Measuring Principle of Ultrasonic Flowmeters | KROHNE

And I learned exactly what I was hoping to 👍

[@iprant]

Very good explanation.Thanks

[@gawaspec548]

nice job sir!

[@christopher8199]

thanks

[@NAKIOTOKENZI]

How it come for the formular of average flow velocity?

[@benrejeboussama6166]

1/Tab - 1/Tab

[@pauloesperon7697]

Does the frequency range of the transducer's signal depend on the medium?

[@pawan8542]

can we take alha=90 degree?

[@ivo2111]

No, we cant. If we make alpha to be 90 degrees, transit time difference would be zero, in which case we cant measure the flow rate

I enjoyed the video. I have a question.
Looking at the path that ultrasound crosses, it seems to pierce the wall twice in the middle.
By the way, can ultrasound penetrate a blocked wall?
My experiment showed that ultrasound couldn't penetrate the wall.
So I wonder if ultrasound can pass through obstacles.

Hi! Thanks for your questions. Please feel free to register for our free eLearning courses at KROHNE Academy online: academy-online.krohne.com. Here, you will find a course on ultrasonic flowmeters in general (academy-online.krohne.com/en/courses/ultrasonic-flowmeters/), but also a course on ultrasonic clamp-on flowmeters (academy-online.krohne.com/en/courses/clamp-on/). This technique allows indeed also to send ultrasonic signals through pipe walls. Best regards!

Do the sensors need to make contact with the medium

[@NAKIOTOKENZI]

I doub Vcos@ (V is Vm?) It means Vmcos@ = Vcos@ ?

[@MrSolomez]

how'd you get the area equation??

[@armijinyawa]

Very clear. Thank you!

[@syauqisabili3776]

what is the unit of Q(flow rate) ?

[@RaviYadav-fr9xl]

M3/s or litter/sec
