2. What is the principle and function of gas flo
The core function of gas flow meter is to accurately measure the flow of gas in pipelines or equipment. Its working principle varies according to different technical types of wheel cracking, and it serves key fields such as industry, energy, environmental protection, and medical care together.
. 1. Working principle: Gas flow meters are designed based on different physical principles and are mainly divided into the following types: differential pressure flow meters are based on the Bernoulli principle. They measure the pressure difference before and after gas flow by installing throttling devices (such as orifice plates) inside the pipeline to calculate the flow rate. Thermal flow meters utilize the heat conduction effect. After the sensor is heated, the gas flow will take away its heat. The flow rate value is obtained by monitoring the corresponding relationship between temperature changes and flow rate. The vortex flowmeter places a blocking fluid in the flow channel, and alternating vortices are generated when gas flows through. The frequency is proportional to the flow velocity, and the detection frequency can be used to convert the flow rate. Positive displacement flowmeter divides gas into fixed volume units through mechanical structure, counts the number of units passed in a unit time, and accumulates the total flow rate. Its main function is to control the production process in industries such as chemical and power. Accurate gas flow measurement is the basis for ensuring reaction conditions, optimizing production efficiency, and stabilizing product quality. Energy measurement and trade settlement are widely used for measuring the consumption of energy gases such as natural gas, ensuring fair tra
