Understanding Insertion Mass Flow Meter: An Efficient Gas Flow Measurement Solution

An insertion mass flow meter, also known as an insertion thermal gas flow meter, is a vital tool in the field of gas flow measurement. This instrument offers a unique and efficient method to accurately measure gas flow rates. In this article, we will delve into the working principle, measurement of gas types, technical specifications, and advantages of using insertion mass flow meters.

Working Principle and Gas Type Measurement by insertion mass flow meter

The insertion mass flow meter operates on the principle of thermal dispersion. It measures the mass flow rate of gases by utilizing the cooling effect of a gas stream on a heated probe. As the gas flows past the heated probe, it absorbs heat, and the sensor compensates by increasing the power to maintain a constant temperature. The power required to maintain the temperature is directly proportional to the mass flow rate, allowing for accurate measurement.

This insertion mass flow meter can measure various gas types, including but not limited to air, nitrogen, oxygen, natural gas, biogas, LPG, and other industrial gases. The principles remain the same regardless of the gas type, making it a versatile solution for a wide range of gas mass flow measurement applications.
