Types of selective gas flow meters

Gas flow meters are commonly used measurement tools in industrial production and laboratories, which can accurately measure the flow rate of gases. With the development of technology, there are now various types of gas flow meters to choose from. Below are several common types of gas flow meters.

Turbine flowmeter is a commonly used gas flowmeter that calculates the gas flow rate by measuring the speed of turbine rotation. This type of flowmeter has advantages such as high accuracy, good stability, and wide range, and is suitable for various gas media, such as air, oxygen, nitrogen, etc.

Thermal gas flow meter uses the principle of thermistor to calculate the gas flow rate by measuring the temperature change after the gas absorbs heat. This type of flowmeter has the advantages of fast response speed, high measurement accuracy, and good reliability, and is suitable for measuring gases with high temperature, high pressure, and high humidity.

Differential pressure gas flowmeter uses the principle of throttling to calculate the gas flow rate by measuring the pressure difference of gas at the throttling element. This type of flowmeter has the advantages of simple structure, low price, and high reliability, and is suitable for measuring gases with low flow rates and pressures.

Ultrasonic gas flowmeter uses the principle of ultrasound to calculate the gas flow rate by measuring the propagation speed of sound waves in the gas. This type of flowmeter has the advantages of non-contact measurement, high measurement accuracy, and wide applicability, and is suitable for measuring various gas media, such as natural gas, coal gas, etc.

A mass flow meter is an instrument that directly measures the mass flow rate of gas. It calculates the gas flow rate by measuring the mass of gas flowing through a certain volume over a certain period of time. This flowmeter has the advantages of high measurement accuracy and good stability, and is suitable for measuring various gas media, such as hydrogen, oxygen, etc.

The above introduces several common types of gas flow meters, each with its unique advantages and applicability. In practical applications, appropriate gas flow meter types should be selected based on specific needs to ensure measurement accuracy and reliability.
