Knowing if a HVAC system or fan is working efficiently for your customer is important and can be determined by the airflow it produces. Here are several techniques to measure airflow in an HVAC system ...

Who are we kidding? A variable that is not directly measured cannot be directly controlled. This is the simple fact of HVAC system airflow measuring/monitoring ...

The D6F MEMS (microelectromechanical) flow sensors use thermopiles to convert thermal energy into electrical energy. The use of a thermopile allows them to measure airflow and gas-flow speed from 1 mm ...

Online coal and primary air flow measuring devices can be helpful to more precisely balance pipe-to-pipe coal and air flows. Some utility customers have adopted on-line primary air flow measurement on ...

A first-of-its-kind study using snow during a Minnesota blizzard is giving researchers new insight into the airflow around large wind turbines. This research is essential to improving wind energy ...

Ontex Group has patented a method using a thermal imaging camera to measure airflow through channels in absorbent article cores. By loading the core with warm liquid and spraying cold fluid on the ...
