A device in the throttle body, the mass airflow, or MAF, sensor helps the engine computer determine the proper air-fuel mixture by measuring the mass of the air flowing past it. Because a precise ...

He decided to replace this with a modern mass air flow (MAF) sensor instead, and documented the process online. The output of the sensors was compared with a rig built using a vacuum cleaner to ...

Not only can the sensor fail, but vacuum hoses can develop leaks or electrical contacts can fail, triggering the warning light or causing other issues. Some vehicles use a mass air flow sensor ...

This is true for all thermal mass flowmeters, regardless of their measuring technique. Additional variations come from the sensors themselves and how each sensor is affected across its full flow range ...

Scientists based at the University of Oxford have developed a molecular flow sensor for lung function measurement. The collaboration, between chemists, physiologists, computer modellers and clinicians ...

MicroTrak has a special valve orifice design and an improved sensor technology that allows accurate measurement and control of mass flow rates earlier considered by scientists to be extremely low for ...
