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 ...

[Nubmian] wrote in to share his experiments with measuring airflow in an HVAC system. His first video deals with using with ultrasonic sensors. He found an interesting white paper that described ...

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 ...

Cleanrooms are one of the most energy intensive facilities per square foot. Most cleanroom airflows are determined by industry-accepted air change rates and airflow velocities. Typically, cleanroom ...

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 ...

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 ...
