Flowmeter with ultrasonic transducer
There are some specialized chip, Max35104, Ams GP22/GP30 and Texas TDC7200
There are a lot of site on the internet on this topic where you can found all of your answers easily and they also offer cost calculators for the reference i'm sharing a link with for more you have to google it. https://www.walmartonelogin.org/
Ultrasonic flowmeters use sound waves to determine the velocity of a fluid flowing in a pipe. At no flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe and its reflections from the fluid are the same. When the fluid moves faster, the frequency shift increases linearly. http://www.krogerfeedback.com
Is it possible to measure air flows in the range of 500 ml/min?
HOw much is it cost?
Do you make international shipping to Argentina?
Thank you very much
