Vortex flowmeter measurement techniques and application instructions

The flow measurement is independent of the fluid's activity. The elliptical gear vortex flowmeter is metered by the pressure of the measured medium to propel the elliptical gear. The smaller the viscosity of the medium, the smaller the amount of leakage from the gear and the metering gap, the larger the viscosity of the nuclear medium, and the smaller the leakage error, the better the measurement.
The elliptical gear vortex flowmeter has high measurement accuracy and is used for the measurement of high viscosity medium flow, but it is not used for fluids containing solid particles. If the liquid medium is mixed with a gas, it will cause measurement errors.
The use of flow measurement techniques and instruments is largely in the following categories.
First, the history of industrial consumption
Flow meter is one of the major instruments in the process of active instrumentation and installation. It is widely used in metallurgy, electric power, coal, chemical, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection and nationals. Everyday life and other areas of the national economy are important tools for industrial and industrial consumption, diligence, improvement of product quality, improvement of economic efficiency and governance. In the process of active instrumentation and installation, the flow meter has two major functions: as the process of mastering the system's instrumentation and measuring the total amount of materials.
Second, the dynamic measurement
Power is divided into primary power (coal, crude oil, coalbed methane, petroleum gas and natural gas), secondary power (electric power, coke, artificial gas, refined oil, liquefied petroleum gas, steam) and energy-carrying medium (shrinking air, oxygen) , nitrogen, hydrogen, water, etc. Power metering is an important driving force for scientific management, energy conservation and consumption reduction, and economic benefits. Flow meters are an important part of power metering. The rare power of water, artificial gas, natural gas, steam and oil uses an extremely large number of vortex flowmeters, which are indispensable for power management and economic accounting. tool.
Third, the environmental cover project
The emission of flue gas, waste liquid, sewage, etc., greatly purifies the atmosphere and water resources, which is a major threat to the human life environment. The country has made continuous development a national policy, and environmental protection will be the biggest issue in the 21st century. The purification of air and water must be mastered, and it is necessary to strengthen the governance, and the basic management is the quantitative mastery of the purification amount.
In China, where coal is an important driving force, millions of chimneys throughout the country continue to emit smoke into the atmosphere. The mastery of flue gas emissions is an important name for radical purification. Each chimney must be equipped with a flue gas analysis instrument and a vortex flowmeter to form a continuous emission monitoring system. The flow rate of flue gas is very difficult. The difficulty is that the chimney is large in size and irregular in shape, the gas composition is changed, the flow rate is large, dirt, dust, erosion, low temperature, and no straight pipe section.
