Selection and use of high-pressure gas flowmeter in the metallurgical industry

Project Overview

As one of the pillar industries of the national economy, the metallurgical industry has strict requirements for gas flow measurement. The accurate measurement of high-pressure gas flow is not only related to the efficiency and quality of metallurgical production, but also closely related to production safety. Therefore, choosing a suitable gas flow meter has become the top priority for metallurgical enterprises.

Thermal gas flow meter working principle and advantages

Thermal gas flow meter is a flow measurement device based on the principle of heat transfer. Its working principle is based on measuring the change in heat generated by the gas passing through the sensor. As gas flows through the heated wire, the fluid removes heat, causing the wire temperature to drop. By measuring the temperature change of the heating wire, the gas flow rate can be calculated.

Compared with traditional flow meters, thermal gas flow meters have the following advantages:

1. High precision: The thermal gas flow meters have high measurement accuracy and can meet the needs of metallurgical applications. The industry has precise requirements for flow measurement.

2. Fast response: Due to its simple structure, the thermal gas flow meter has a fast response speed and is suitable for scenarios with high requirements for flow changes.

3. Strong pressure resistance: The metallurgical industry often needs to measure high-pressure gas flow, and the thermal gas flow meter can work stably in a high-pressure environment.

4. No moving parts required: The thermal gas flow meter requires no moving parts, reducing the possibility of maintenance and failure.

Application cases of thermal gas flow meters in the metallurgical industry

1. High-pressure oxygen measurement in the iron-making process: In the iron-making process, high-pressure oxygen is an indispensable raw material . By installing a thermal gas flow meter, the flow rate of high-pressure oxygen can be accurately measured to ensure the stable progress of metallurgical reactions and improve production efficiency.

2. High-temperature gas measurement: Accurate measurement of the flow rate of high-temperature gas generated in metallurgical furnaces is crucial for controlling the atmosphere in the furnace and ensuring product quality. Thermal gas flow meters can still work reliably in high-temperature and high-pressure environments and are suitable for such scenarios.

3. Hydrogen measurement in steelmaking: In some newsteelmaking processes, hydrogen is widely used in the smelting process. Thermal gas flow meters perform well when measuring hydrogen flow, and their high accuracy and pressure resistance ensure the stability of smelting reactions.

Through reasonable selection and use, metallurgical enterprises can give full play to their advantages and improve production efficiency and product quality.
