Thermal gas mass flow meters measure steam flow

Project Overview

The working principle of the thermal gas mass flow meter is based on the principle of thermal diffusion. By measuring the heat absorbed by the gas on the heating element, the gas mass flow rate flowing through the pipeline is determined. Although it is usually used to measure the mass flow of gas, it is not suitable for measuring the flow of steam.

Because steam has a high enthalpy value, its temperature is high and it is prone to phase changes, resulting in poor heat diffusion. In addition, the density and specific heat capacity of steam are different from those of gases. These factors make the heat The gas mass flowmeter cannot accurately measure the flow rate of steam.

Therefore, the thermal gas mass flowmeter cannot be used to measure steam flow due to its working principle. But we can choose other flow meters such as V-cone flow meters, vortex flow meters, etc.
