Aplicaciones de los caudalímetros másicos de gas térmicos

Thermal diffusion technology is a technology with excellent performance and high reliability under harsh conditions, and is applied to gas mass flow meters. Its typical sensing elements include two thermal resistors (platinum RTD), one is a velocity sensor, and the other is a temperature sensor that automatically compensates for changes in gas temperature. Understanding the common application range of gas mass flow meters facilitates further selection. Gas mass flow meters are mainly used in the following fields: 1. Power industry: hydrogen measurement; gas measurement in gas furnaces; gas measurement during gas distribution in fuel systems; measurement of primary and secondary air in blast furnaces in power plants; measurement of various gases in boilers and auxiliary systems. 2. Chemical industry: ammonia measurement in fertilizer plants; flue gas circulation monitoring; gas flow measurement in sampling systems; various gas flow measurements in battery factories; gas flow measurement of induced draft fans.

3. Metallurgical industry: measurement of coke oven gas in coking plants; measurement of gas filling in steel plants; measurement of blast furnace gas in iron and steel plants; control of hydrogen, oxygen, nitrogen and other gases in heat treatment quenching furnaces, etc.; measurement and control of heating furnace gas (blast furnace gas, coking gas, natural gas, etc.) in steel rolling mills.

4. Oil and gas industry: energy exchange; gas metering; natural gas measurement; well filling gas recovery; leak gas testing; flare gas monitoring; gas quality analysis.

5. Food and pharmaceutical industry: ventilation system; carbon dioxide treatment in breweries; gas flow measurement in thermal oxidation processes; boiler intake, exhaust, process control; addition of fresh air in processing operations; hot air flow in bottle sterilizers.

6. Pulp and paper industry: flue flow monitoring; boiler recovery of secondary/tertiary air; boiler gas and air supply measurement; gas measurement in wastewater treatment systems.

7. Public works - monitoring of electricity, gas and water treatment: biogas, coal gas, natural gas, liquefied gas, general systems, pipeline gas, boiler preheated air.
