Why must a thermal gas mass flow meter used to measure compressed air flow be installed after a dryer?
Since the air contains water vapor, compression by the compressor turns this vapor into water droplets. If the flow rate is measured without using a dryer, these water droplets will affect the accuracy of the flow meter’s measurements. A thermal mass flow meter operates on the principle of heat transfer to measure gas flow, and since water has a high specific heat capacity, it absorbs a large amount of heat from the heating element in such meters, thereby severely affecting their measurement accuracy. Using compressed air that has been dried before measuring flow rate will **reduce the impact of water on the measurement results**.

The correct answer is on the first floor. The only drawback of thermal mass flow meters is that they cannot measure liquids; therefore, moisture in the air can cause droplets to form on the probe, leading to significant measurement errors and inaccurate data.

Why can’t thermal mass flow meters be used to measure liquids?
I’m not very familiar with MFC; could you explain it?
