Detail

Working Principle

The MEMS calorimetric sensor is installed at the flow channel wall forming a plate that serves as anadditional flow conditioner from the boundary laver configuration resulting in a laminar flow, The massflow measurement is established as the fluid carries heat away from the heater causing the redistribution ofthe temperature field. Accurate flow rate is obtained by calibration with the standard fluid at the presetconditions.

Tips: How to choose the right gas mass flow meter?

When choosing a gas mass flow meter, the following factors need to be considered:

• First is the measuring range, to ensure that the flow meter can cover the range of the actual gas flow.
• Second is the type of gas. Differences in the density of different gases may affect the measurement accuracy, so you need to confirm the type of gas that the flow meter is adapted to when choosing.
• Finally, the installation location of the device and the environmental conditions are also very important, especially the temperature, pressure and the humidity of the gas, which may affect the performance of the gas flow meter. After understanding these needs, you can choose the right brand and model.
