MEMS Flow Sensors Features
Realizing a highly accurate flow measurement, sensing even a single flap of a butterfly’s wings
Omron’s MEMS flow sensor accurately detects minute airflow so much as a single flap of a butterfly’s wings.
A gas flow sensor capable of “measuring mass flow” independent of temperature and pressure.
Mass Flow Measurement
|Q1||There are two balloons; each having different volumes. But these balloons have the same mass. Why is that?|
|The volume increases/decreases according to the pressure and temperature changes. The mass, on the other hand, remains constant regardless of the environmental changes. The mass flow measurement allows measurement performance that is not affected by the changes in the environment.|
|Q1||Why is mass flow measurement required?|
|An accurate measurement of the flow is required especially for combustion control. Omron’s flow sensor enables measuring the gas flow based on the mass flow measurement.|
Principles of MEMS Flow Sensor Measurement
Highly Resistant to Dust
Built-in Dust Segregation System (cyclonic)
The sensor can be placed anywhere thanks to its dust-resistant structure. Omron’s unique design of 3D flow path provides a high level of reliability by separating dust particles to reduce its effect on the sensor chip. Additionally, Omron succeeded in reducing the sensor size, allowing it to be used in wider range of applications.
