A peak flow meter is an inexpensive, portable, handheld device for those with asthma that is used to measure how well air moves out of your lungs. Measuring your peak flow using this meter is an ...

At a glance, the primary function of a flow meter is quite straightforward – to measure the volume or mass of a liquid passing through it. But the many variables in industrial settings magnify the ...

The accuracy of the mass flow controller (MFC) is important to ensure the performance, quality, and efficiency of a flow meter. If an instrument is not calibrated, its performance can decline as a ...

The Flow Meter reference design, built around the MC9S08GW64 microcontroller, is useful for engineers seeking reliable, low-power, and cost-efficient solutions in gas and fluid metering applications.
