Ultrasonic flow meters use sound waves to determine flow rates. They can be either Doppler Effect meters or Time-of-Flight meters. Doppler Effect meters measure the frequency shifts caused by fluid ...

Ultrasonic flow meters such as Doppler devices may use this type of mounting to read the flow through the pipe. Search Logic: All products with ANY of the selected attributes will be returned as ...

Being able to measure ducted airflow cheaply and non-intrusively, like with this ultrasonic flow meter, could be a big deal for DIY projects and the trades in general. The principle behind the ...

His first video deals with using with ultrasonic sensors. He found an interesting white paper that described measuring airflow with a single-path acoustic transit time flow meter. The question ...
