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, ...

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 ...

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 ...

image: A noninvasive method for measuring brain blood flow with light has been developed by biomedical engineers and neurologists at UC Davis, and used to detect brain activation. The new method, ...

Pulsating flow systems can be seen in process applications where the velocity profile of the flow undergoes dramatic cycling changes as compared to normal steady flow conditions. Such conditions are ...

This article describes how a multivariable pressure transmitter with built-in dynamic compensation can correct for many of the errors and inaccuracies that can occur in differential pressure based ...

Here is an introduction to the low cost anemometer (wind sensor) from Modern Device (http://moderndevice.com) . This small sensor suitable for electronic experiments ...

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 ...

Know your options when selecting the appropriate flowmeter technology to measure natural gas, water, and steam in power generation. In many chemical plants, the electricity the plant uses is derived ...
