A peak flow meter is a handheld device that measures airflow rate and can help those with respiratory conditions like asthma ...

A peak flow meter is used to measure your peak expiratory flow rate (PEFR). PEFR describes how quickly your lungs expel air during a forceful exhalation after you fully inhale. Regularly conducting a ...

Rotameter flow meters are devices that can measure the flowrate of liquids and gases. Generally, the rotameter is a tube made of plastic, glass or metal combined with a float, which responds linearly ...

The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

These are the type of flow meters that measure the velocity of liquid or gas by using the principle of ultrasound or sounds waves. Fast digital signal processors and sophisticated signal analysis ...

A peak expiratory flow rate (PEFR) measures how effectively you exhale. Also called a peak flow meter, this handheld device helps you document the amount of air and the speed at which you can ...

In industrial markets, semiconductor chipsets play a huge role in the transformation of mechanical equipment to electromechanical or purely-electronic equipment. Every market segment is broken down ...

Flow measurement is the quantification of bulk fluid or gas movement. Volumetric flow rate is sometimes measured in "standard cubic centimeters per minute" (abbreviation sccm), a unit acceptable for ...

Coronary flow reserve (CFR) is a key sign of coronary artery disease, namely how the coronary arteries that feed blood to the heart may adapt to various physiological situations such as exercise, ...

One of the primary objectives for the application of flow cytometry in any testing environment should be measurement assurance, i.e., the generation of reliable and reproducible results. This goal can ...

Uneven distribution of coal flow to burners can lead to higher NOx emissions and increased operating costs. A new laboratory is studying measurement instruments and control approaches to help power ...
