Measuring air flow in an HVAC duct can be a tricky business. Paddle wheel and turbine flow meters introduce not only resistance but maintenance issue due to accumulated dust and debris. Being able to ...

Fujita Ichiro, a Professor at the Graduate School of Engineering in Kobe University, has developed a piece of software that can measure the flow rate of rivers using image analysis. The software is ...

Rather than building ever-larger Coriolis, vortex or ultrasonic sensors, engineers can use smaller measuring paths and combine their outputs to accurately measure flow in large-diameter pipelines.

Like piezoresistive, piezoelectric, and capacitive sensing techniques devices, sensors based on thermal microelectromechanical systems (MEMS) have enabled motion sensing in accelerometers. These ...

One milligram per hour: fluid flow can be measured with great precision using a tiny ‘wobbling’ tube with a diameter of only 40 micrometers. Thanks to a new technique, the sensor, which makes use of ...

TESTA Analytical Solutions e.K reports how its real time flowmeter can be used to determine average flow rate as well as peak values of pulsation, thereby enabling selection of the most appropriate ...

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 ...

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

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 ...

New software has been developed that can measure the flow rate of rivers using image analysis, called KU-STIV (Kobe University Space-Time Image Velocimetry). This technology makes it easier to obtain ...
