage flow meter
The flow meter is one of the major instruments in the process automation instrumentation and installation. It is widely used in metallurgy, electric power, coal, chemical industry, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection and people's daily life And other areas of the national economy is the development of industrial and agricultural production, energy conservation, improve product quality, improve economic efficiency and management of an important tool in the national economy occupies an important position. In the process of automation of instruments and devices, the sewage flow meter has two functions: as a process automation control system for measuring instruments and measuring the total number of materials.
Energy is divided into primary energy (coal, crude oil, coalbed methane, LPG and natural gas), secondary energy (electricity, coke, artificial gas, refined oil, liquefied petroleum gas, steam) and load energy (compressed air, Nitrogen, hydrogen, water) and so on. Energy measurement is an important means of scientific management of energy, to achieve energy saving, improve economic efficiency. Flowmeters are an important part of energy metering instruments. Water, artificial gas, natural gas, steam and oil. These commonly used energy sources use extremely large flowmeters, which are an indispensable tool for energy management and economic accounting.
Flue gas, waste water, sewage and other serious pollution of the atmosphere and water resources, a serious threat to human survival
surroundings. The state will be sustainable development as a national policy, environmental protection will be the biggest issue in the 21st century. Air and water pollution to be controlled, must strengthen the management, and management is based on the quantitative control of pollution, through the sewage flow meter can be very convenient management of sewage.
China is the country as the main energy of coal, the country has millions of chimneys kept to the atmosphere emissions of flue gas. Flue gas emissions control is an important project to cure pollution, each chimney must be installed flue gas analysis instrument and flow meter, composed of emission monitoring system. Flue gas flow has a lot of difficulties, it is difficult for the chimney size and irregular shape, gas composition changes, flow range, dirt, dust, corrosion, high temperature, no straight pipe and so on.
There are five ways: railway road, air, water transport, and pipeline transportation. Pipeline transport which has long been, but the application is not common. With the prominent environmental issues, the characteristics of pipeline transportation has attracted people's attention. Pipeline transport must be equipped with a flowmeter, which is the control, distribution and scheduling of the eye, is also an essential tool for security supervision and economic accounting.
The 21st century will usher in the life sciences of the century, biotechnology is characterized by the industry will be rapid development. Biotechnology to monitor the measurement of many substances, such as blood, urine and so on. Instrument development is extremely difficult, wide variety.
Scientific experiments need not only the number of flow meters, and the variety is extremely complex. According to the statistical flowmeter a large part of more than 100 kinds of scientific research will be used, they are not mass production, in the market for sale, many scientific research institutions and large enterprises are set up special team developed a dedicated flow meter.
These areas are open flow path, generally need to detect the flow rate, and then calculate the flow. The physical and hydrodynamic basis of the flowmeter and flowmeter is common but the instrument principle and structure and the conditions of use are very different.
