Application of orifice flow meter in gas mixture

Abstract: The application information of orifice flowmeter in gas mixture is provided by excellent flowmeter and flowmeter manufacturers. ZK standard orifice plate is a differential pressure generating device for measuring flow. It can measure the flow of various fluids in the pipeline with various differential pressure gauges or differential pressure transmitters. Orifice flowmeter throttling device includes annular chamber orifice, nozzle, etc. Orifice flowmeter with orifice or differential pressure transmitter. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the application article details of orifice flowmeters in gas mixture. ZK standard orifice plate is a differential pressure generating device for measuring flow. It can measure the flow of various fluids in the pipeline with various differential pressure gauges or differential pressure transmitters. Orifice flowmeter throttling device includes annular chamber orifice, nozzle, etc. The orifice flowmeter throttling device is used in conjunction with a differential pressure transmitter or a U-shaped pressure gauge to measure the flow of liquid, steam and gas. Therefore, the orifice flowmeter is widely used in petroleum, chemical, metallurgy, electric power, light industry, etc. department. When the fluid that fills the pipeline, when it flows through the throttling device in the pipeline, the flow beam will form a local contraction at the throttling part of the throttling device, so that the flow rate increases and the static pressure is low, so the flow is generated before and after the throttling part. The pressure drop, that is, the pressure difference, the greater the flow rate of the medium flow, the greater the pressure difference generated before and after the throttle, so the orifice flowmeter can measure the fluid flow by measuring the pressure difference. This measurement method is based on the law of conservation of energy and the law of flow continuity. Intelligent throttling device (orifice flowmeter) is a new generation of flowmeter that integrates flow, temperature and pressure detection functions and can automatically compensate for temperature and pressure. The orifice flowmeter adopts advanced microcomputer technology and micro power consumption. New technology, strong function, compact structure, simple operation and convenient use. 2.

It is often produced in mines.“gas”The explosion directly threatens the safety of miners. Therefore, mine work is“gas”We attach great importance to it. In addition to taking some necessary safety measures, some miners will carry a birdcage with canaries down to the mine and hang the birdcage in the working area. It turns out that the canary pair“gas”or other poisonous gases are particularly sensitive, as long as there is a very thin“gas”Produced, far from having a lethal effect on the human body, the canary has already lost consciousness and passed out. After the miners perceive the situation, they can immediately withdraw from the mine to avoid casualties. When measuring the flow of the gas mixture, it cannot be measured with a flow meter with a power supply, so it is necessary to understand the characteristics of the gas mixture when selecting a flowmeter for measurement. What is gas? Gas, speaking of its other name, biogas, most people may understand a lot. Actually it is from the irregular pronunciation of English and Russian. The original meaning of Gas is gas, including all kinds of flammable and non-flammable gases. The main component of gas is methane, its chemical element symbol is CH4, a non-toxic, odorless, colorless gas that can be burned. It is widely used for boiling water, cooking, and lighting. In coal mines it spews out of cracks in the coal rock. Mine gas explosion is a thermal chain reaction (also called a chain reaction). When the explosive mixture absorbs a certain amount of energy (usually the heat energy given by the ignition source), the chain of the reaction molecule is broken and dissociated into two or more free radicals (also called free radicals). Such free radicals have great chemical activity and become the active center for the continuous reaction. Under suitable conditions, each free radical can be further decomposed to generate two or more free radicals. In this way, there are more and more free radicals, and the chemical reaction speed is faster and faster, and finally it can develop into a combustion or explosive oxidation reaction. Therefore, gas explosion, in essence, is a violent oxidation reaction produced by a certain concentration of methane and the moderate action of air.
